Make native Apple M1 CPU distribution

[Tom Goddard]

Apple is replacing Intel CPUs in all machines with ARM cpus. Already have Mac laptop and Mac Mini models with ARM (Apple M1) cpu since late 2020. Apple M1 CPU is 5 nm process vs 10 nm for latest Intel cpus so much more energy efficient, or higher performance at comparable energy.

Macs use Rosetta 2 to run Intel apps on ARM cpu machines. This seems to be working fine for ChimeraX. Native ARM ChimeraX may give higher performance. Python is reported to run up to 3 times faster on ARM cpu vs Intel emulation on Mac.

We proposed making native ARM version in Chan-Zuckerberg Science Initiative (CZI) Essential Open Source Software proposal submitted May 15, 2021 with possible funding date Sept 1, 2021.

[Tom Goddard]

We got a Mac Mini, May 2021.

I built relocatable native ARM Python 3.8.10 from standard Python distribution. The standard Python on Mac is not relocatable so this uses Greg Neagle's relocatable-python github project (Makefile.macos in prereqs/Python) which did not work without modifying Python fetch since ARM Python uses file name with macos11 while Intel version uses macosx10.9 (with an x in the name). I just hand edited relocatable-python and ran it by hand.

ChimeraX build then fails on PyQt because there are no ARM wheels available at PyPi. Will ask if these can be added on the PyQt mailing list.

[Tom Goddard]

It is not clear whether Qt is working on macOS arm64 cpus. Here is the Qt ticket for this "Qt for macOS on Apple Silicon (arm64)":

​https://bugreports.qt.io/browse/QTBUG-85279

This ticket is "priority 2" and the "affects" field says 5.15, 6.x but "fix version" field says 6.2. So it may be that 5.15 will not be distributed for Mac arm64.

[Tom Goddard]

Homebrew offers Qt5 for arm64

​https://formulae.brew.sh/formula/qt@5

Homebrew also claims to offer PyQt5 for arm64

​https://formulae.brew.sh/formula/pyqt@5

Should test this. Maybe these are really Intel binaries that run using Rosetta 2.

[pett]

Oooh, that's ugly. It's looks like you are most likely to get two separate single-architecture builds in the short term (and maybe forever), which you would have to "lipo" together yourself. No idea how PyQt would handle that. We might have to offer two separate ChimeraX Mac downloads. Ugh.

[Tom Goddard]

The homebrew pyqt5 and qt5 are native arm64 builds. Can probably use those for a test.

[Tom Goddard]

I made a relocatable arm64 Python 3.9.6 from the standard python distribution.

I tried homebrew arm64 PyQt5 in the homebrew python 3.9.6, imports. May be able to copy this to the ChimeraX Python. May not be relocatable. Need to try it.

Commented out prereqs builds of ambertools, openmm, PyQt, pytables. OpenMM has a native arm64 build but not going to mess with that now.

Prereqs pip app-install various packages have no arm64 wheel and cannot be built from source: imagecodecs, matplotlib, netcdf4, scipy.

mk/os.make had hardcoded x86_64 in BIN_PLATFORM used in wheel names. Changed this to arm64. Also used OSXVER = 11.3 in core wheel file name and pip install said that is not a supported platform and required 11.0. Not sure why.

h5py used by emdb_sff bundle (segmentation file reader) failed to install. Error dlopen(libhdf5.dylib): image not found. Removed emdb_sff.

Core and all bundles and main app all built. Compiler flags list both arm64 and x86_64, so maybe it is compiling both g++ -arch arm64 -arch x86_64 ....

[Tom Goddard]

Copying homebrew site-packages/PyQt5 (and with rsync -av --copy-links) and trying to start ChimeraX shows homebrew PyQt5 does not include QtWebEngineWidgets. This is confirmed online, and homebrew does not offer QtWebEngine. So I have no arm64 build of QtWebEngine in PyQt5. ChimeraX will start in nogui mode with lots of error messages because even in nogui mode it tries to import QtWebEngineWidgets.

