Hi Arwid,<br>
<br>
Yes Chimera 1.4 released in December of 2009 is the last Chimera
version that is compatible with Mac OS 10.4, both PPC and Intel. This
is mentioned in the News column on the Chimera web page (Dec 3, 2009).
We will have a Chimera 1.4.1 release to fix some bugs around the end of
this month that will work with Mac OS 10.4. The Chimera package you
mentioned is our daily development build version 1.5 and was built
using Mac OS 10.5.<br>
<br>
We are updating Chimera to use the new Mac Tk windowing library based
on Cocoa so that we can provide a 64-bit version of Chimera for users
with large data sets. Tk Cocoa only runs on Mac OS 10.5 and later.
The older Mac Tk using the Mac Carbon library (32-bit only) will no
longer be maintained by Daniel Steffen the main Mac Tk developer. We
are not yet certain if both 32-bit and 64-bit versions of Mac Chimera
1.5 will use Tk Cocoa. The 64-bit has to, and we would like the 32-bit
version to use the same Tk library. Whether we use the old Tk Carbon
for 32-bit Chimera depends on whether we encounter any serious
deficiencies in Tk Cocoa. So far it looks like Tk Cocoa will work for
both 32-bit and 64-bit Chimera on the Mac.<br>
<br>
A second reason for requiring Mac OS 10.5 for future Chimera versions
is that it is trouble for us to keep very old computers in the lab. We
have two Mac OS 10.4 systems (PPC and Intel) in our lab that are only
used for Chimera builds. We would like to retire those old systems.
While it is possible to build on Mac OS 10.5 a binary that will run on
Mac OS 10.4 we have tested that and encountered problems.<br>
