Mac keeps crashing when running works

Support
1

Hi Chris,

My mac has been crashing unpredictably whilst running mworks. Sometimes it goes for days without and then it crashes relatively fast one after the other.

I am not sure if there is a background process starting and then mworks doesn’t get enough RAM or whatever, or what this could be.

I’m still quite new to macs also. Do you have hints how to proceed with diagnosis or what I could try setting-wise to maybe combat this?

I have saved the report that apple wanted to have saved, see below

Thanks!

Alina

Hi Alina,

If the WindowServer process is locking up or crashing, this suggests an issue with the graphics hardware and/or drivers. Searching online, I find many similar issues, though I don’t see any common cause or resolution.

It looks like you’re running macOS Big Sur (version 11) but not the latest release (11.6.8). Maybe the first thing to try would be updating macOS, in case 11.6.8 includes a fix for this issue? If that doesn’t help, you could try upgrading to the most recent macOS release (Monterey, version 12).

When the crashes happened, did you have an external display connected? If so, it’s possible that an issue with the display adaptor is causing the problem. If you can, try using only the built-in display for a while and see if that helps.

Cheers,
Chris

Hi Alina,

I will try your suggested steps and get back to you. This is a old trashcan style mac, there are exclusively external displays. And I need them to run my experiments of course.

Any updates on this? Is your Mac Pro continuing to crash periodically?

Thanks,
Chris

I ran the simple update you suggested as the first step I think and so far no more crashes.

Probably I should update to the newest macOS? Is that compatible with mworks (which version?)

Thanks!

Hi Alina,

Great!

If macOS 11 is working for you, there’s no need to upgrade right now. But if you do move to macOS 12, you should use either MWorks 0.11 (the latest release) or a nightly build.

Cheers,
Chris