After commenting out various places where ChimeraX imports QtWebEngineWidgets at startup I got ChimeraX gui to come up without errors. Here are the things that needed to be commented out or disabled. The main losses are the Log panel and recent file history thumbnails.

1) scheme_mgr/manager.py -- return from SchemesManager.add_provider() which is called by toolshed/init.py
2) UI class init() in ui/gui.py imports QtWebEngineWidgets before creating QApplication. Comment that out.
3) MainWindow in ui/gui.py creates FileHistory for showing thumbnails in graphics area. Comment that out.
4) ui/widgets/init.py imports HtmlView. Comment that out.
5) Log panel uses html. Make that not autostart.

With these edits ChimeraX starts and loading PDB models, showing atoms, calculating surfaces worked.

On a 2021 Mac Mini (Macmini9,1) with Apple M1 processor, macOS 11.3 and 16 Gbytes memory here are some timings of native ARM vs Intel and also of 2019 MacBook Pro (MacBookPro15,3), 32 Gbytes memory, Intel i9 8-core 2.4 GHz processor. The Mac Mini CPU uses about half the power of the Mac Book Pro. Used the ChimeraX time command for all results.

[Tom Goddard]

Should time the same actions with Intel ChimeraX (same version with Python 3.9) running under Rosetta emulation to see how much a native build will speed things up. Will wait for tomorrow's Python 3.9 ChimeraX build to test this.

Added these times to previous comment.

[Tom Goddard]

Qt has announced that Qt 6.2 will support Apple Silicon (arm64) and prerelease 6.2 versions are available now

​https://www.qt.io/blog/qt-on-apple-silicon

They also say they will look at arm64 for Qt 5.15.4 commercial LTS. Others say they have built Qt 5.15 for Apple Silicon, but official support is unclear.

[Tom Goddard]

Qt 6.2 is expected out in September 2021. We might want to port ChimeraX to Qt 6.2 before trying do distribute native arm64 ChimeraX.

[Tom Goddard]

Here are all the problem dependencies for making a native arm64 ChimeraX

Qt 5, PyQt5, ambertools, pytables, h5py, imagecodecs, matplotlib, netcdf4, scipy

Posts online talk about successfully using homebrew or miniconda to get matplotlib and scipy.

​https://solarianprogrammer.com/2021/06/15/install-python-numpy-scipy-matplotlib-macos-apple-silicon-arm64/
​https://github.com/h5py/h5py/issues/1810

Posts online also describe compiling PyTables and h5py from source and that hdf5 is available for arm64.

​https://github.com/PyTables/PyTables/issues/832

Ambertools compile.

​http://archive.ambermd.org/202103/0133.html

Netcdf4 did not see anyone succeeding.

[Tristan Croll]

Supporting Apple Silicon will take a bit of work for me, I think. The big stumbling block will be the Intel MKL library I'm using to replace FFTW2 in Clipper - as far as I understand, the MKL is firmly tied to x86_64 architecture. So I'd have to find and integrate a replacement, which will take a fair bit of work. Not impossible, but far from trivial.

[goddard@…]

The macOS arm64 port is going to be a fair bit of work getting several packages ported (ambertools, pytables, matplotlib, ...) and I think we are aiming to do this within about 6 months.  We have asked for some funding to support this in a Chan-Zuckerberg Science essential software proposal and we should hear if it gets funded by the end of July.  Lack of funding may delay the work.

[Tom Goddard]

Here is an update on arm64 support for ChimeraX dependencies. Formerly these were missing

Qt 5, PyQt5, ambertools, pytables, h5py, imagecodecs, matplotlib, netcdf4, scipy

Currently (Oct 18, 2021):

PyPi PyQt6 for Qt 6.2 now has a universal Mac wheel. That should also have QWebEngine support.
PySide6 does not have a PyPi arm64 wheel and I can find no discussion of arm64 support.

matplotlib 3.5.0rc1 has mac universal wheel on PyPi, made Oct 1, 2021

h5py (August 23, 2021), imagecodecs (Aug 25, 2021), netcdf4 (June 21, 2021), scipy (Aug 1, 2021) only have mac intel wheels on PyPi. pytables still does not even offer a mac intel binary wheel for python 3.9.

ambertools, I think we compile it and have not attempted it on arm64.

