MacOS Catalina 10.15.4 Crashes

What peripherals do you normally have connected and how?

I am having the same problem as well. I am using the computer and all of the sudden, it shuts down and restarts.

iMac 2017,  27-inch iMac with Retina 5K display

Running Mac OS X 10.15.4

SAME. iMAC 2014 5K started rebooting when idle (after screensaver has been on for a while). This never happened before - it just started immediately after the 10.15.4 update. Never had Norton, never had Facebook, so those can be ruled out. Seems like a bad upgrade for some people.

Ran diagnostics data capture tool sent to me by Apple Specialist. Data was gathered then uploaded to their server in order to be transmitted to Engineering for analysis. No resolution or workaround provided at this time.

To avoid potential data loss or SSD wear-and-tear due to the unexpected reboots, I'll be shutting my system down every night after I'm done working until Apple provides a fix.

My fairly new MBP 16inch has been crashing 3-4 times a say since 10.15.4 was totally fine before.

I keep submitting the reports.

it also seems to crash durning power up, i press the power button and it does a double reboot.

this is probably from sleep mode. i have disabled the power NAP to, PLUS i have installed beta 10.15.5 and its still happening.

I hope they get it fixed soon

I am not re-installing my mac !!

Cheers

I have the same issue on an MacBook Pro 16', could be because I have a dock connected? or because I have an external disk connected (ssd)? I will try to leave the MacBook go in screen saver mode without dock and disk connected....

I also try to deselect "put hard disk to sleep when possible"

If I will try an "acceptable" solution I will share it....

I just updated to 10.15.5 thinking that this issue would be fixed. But i am still facing the same issue. When ever some kind of performance is required from the MAC it starts crashing the apps that are running, kindof a domino effect.

I am mostly using the macbook for coding ios apps. Xcode crashes when ever heavy operations is being done, the fan would start spinning in. speed and ultimately everything will crash. If i kill the processes manually when ever i start hearing the fan speed up, then the apps wont crash.

It happens to me on 10.15.5 (MBP 16", i9, 16GB), using VSCode. I've noticed that each session before a panic, lasts around 45 minutes. When the panic occurs, the machine will freeze for about 15 seconds, the screen will turn black and the fans will kick in at 100%. It'll then reboot after another 10 seconds or so.

day two update, so my new logic board came with 10.15.1, so i bravely updated to 10.15.5. so far so good, Except with chrome !! with GPU acceleration enable in chrome, some websites are corrupted with lines !! yet another problem, ! perhaps i should have stayed with 10.15.1

its only a few sites, other people with MPB 16 have reported this, the solution is to turn off GPU acceleration in chrome !!

anyone else seen this, ?

Unfortunately, mine just crashed in sleep again with the same error complaining about the following driver: Suspected bundle: com.apple.driver.AppleBCMWLANCore

Same issue, since the 10.15.4 update. My MacBook Pro (16") has rebooted 4 times in past 10 days since upgrade, usually after sitting idle for several minutes/hours.

prior to the upgrade, unexpected reboot "might" have occurred twice since I bought this laptop a few months ago.

My MAC PC has been locking in the morning following recent update Catalina 10.15.4. Cannot get rid of spinning circle until I unplug system and allow it to rest. Turn back on and allow it to come up. Had to do this twice today. Is there a solution.

I'm getting the same error message, but I'm in Mojave (10.14.6). This crash has been happening off and on for the past couple of months. This is an iMac I got this past August, so barely six months old, and it's been doing this for at least half that time.

I do have Norton running on it, so it might be a Norton issue for me. It seems to restart a lot overnight. When it restarts when I'm using it, it's happened most often when I'm searching for something in Spotlight or using the search feature trying to track down an email in the Mac Mail. It just blinks out in a scary way, like someone pulled the plug.

April 9, 2020: Got notification of update to original 10.15.4. On restart, system stops installing software. I waited about 45 minutes, then unplugged computer. Plugged it back in and computer came up. I am getting notice to install the software update but will not. If system updates on its own, I'll follow same procedure. Sad face.

This is not the problem we’ve been discussing here. Our issue has been on Macs resetting after/during sleep, after the macOS 10.15.4 update. What you have posted here doesn’t seem to have anything to do with that.
