Yeah, it's frustrating for sure, but I think I speak for a lot of us when I say we really appreciate your commitment to supporting Blender on Mac despite all of Apple's software issues.

Thank you for your hard work on this. Unfortunately, commit rB680c7209ecf7 hasn't resolved the issue as of today's build b5d87f802806. Hair particle behavior in the viewport remains the same, as described above.

On a whim, I decided to try today's build (08ab09cf04d9) on my wife's computer (an older Apple laptop), and it seems to work properly there, but it is still broken on my machine.

Still the same issue in the latest build, except for the last bullet point above (Blender no longer crashes if there are 0 hair particles).

I'm not sure how you accomplished that, since Blender won't allow me to enter particle edit mode with the object visibility turned off.

Can also reproduce this bug following the above steps using the latest build (3c3d80ea22af). The crash occurs as soon as particle edit mode is selected from the drop-down menu.

The terminal output I got was simply:

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