[Tom Goddard]

I tried PyQt6 and PyQt6-WebEngine PyPi wheels in ChimeraX. They Log and File history and all HTML widgets were broken leaving those panels blank. It spewed 10 copies per second of the following error to the shell

[28898:259:1025/172621.011291:ERROR:network_service_instance_impl.cc(330)] Network service crashed, restarting service.

A test of QtWebEngineView in the system Python 3.8 (/usr/bin/python) with PyQt6 gave the same error. Several hours of investigation revealed the QtWebEngineProcess app that Qt uses to render html was failing to start. Console crash logs show a code signing problem

Online info says with Apple Silicon unsigned apps cannot be run while on Intel cpus they can be run.

​https://eclecticlight.co/2021/01/26/when-you-dont-have-permission-to-run-an-app-on-an-m1-mac/

And another article describes how to add an adhoc signature

​https://eclecticlight.co/2019/01/17/code-signing-for-the-concerned-3-signing-an-app/

Although the codesign command failed apparently due to an obscure cache issue giving an error

goddard@Toms-Mac-mini chimerax % codesign --force --deep -s - ~/ucsf/chimerax/ChimeraX.app/Contents/lib/python3.9/site-packages/PyQt6/Qt6/lib/QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app

and the solution for that is to copy the QtWebEngineProcess.app and sign the copy.

This whole QtWebEngine problem was discussed today on the PyQt mailing list by Damien Elmes and Phil Thompson and I could have saved a half day if I had found this discussion instead of rediscovering all the problems and solutions!

The benchmark timings on my latest ChimeraX ARM64 build (Oct 26, 2021, uses PyQt6) and macOS 11.6 seem to have improved since the ones I reported 3 months ago in comment 9. So here are new timings. For Intel emulation and MBP Intel (plugged in) used Oct 24, 2021 daily build.

[Tom Goddard]

I ran the same benchmarks on the new M1 Pro CPU in a MacBook Pro 16" (MacBookPro18,1) released this week (macOS 12.0.1, 16 GBytes memory). Tested this at the SF Union Square Apple store. They did not have the M1 Max CPU on display which has twice the number of graphics cores, nor did the Stonestown Apple Store have it on display.

Summarizing the timings: The M1 Pro CPU seems about the same speed as the M1, while the GPU is twice as fast.

I made a talk for the CZI Essential Open Source Software annual meeting on porting to Apple M1 CPU

https://www.rbvi.ucsf.edu/chimerax/data/czi-nov2021/apple_m1.html

[Tom Goddard]

Native apps for the Apple M1 CPU must be signed in order to run. An adhoc signature can be used that has no certificate and the compiler adds this by default, apparently inside the executable. The codesign command reveals this, on my ARM64 development build:

codesign -dvvv ChimeraX.app
Executable=/Users/goddard/ucsf/chimerax/ChimeraX.app/Contents/MacOS/ChimeraX
Identifier=ChimeraX
Format=app bundle with Mach-O thin (arm64)

Signature=adhoc
Info.plist=not bound
TeamIdentifier=not set
Sealed Resources=none
Internal requirements=none

If I download a dmg with this adhoc signed app onto an M1 Mac I can copy the app to the Desktop but when I run it is says it is "damaged" and offers only to move it to the trash. To get it to run I can remove the HFS file system attributes from the dmg with

xattr -c chimerax.dmg

and then the extracted copy runs without any complaints, not even a warning about not being checked by Apple.

