I test the G3 and get crashes all the time. I have a macBook Pro 2019, latest OS, Glyphs are also with the cut edge updates and the 2nd works fine. But 3 is not. There are 2 scenarious - the program crashes itself or the OS crashes, so a need to reboot comp, caused by Finder hungings. I tried to work with files of 2nd version and started from scratch — nothing. The problem is that I cannot understand at what point this happens, there are no special cases.
Is it so unlucky for me? Or is the product still damp? Maybe it makes sense to wait?
What version do you use specifically (the four digit number starting with ‘30’)?
Can you send some crash reports (the one that comes up when you restart the app)?
Do you have any plugins installed?
The it crashes, there should be the crash dialog from the system. It has a “Details” button. Can you click that and send me the first few pages of that text?
