[Chimera-users] Click-and-drag selection still not working for chimera in Mac OSX....any plans for improvement

[Elaine Meng]

Hi Carmen,
I also have this issue, but I’d never noticed it since I never use drag-select!!!  I have a mid-2015 MacBook Pro with Intel processor and graphics, and can confirm that selection by dragging a rectangle over sticks/ribbon does not work even at OS 10.13.6.

As mentioned, however, I never use drag-select, as it is imprecise and I am uncoordinated.  I just use Ctrl-click (+ Shift to add to selection) to click on atoms and bonds directly, and then press keyboard up arrow to promote  atoms/bonds -> residues -> (etc.) as described here:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/selection.html#expandselect>

I hope this helps,
Elaine

Unfortunately Apple abandoned effort on the OpenGL graphics library years ago in favor inventing their own new graphics library called Metal.  Chimera has to work on Windows and Linux in addition to Mac so we do not use the Apple-only Metal library.  While OpenGL continues to work on Mac computers, I would not expect Apple to fix any OpenGL graphics driver bugs.
