Hello, my experience is the same as Talin. Since Blender 3 (and now using 3.2.1) crashes are quite rare. Only if I push a render too far but that's expected.
I've run Blender smoothly on my iMac Late 2015 (AMD Radeon R9 390M) and now my "new" iMac 2020 (AMD Radeon Pro 5700 XT 16 GB).
All good !
Thank you Blender Team for your hard work :-)

I have the exact same iMac as above and also a macbook Pro 13 Mid 2014.
Since I've tried 2.90, 2.91 and 2.92, Blender crashed so often and totally randomly like when:

• opening the software
• using any tool.
• an-hiding a Collection
• switching back from another software to Blender
• while rendering.
• anything you can think about.
