Hi ,
I was happily using brew installed pymol 1.7.6 on my Macbook Pro (running
OSX Sierra) and then had a hardware failure.
I switched computers to MacBook Air running the same version of OSX (Sierra
10.12.2 ) and Xquartz (2.7.11) and now pymol ( and coot and other X11 using
applications) refuses to function with smooth molecule rotation on even a
30kDa protein.
I know the Macbook Airs are not that underpowered and am wondering how to
troubleshoot the lack of smooth rotation.
I have tried:
Reinstalling pymol (now running 1.8)
Reinstalling Xquartz ( still running 2.7.11)
Using an external mouse
ANd still have rotation that gets stuck. It starts rotating smoothly and
then locks up. I can see the Mac red/yello/green circles go gray like X11
is sleeping when this happens . It resumes after a second and rotation
cotinues .
Looking for others having the same issue does not pull up anything. I can
get smooth rotation in Chimera and Cuemol2 on this new laptop so it seems
to be a Pymol(Coot) X11/Xquartz issue that I dont know how to fix.
Any ideas or help would be greatly appreciated since its two weeks till my
faithful computer returns from a hardware fix.
Thanks
Hari
