I can not reproduce this issue with a build from today, could you retry with a recent build?

Tested today on same system with todays build and still have the same crash.

I've been experiencing the same issue, including with today's build.

Could you guys run blender with --debug-gpu and attach the output you get when it crashes (as a file).

You can also try to run blender with --debug-gpu-force-workarounds and see if that helps.

The terminal output I got was simply:

Writing: /tmp/blender.crash.txt
Segmentation fault: 11

Interestingly though, with --debug-gpu enabled, doing anything with hair particles yielded a whole bunch of:

I believe macOS particle drawing crashes were fixed, if it's still an issue we can reopen the report.
