Big Sur Mac Crash 4 times in the last 6 hours - 2 no-report and 2 reports

With the upgrade to Big Sur 11.0.1, my iMac Retina 4K 6-core intel core i7 has become highly unstable. Its crashed 4 times in the last 6 hours. 2 times it crashed with no report. The last 2 times I received a report. The odd thing is one time it crashed when I wasn't even using the computer. This time it crashed with Android studio open, safari open, the app store open, and amazon music playing. Otherwise, I wasn't using the computer.

I used to brag to my friends how stable and secure MacOS was. Not quite sure with this release.

Any suggestions?

Same issue here, just made a clean install not sure what it could be but seems to me that every time it happens time machine is running.

Same here. Here's what I got:

I am also having the same Problem after updating to Big Sur. I was advised by Apple support to reformat my device. After reading the details here not sure whether that would solve my problem or not. Hopefully Apple solves this soon. Frustrated.

PROBLEM.... SORT OF FIXED/REDUCED, Been having this problem just like everyone, noticed that it only crashed when things were idle, and once when it looked like it was going to crash I started to move the mouse and it came bace from the edge. I got the idea to try a "Mouse jiggle USB port mouse mover" which I turn on anytime I am away from my screen (The Jiggler I have has a built in power switch) and for the last 2 months it has not kernel panicked once when the Jiggler was on. This proves that it is a problem when things are Idle and Apple needs to fix this.

Confirming that this still crashes on Big Sur 11.5.2 (20G95) with the following log:

It's really hard to continue doing work when this keeps happening. @appledevs a little help here would be great

My MacBook Pro 13" M1 (Big Sur 11.5.2 (20G95)) crashed several times already.

One of the crash reports with error:

IOSurface creation failed with size [844 x 128]. If size looks sane, this is likely due to an IOSurface leak and system IOSurface limit reached.

I'm afraid I have no answer, but also experiencing the same thing.

I have a MacPro 6,1 (I know, pretty old...) and it crashes with the panic multiple times a day (only 1 today so far!)

"panic(cpu 2 caller 0xffffff80149f9a25): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds"

I wanted to mention some basic things I've tried:

  • Disconnecting external HDD
  • Disconnecting my LG ultra-wide monitor
  • Disconnecting my (oooold) DELL monitor
  • Changing fan speeds using TGPro (felt like it was doing something useful, but I wasn't convinced it made a difference)
  • Just using 1 app at a time (e.g. Chrome, Outlook)

I can spend hours editing photos on Lightroom or doing sound Editing on Cubase and it can be fine. It feels random. As much as I want to blame the Microsoft Products I've got, it seems to crash when I'm dragging something, or switching desktop a lot, especially if I'm doing lots of things at once. It feels like it can't keep up, even thought the machine is very nippy generally. The screen will freeze but the mouse will continue to work for 30 seconds, then everything freezes for the remaining 90 seconds until it resets itself.

Feels like GPU issue, but I'm no expert. So much for 2 graphics cards being useful huh?

I'm waiting for the new macs to come out, but scared that this is an OS problem and it will continue! I didn't have this problem on my 5,1 Mac and seriously considering going back to it.

Good luck to all of you (us) in getting over this ridiculous unreliability of what was a much loved brand for me.

I get crashes like this every morning since I updated to Big Sur, any time that I’m not at my machine and actively using it for a few hours (or less). Happens regardless of whether I have no apps open at all, lots of apps open, active tasks running / processing data, or even while actively listening to music on my ps4 from mac’s media server.

Note that I upgraded my system from High Sierra to Big Sur a few weeks ago, and had anticipated issues... but OS back to back crashing & rebooting all by itself whenever left unattended is quite the headache. A reboot may re-open all your apps and windows, but CPU intensive tasks/jobs are aborted and have to be restarted all over again -- days of progress lost at times;

I migrated to Apple from PC's over 25 years ago because I needed a stable system...

Crash report after reboot:

I have the same issue. Macbook shuts down at night.

MacBook Pro (16-inch, 2019)

Sending crash reports all the time..

I have a brand new 2021 iMac that I bought in March of this year (21). This has been happening to me since two months after buying this iMac. I can be running photoshop, after effects, premiere and audition and it crashes. I could be writing an email with nothing else open and it crashes. I could be scrolling thru spotify and it crashes. There is not a program or instance that causes this to crash and I've reiterated this to Apple and they still don't help. I even took it to the Apple store twice for them to do stress testing on it and they say the hardware checks out just fine, but that's clearly not the case when this happens.

I even get a variety of crash reports once it finally reboots, I get the same one from time to time but most of the time it's always something different. I'm beyond frustrated and was on the phone with six different people last Friday for ~90 minutes. Even with Apple Care+ they said there's only a 14 day policy for getting a completely new system, it's total ******** and am beyond frustrated that they have hardly extended out an arm to get this NEW system replaced.

Not an answer, but just noting - as of Nov 7th, 2021, I am also seeing the same issue:

Happening on my mid-2014 MacBook Pro.

panic(cpu 2 caller 0xffffff80165fda25): userspace watchdog timeout: no successful checkins from com.apple.logd in 120 seconds service returned not alive with context : unresponsive dispatch queue(s): com.apple.firehose.io-wl service: com.apple.logd, total successful checkins since load (650 seconds ago): 54, last successful checkin: 120 seconds ago service: com.apple.WindowServer, total successful checkins since load (620 seconds ago): 62, last successful checkin: 0 seconds ago

MacOS Big Sur 11.6.1

This also started appearing on a Mac mini 2018 that is being used as a fileserver. It might coincide with the upgrade to macOS 11.6 or 11.6.1. Every few weeks to just days I find the machine had restarted with the all too familiar crash report:

userspace watchdog timeout: no successful checkins from com.apple.remoted in 180 seconds
[...]

There were no such issues with 10.15; connected peripherals have not changed.

Big Sur Mac Crash 4 times in the last 6 hours - 2 no-report and 2 reports
