[Chimera-users] Sudden Chimera issues with OSX Mojave?

Hi Neil,

   If macOS didn't change and Chimera didn't change but Chimera is crashing now there are two possibilities I can think of.  One is that something in Chimera preferences got set that is causing the problem.  You could rename your ~/.chimera/preferences file so Chimera starts with default preferences to test that idea.  One other possibility since you mention that changing the setting about what directory the Open dialog starts in has an effect -- maybe you have external drives or network mounted drives on this computer and those extra file systems somehow are causing the crashes when trying to open a file in Chimera.

We have two new identical systems that were running perfectly as recently as 48 hours ago, but now Chimera is constantly crashing whenever we do something as trivial as File>Open or if we attempt to save a map.
