[Chimera-users] Select multiple files and open in the same instance

[Elaine Meng]

Hi Ahmad,
I'm guessing you are using MacOS Catalina, for which this is a known problem.  Sorry, there is no Chimera setting to control it.  One possibility is to use ChimeraX instead, which does not have this problem, but it depends on which tools/features you are using.  ChimeraX has the same map fitting and many other things as Chimera.  Some  currently missing features are listed in the ChimeraX download page.

This separate-instance problem was mentioned in earlier posts, for example:

I hope this helps,
Elaine