[Zach Pearson]

Since I've been tasked with the CZI grant which includes porting ChimeraX to Apple Silicon, I'm reassigning this ticket to myself and adding Tom as a CC'd party, though any comments from any person CC'd on this ticket are always welcome.

Since the last update I've whitelisted scipy and matplotlib, both now have wheels for M1.

imagecodecs, netCDF4, and tables are still troublesome.

Ambertools21 and OpenMM both supposedly have releases which support M1.

Work in progress is on ​this branch on GitHub.

[Zach Pearson]

While building ChimeraX without imagecodecs, netCDF4, and tables with the intent to release such a build is obviously not a good idea, it is possible to build (the Qt6 version of) ChimeraX on Apple Silicon currently with just those three packages excluded in prereqs/pips. Pasted below is a copy of the environment from the bug reporter, as well as the output of the Apple crash reporter after calling kill -6 on ChimeraX's pid.

That is great progress.  Most users won't use imagecodecs (reading TIFF image data), netcdf4 (reading MD trajectories?) or PyTables (reading and writing HDF5 files).  But I agree we should get those working on M1 before making it a daily build.  But it would probably be ok making it a Tech Preview build.  Will need to figure out what machine to use for builds.  I think all our M1 CPUs are laptops and the mac mini.  Maybe we should move the Mac Mini to work and use that for builds.  I don't think we should cross-compile (ie build M1 ChimeraX on an Intel machine), more trouble than it is worth.

[Zach Pearson]

I neglected to mention I had not tried compiling OpenMM 7.6 or Ambertools 20; if you have a similar opinion about those prereqs then I'm OK with a techpreview build currently, if not I will work on those Makefiles ASAP.

[Zach Pearson]

Apologies about the ambiguous wording of "just those three packages excluded", would have been better to say "just those 3 pip packages".

[goddard@…]

Yes.  Good to have a list of everything that is missing.  So Ambertools and OpenMM.  Still most users would not notice the 5 missing packages.  Still think it would be fine as a techpreview, but not as a daily build.  It is going to be painful to build those packages and you would be doing a bigger service to the community if you could get the maintainers to release an M1 version of those packages.  Might not be possible for any of them, but worth trying.

[Zach Pearson]

I'm definitely inclined to agree. In OpenMM's case they have an arm64 build on conda in version 7.7, and in ambertools's case Ambertools21 is supposed to support M1 and its mailing list archives would indicate it has been active with people reporting issues and coming up with workarounds. Famous last words, knock on wood, crossing my fingers: hopefully it won't be too needlessly complicated.

[pett]

Yes, great progress! If we make it a Tech Preview build, we would definitely want to put in the Notes section the functions that we know will not work, so that we don't get a bunch of spurious bug reports about then from people believing they're helping us. Might even want to put a warning in the log at startup, just so they don't have to refer back to the download page when they encounter a problem.

[goddard@…]

Might even go further, and in a tech preview raise a UserError if any of the missing modules are imported saying they are not yet available for Mac M1 CPU which will prevent the report a bug button from appearing.

[Zach Pearson]

Yes, that's a good idea, and I think I'll implement that. The experience of putting those kinds of warnings in would be very helpful for PyPi packaging which will run into the same kinds of heterogeneous environments.

[Zach Pearson]

Tristan made an OpenMM 7.7.0 build for Linux. I'll be using it to update OpenMM in ChimeraX.

[Tristan Croll]

Will you be putting OpenMM 7.7 into the standard daily builds as well?

Yes, I haven't made the update yet as I've been trying to wrap my head around what to do for Windows. It looks like most of the problems with OpenMM are caused by ABI incompatibilities on Linux, but I've been convincing myself it's safe to update the Windows and macOS versions. We specify a CUDA version that's not present in the filenames on OpenMM's conda repo, and I don't think they pin CUDA in their package.

