[chimerax-users] ChimeraX on Mac

[Elaine Meng]

Hi Lisa,
"does not work" is not much information.... do you mean that it doesn't start at all? 

I have a laptop running OS 10.15.7 and it can run ChimeraX 1.1, 1.2.5, 1.3, and 1.4 releases just fine. I tried them all today. The first time I started 1.3 it gave some orange warning messages and suggested I should update to 1.4, but I could ignore those and keep using it without problems.  It may have been related to a bundle I installed from the Toolshed, I'm not sure. The second time I started 1.3, there were no warning messages.  

My only guess is that something weird got stored in your preferences, or previous files list, or other settings that interferes with the startup, but I don't know.  There are several different settings files so I hesitate to say to delete them when we don't even know whether they (or which one) might be causing the problem.  On mac these files are written into ~/Library/ApplicationSupport/ChimeraX/ where "~" is your home directory, e.g. /Users/meng in my case.

One idea to try to get some information is to try to start ChimeraX from Terminal, e.g. if installed as /Applications/ChimeraX-1.4 then you could type this in the Terminal window to start it

/Applications/ChimeraX-1.4.app/Contents/macOS/ChimeraX

...and see if any error messages appear in the Terminal window.  

I hope this helps,
Elaine

So I removed that version and installed the newest version, however, it does not open. There is no error message so I am a bit lost at what I can do to resolve this issue. The macOS is 10.15.7.
