Hi all, A fix for the non-showing buttons problem on MacOS Mojave (10.14) is now in the Chimera daily build and the 1.13.1 release candidate. If you encounter any problems with the new version please use Chimera’s Help→Report A Bug to let us know about them. Note that the fixed version only runs on Mac OS 10.10 or later, whereas the previous version also ran on 10.8 and 10.9. —Eric Eric Pettersen UCSF Computer Graphics Lab