We get OpenMM binaries for Mac and Windows from Anaconda

The Mac and Windows version are for specific CUDA versions.  You can see the CUDA version by clicking on the “i” icon in the distribution table since that info is not in the Anaconda file name.  See the attached image for what the anaconda table looks like.  The “I” icon is immediately to the left of each file name.

😅 What a discoverable feature that is...

Thank you!

[Tristan Croll]

They used to specify the CUDA version(s) they built against in the file names, but not any more - to find out what they'd used for 7.7 I had to expand the tarball and ldd​ OpenMMCudaCompiler.so (they built against CUDA 11.2). It's not actually strictly necessary for the user to have that specific CUDA version installed - although it does help a little with startup performance. OpenMM works out what's available at runtime and adjusts accordingly. ​

​https://github.com/PyTables/PyTables/pull/944 Tables may be getting close to an M1 build.

[Tom Goddard]

I added OpenMM 7.7.0 for Mac M1 to the build taken from conda-forge. Other platforms are still using OpenMM 7.6.0.

[Tom Goddard]

I added Intel AmberTools to the Mac M1 distribution and tested and it works. This works because AmberTools is called using subprocesses so they run using Rosetta emulation. The same is true for ffmpeg encoding movies. I tested AmberTools on an M1 ChimeraX for showing an electrostatic surface (on AMP, PubChem 66083) and it worked.

[Zach Pearson]

I converted the Conda tarball versions of netCDF4-1.5.8, imagecodecs-2022.2.22, and tables-3.7.0 -- all of which are available on arm64 macOS -- into wheels and uploaded them to the ChimeraX pre-reqs repo. I'll update our Makefiles to ensure that they install on M1 machines and then work on setting up the M1 mac Mini as a build machine. Then, we can move this project into the bugfixing stage.

[Zach Pearson]

After installing tables and netcdf4 to a developer build I discovered that some dynamic libraries were missing. They were not included in the Anaconda tarballs, so I retrieved them from /opt/homebrew/ and uploaded them to the prerequisites archive on plato, changing the extensions from .dylib to .dylib.arm64 to make it clear which platform they are for. I'll ensure correct rpath/runpath values in netcdf4 and tables' shared objects and ensure that the libraries are placed in the right spot.

[Zach Pearson]

Changes not needed because the tables search path looks first in the local Python before expanding search to /usr/lib. netcdf4's search path is pretty polluted with paths that look like they're from CI runs, however.

​This commit installs the packages. Not closing this ticket because it's about making a distribution.

[Tom Goddard]

Should not use homebrew libraries. Anaconda distributes all the needed libraries and those should be used. For instance Anaconda distributes hdf5 libraries needed by pytables

​https://anaconda.org/conda-forge/hdf5/files

[Tom Goddard]

Will try to distribute 1.4 native M1 build.

[Tom Goddard]

Will need to see if universal distribution including both Intel and Arm64 is reasonable size. This would be simpler for users than separate Intel and Arm64 builds. The download page will not be able to identify M1 Macs because Safari on M1 Mac claims to be for Intel (although it is a native M1 app). So users would have to know what kind of CPU they have.

[Zach Pearson]

So far: netcdf4, pytables, and imagecodecs were all sourced from Anaconda, but netcdf4 and pytables relied on arm64 dylibs that weren't bundled with the packages that need them. I tried using homebrew libraries, but Tom pointed out that they may not be ABI compatible, so on his suggestion we used libraries from Anaconda instead. Downloading the tarballs for the libraries and copying them over resulted in an unsigned code error, so I made an anaconda environment on my machine where I could install the packages directly from anaconda using its package manager. After copying those libs over, the errors went away, meaning we now have a testable candidate for an official M1 build of ChimeraX.

We are probably going to make a universal build, but as Tom noted in an email to me:

the Mac universal build [will] probably [require a lot of things to be] work[ed] out[:] [c]an we combine an old Intel macOS 10.14 support with new M1 macOS 11+ support?  Is notarization going to lead to new problems on M1? Can we build the Intel version on the M1 Mac Mini? ...

