Broken: version: 3.1.0, branch: master, commit date: 2022-03-08 18:16, hash: c77597cd0e
Worked: 3.0
Caused by 5b299e5999 (@RoyTheKoi found this)

Short description of error
Using hair particles freezes entire MacOS, the entire laptop becomes unresponsive and hard reset is required.
The problem occurs when hair needs to be displayed in a viewport (if it's hidden in viewport, the system does NOT crash when rendering hair in Cycles.

Exact steps for others to reproduce the error

Open attached .blend file and turn on the particle in viewport
or
Add ParticleSystem, Hair.
Increase the number of particles (over 10 000 will always break it).
The computer will freeze (please note the system info).

Hi, thanks for the report.
I don't get any freeze when I turn on viewport visibility for hairs.
Can you check with factory reset?: {nav File > Defaults > Load Factory Settings}

Operating system : Windows-10-10.0.18362-SP0 64 Bits

Hi Pratik,
Yes it still happens, and let me give you more details.
Sometimes, Blender will crash without freezing MacOS.
It seems to be the problem with the GPU, because often the crash
will start by GPU glitching (screen artifacts), and then either
the system will frieze or Blender will show up normally again
for a moment and then crash.
Notice that when using Cycles rendering in viewport, it does not crash.
It only crashes when using Shaded or Wireframe views.
Hope this helps, let me know if you need any more information.
Thanks

I cannot reproduce the problem.
It reminds me of #83199 (Blender crashes when adding a particle system to a mesh object and switching the type to Hair)

This may have something to do with the workaround to "transform feedback" on Macs. Since "transform feedback" doesn't work on some Macs (See #58489, #60171).

Thanks for checking this. Please note that the error does not appear with low hair count, more less below 10 000. Also I have an AMD card, not M1, and it all worked fine before 3.1 - if all this info can help troubleshoot

I experienced this same issue while testing the new hair curves in 3.2 Alpha. The entire OS freezes and only a hard reset fixes things. For me the freezes occur whenever >5000 hair curves are present in solid view (workbench?), not in Cycles.

I can reproduce the problem with the provided blend file also.

Looks like it works correctly on M1 devices, but not on Intel/AMD combo. I tried it on my older MacBook Pro, which has Radeon 560x card, and it did not crash but I could not even get particles to show in the viewport (in none of the shading modes).

AMD Radeon Pro 5500M 8 GB
Intel UHD Graphics 630 1536 MB

I was following some carpet tutorials and when using the particle system my entire system crashed. Now I can't open that same file again with the risk of the OS crashing entirely too.

Tested on Blender 3.1.2, using Cycles on GPU

We cannot reproduce it also on his system. With the steps provided in the description.
As no developer was able to reproduce it we will lower the priority until there is more information available and developers are able to reproduce it.

@ThomasDinges as two users are able to confirm it doesn't mean that we have all the information to reproduce or fix this issue and this ticket can move to on the working board of a developer; It should still be triaged. Especially for platform issues they need to be reproducable, before the GPU team is able to do anything with it, or there should be a very clear stacktrace.

Running the test file on 3.1.2, I found that Blender quits after ~30 seconds of freezing the OS instead of requiring a hard reset. Still, no crash log is saved.
The only information I was able to get was the following output from the terminal:

{F13719967}Hey all, this is basically what I've been faced with as well.
TL;DR: no problems until I started trying out the new hair curves system last night. Now I'm getting full system crash, even with no viewport shading at all. (UPDATE: I reproduced and attached system crash info)

Specs:
macOS Monterey 12.6 (most up to date as of today)
2019 16-inch MacBook Pro
2.6 GHz 6-core Intel Core i7
16 GB 2667 MHz DDR4
AMD Radeon Pro 5300M 4GB
Intel UHD Graphics 630 1536 MB

Which are specs almost identical to another poster here. So in my case I'm running the latest Blender version 3.3.1 (which I have been since it came out) and was having no real issues. I did a benchmark test just to see which of the graphics I should use in cycles and since for the first time Metal is supported, I have for the first time started using GPU compute which has been largely successful. The difference maybe slight, but I figured I would try using GPU. Anyways here's what happened last night:

Using the new hair curves system, seems to be what has caused the problem. I haven't really dealt with the whole entire macOS freezing up before but that's been happening now. I am forced to do a hard reset. When I have tried to reopen that same file the same thing happens (as indicated by another user here).

I don't know if this might be helpful but I found a workaround at least to prevent the crashing and be able to load the hair on MacOS without the crashing happening.

You have to hide the particles from the realtime viewport on the particles tab, if you do so, the project should load and Blender will not crash, Save, and then reopen the project.
Go onto the Viewport Shading and wait for the materials to load, then you can manually reveal the particles on the viewport again, this should load the particles correctly and not freeze the system and crash the program.

This issue appears to happen on start when Blender attempts to load everything at once: Materials, geometry and particles, this has resolved the issue for me so far and I can finally see and edit my hair particles without crashing.

However you have to hide the particles from the viewport realtime before closing blender, otherwise on the next open it will freeze again

Adding to the pile on this issue I guess? Similar system specs, similar issue; Blender crashes while using new hair system in eevee viewport, File fails to open or crashes system every time after that. Blender files from other sources which use new hair features also crash Blender.
