Hi Marcel,
Thank you for building the release candidate. I just used the squeak.cog.spur_macos64x64 VM with the latest Cuis image for several hours. When I tried to save and quit the VM it crashed, see attachment. It seems to have saved the image correctly before the crash.
I used OSProcess extensively to call md5 to calculate file hashes. I ran into a lot of OSProcess errors. Maybe the crash has something to do with this.
Cheers,
Bernhard