So I'm opening a new ticket for that effort blocking this one. Tom suggests testing the M1 build as a daily build offering when it's complete. I agree.

I think we should try to get an M1 compatible 1.4 build though, so my suggestion is to branch the 1.4 codebase twice: one release candidate branch, one M1 branch. We'll use the M1 branch sparingly, only cherry picking commits from develop which directly deal with M1 compatibility issues, so we can ensure that build is compatible with the other 1.4 builds.

[Zach Pearson]

Changing the milestone to 1.5 because we're going to either silently replace the macOS 1.4 download with a universal download or release a 1.5 download, but in either case 1.4 will come out without this ticket.

Hi all,

I was testing building ChimeraX on Essex (macOS 10.14, Mojave) and found that I could not cross-compile arm64 code. It is using Xcode 10.3, but cross-compilation was introduced in 12.2 which requires at least macOS 10.15.4, Catalina.

We can certainly test a universal build on macOS 10.14, but to build it we need either a Catalina machine or the M1 Mac. In the event that ChimeraX built on the M1 Mac doesn’t work on 10.14, should we drop support for it since Apple is no longer supporting it?

— Zach

[Tom Goddard]

Our usual rule has been to support at least the last 3 macOS versions, which would be 12, 11, 10.15. But we don't drop support for older ones unless there is a good reason.

Looks like 10.15 and newer comprises 85% of macOS systems with 5% at 10.14 and 5% at 10.13

​https://gs.statcounter.com/os-version-market-share/macos/desktop/worldwide

Can an M1 Mac cross-compile for Intel? On Mac we set MACOSX_DEPLOYMENT_TARGET = 10.13 in the build_tools repository (hosted on plato) in build_macosx.sh. I am a bit puzzled why our download page says 10.14 while our build scripts say they target 10.13.

[Zach Pearson]

Yes, M1 Macs can cross-compile (so can Intel Macs with Catalina or newer). I tested an M1 universal build on Essex built on my M1 laptop, but it complained that it couldn't recognize some loader instruction (it got as far as trying to import the arrays shared object, then mach complained). However, it may be that if I set MACOSX_DEPLOYMENT_TARGET before building, it may produce code that Mojave can run. I'll try it again asap.

[Tom Goddard]

The commercial PyQt6 wheels are not working on Mac ARM64, ticket #6669. Won't be able to make a Mac ARM64 distribution until that is fixed.

[Tom Goddard]

I added a build_mac_arm64.sh script to our build_tools git repository that builds the Mac ARM64 ChimeraX on euclid.cgl.ucsf.edu and I tested running it as a techpreview build. I used PyPi PyQt instead of our licensed PyQt wheels due to bug #6669. ChimeraX built but notarization failed apparently because the build machine needs some Apple notarization keychain entry. Here is the notarization error

+ cd ..
+ /usr/bin/python3 macosx_package/notarize.py everything -a chimerax/ChimeraX_techpreview.app -d chimerax.dm\
g -v -v -v

n']
stderr:
security: SecKeychainUnlock /Users/chimera/Library/Keychains/codesign.keychain: The specified keychain could\
 not be found.

ERROR IN NOTARIZATION
+ echo 'ERROR IN NOTARIZATION'

I will try again once I find out how to get the keychain entry. Probably Eric knows that since it must be setup on his desktop machine essex.cgl.ucsf.edu which builds the Intel Mac ChimeraX dailies.

We might document a couple other steps I had to do to setup a new daily build machine. It needed to be able to ssh to plato without a password to get the PyQt wheels (so put ssh key on plato chimera account). A ChimeraX GitHub account (I used mine) needed to add the the euclid chimera ssh key so it can git clone the chimerax repository with the git@… protocol. And the notarization script needed a PyPi package called "lief" installed on the system python, and that package needs cmake to build. Also the build machine needs to be set to not sleep, so the cron job can connect to it. I did these 4 steps.

[Tom Goddard]

The next steps are

1) Put the Apple notarization key on the euclid chimera account keychain.

2) Fix the PyQt licensed wheels on plato for Mac. There are only universal PyQt6 6.3.1 Mac wheels on plato (PyQt6_commercial-6.3.1-cp37-abi3-macosx_10_14_universal2.whl, PyQt6_WebEngine_commercial-6.3.1-cp37-abi3-macosx_10_14_universal2.whl) and they work on Intel. So somehow the PyQt license handling for that wheel is working for Intel Mac but not ARM64 Mac. Ticket #6669.

3) Enable daily techpreview builds by adding shell command "./build_chimerax.sh -b techpreview -p mac_arm64" to the daily_chimerax_build script in the build_tools repository.

4) Check that the download page is able to show this techpreview. Probably needs adding the mac_arm64 platform to the download page script.

[Tom Goddard]

I've resolved the problems except the PyQt commercial wheels do not work on Mac arm64 so I've contacted Riverbank support to fix that. ChimeraX ticket #6669.

I tested building the techpreview (with PyPi PyQt), notarizing it, and put it on the preview download web page, downloaded it and tested. Everything working. It will not be part of the nightly builds until the commercial PyQt wheels work.

Here are steps that were needed to get the techpreview builds working.

1) Notarization. I copied the codesign.keychain and codesign.keychain-db files from essex (Intel Mac build machine) ~/Library/Keychains. Also had to add that keychain in the Mac Keychains app. Then notarization failed due to missing timestamps which is a frequent problem we have on Intel Mac too. Investigation suggests the timestamp issue is UCSF firewall problems and I made a ChimeraX ticket for that #7209. By building a couple times I got past the timestamp error. Notarization still failed because a dozen .o and .a (archive) files did not get signed because our notarization.py script did not recognize those as MachO binaries. The .o problem was just an omission in our script. The .a problem seems a bug in the lief PyPi package our script uses to identify binaries. I worked around the lief bug by checking for ".a" suffixes. Then the notarization completed successfully.

2) Download page. I added a mac_arm64 build platform to our update_release_info.py script and made the download page use it. This required improving our download page javascript which is relutil-1.2.2.js to handle 2 mac platforms. Also there is a bug in the download.html page where it will not show techpreview builds if SHOW_CANDIDATES=true in that page's javascript and there are no candidate releases because that generates an error and it then never considers techpreview releases. For now we can just set SHOW_CANDIDATES=false, but this bug needs to be fixed. I've left SHOW_CANDIDATES=true so the techpreview for Mac M1 will not be shown since it is using GPL PyQt. Once we get the correct PyQt we can change the download page so the techpreview appears.

[Tom Goddard]

Currently techpreview Mac M1 build is only waiting for Phil Thompson to fix PyQt6 commercial wheels. Phil says he will receive Mac M1 hardware on July 6, 2022 and it may take some days to fix the wheels.

[Tom Goddard]

I made a separate ticket to investigate the difficulties of making a universal Mac ChimeraX that contains both Intel and ARM64 binaries, ticket #7222

[Tom Goddard]

Phil Thompson found the PyQt6 problem, invalid code signature, and it should be easy to work around.

Tom,

I've found the problem. When you download your commercial wheel it is 'licensed' to you on the fly by updating the QtCore.abi.so file with your licensing information. This process invalidates the code signature for arm64 binaries (Intel binaries don't care).

The workaround is to resign the QtCore.abi.so file yourself after installing the wheel...

codesign -s - /path/to/site-packages/PyQt6/QtCore.abi.so

I need to have a think as to the best way to fix this properly.

Regards,
Phil

Tom,

The next snapshot will have the license check removed. This is the only way to fix the problem until I can sign macOS binaries on a Linux system.

Phil

[Tom Goddard]

I made our prereqs/PyQt makefile re-codesign the QtCore.abi3.so library. Take this out once Phil Thompson provides a fix. Phil says the PyQt 6.3.2 release will not need the codesigning.

[Tom Goddard]

Added the Mac M1 build to the download page as a technology preview and made the daily build script build it every night.

The build targets macOS 11 (using MACOSX_DEPLOYMENT_TARGET=11.0) but I have only tested on macOS 12. Don't have any macOS 11 machine so we will have to see if any users report a problem with macOS 11.

Used LZMA compression producing a small Mac M1 dmg file of only 250 Mbytes vs 400 Mbytes for Intel Mac with zlib compression. The LZMA compression is only available on macOS 10.15 and above and currently we support macOS 10.14 on Intel. Ticket #7274

[Tom Goddard]

The PyQt6 6.3.1 commercial wheel from Riverbank now works on Mac M1 without re-codesigning it. I've taken out the recodesigning from prereqs/PyQt/Makefile.wheel.qt6.

Tom,

I've now fixed the root cause properly. You should be able to re-download the v6.3.1 wheel and it should install and run.

[Tom Goddard]

The Mac M1 techpreview build had 103 downloads from July 21-29, 2022 from unique IP addresses according to our web server logs.

[tic20@…]

So it turns out that switching FFT libraries wasn't quite as horrible as I thought it would be. A bit of fumbling around in the dark (because it seems that nobody, anywhere, ever seems to feel it necessary to properly document an FFT library), but after a few hours of effort I'm now running happily with PocketFFT. Performance seems very similar to the MKL version, and as an added bonus the wheel file size is reduced 4-5 fold (to ~7 MB). So that's probably the biggest roadblock to a native Apple Silicon ISOLDE build out of the way.

Comment:

 Supporting Apple Silicon will take a bit of work for me, I think. The big
 stumbling block will be the Intel MKL library I'm using to replace FFTW2
 in Clipper - as far as I understand, the MKL is firmly tied to x86_64
 architecture. So I'd have to find and integrate a replacement, which will
 take a fair bit of work. Not impossible, but far from trivial.

Glad to hear you have an FFT solution for Mac ARM.

Do you need a Mac ARM build machine? We could try to give you ssh access to our Mac ARM ChimeraX build machine (euclid.cgl.ucsf.edu). It is some trouble because the UCSF firewall does not allow ssh into UCSF machines. We would have to give you access to the CGL VPN or get UCSF IT to make a security exemption so ssh is possible.

[Tristan Croll]

No problem there - I have a shiny new MacBook Pro to play with! Any tips
would be welcomed, though.

The Mac M1 doesn't require any compiler flag changes.  There is the -arch flag which lets you build both ARM and Intel binaries at the same time although you probably will not need that kind of universal build.  We have a Mac M1 ChimeraX version at the bottom of the download page under Technology Preview and plan to make daily builds in coming months and a native Mac M1 release of ChimeraX 1.5 around the end of this year.

[goddard@…]

Building on Mac ARM should use MACOSX_DEPLOYMENT_TARGET=11.0.  I don't know exactly how you build so I'm not sure if that will be used automatically because the Mac ARM distributed build used that setting, or if you need to change some Makefile or bundle_builder code.

[Tristan Croll]

I have it set in the Makefile (to 10.13 because I understand that's the
current standard that ChimeraX adheres to). I don't think bundle_builder
sets this anywhere (perhaps it should?)... I added it to the Makefile
quite some time back in response to a user complaint (I updated my OS, and
as a result one of my release builds was no longer backward-compatible).
There's a ticket somewhere back in Trac - that's where I learned of the
existence of that flag, thanks to Greg.

The more I think about it, the more I think it might be sensible if
bundle_builder automatically set MACOSX_DEPLOYMENT_TARGET to its preferred
value (perhaps only doing so if it's not already set, to accommodate people
who want to be doing something special). Otherwise my code needs to figure
out whether I'm building against Intel or ARM ChimeraX and set it
accordingly (unless you plan to go to a 11.0 minimum across the board?).
