MacOS Catalina 10.15.4 Crashes

Replying to my earlier comment: Since I have quit playing a particular game in Facebook, I've no longer experienced any crashes. It's a game that "squeaked" by an earlier OS update, squeaking meaning there were several hesitations in loading the flash drive, but eventually it would load. Just a thought......

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.

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.

Save your energy, been there, done that. To ALL that's having this problem, here's what I've already done with my 16" 2019 MacBook Pro to troubleshoot/resolve this issue:

1.) Checked Disk Drive via Disk Utility First Aid (from Recovery Partition)

2.) Reinstalled macOS from Recovery Partition

3.) Worked with Apple 1st-line support, ran hardware diagnostics (all components pass)

4.) Reset SMC and PRAM/NVRAM

5.) Total erase of drive and re-install of macOS. Recovered data from backup and manually re-installed my Apps

6.) Upgraded macOS 10.15.4 With Supplemental Update released within last 24 hours

I did these things, in the order listed, and still the idle-screensaver-reboot issue reoccured. My conclusion - This problem is rooted in the bowels of the 10.15.4 update. It is NOT triggered by any single App or hardware component (ex. I use a 4K and 5K LG Monitors connected to MacBook, along with 2 external 2T disk drives for storage and backup).

On phone now with Apple Senior Tech Advisor. WIll update this post with results.

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.

Support Specialist says it takes about 3 or 4 business days from Date of submission before Engineering will get back to him. Since diagnostic and crash data from my system was sent to them on April 9th, I expect to hear back from him mid to late next week.

In the meantime, what I’ve done to workaround the issue is to disable “Put Hard Disk To Sleep” in the Energy Savings tab in System Preferences. Also disable use of power nap. I recommend keeping the screen-sleep option on but don’t let the disk turn off. I did that all yesterday and had no auto reboot incidents.

Next, I plan to shut my laptop down over night. In doing that, I selected the “Open Running Windows/Apps Upon Next Login” box and this should put things “almost” back the way I had them before the shutdown.

Both of these steps will mitigate potential data loss from unexpected reboots AND reduce wear-and-tear on mechanical disk drives, if indeed the system does go through an entire reboot sequence after it crashes.

Hi,

Hello ,

Having had an Extensions problem with two applications, I advise you to go through EtreCheckPro this little software will guide you and highlight the applications whose extensions are not up to date and will give you a relevant conclusion of the problem.

As a follow up on my post, I removed Norton on April 4 after my post, then restarted the computer. Since then it hasn't crashed once or restarted at all.

As I mentioned, I'm in Mojave, so this could well be a separate problem for me, but I'd gotten here with the same error message, which makes me suspect a software problem. I'd held off on updating only because of my Fujitsu scanner, which I love and which had super buggy software with the upgrade to the 64 bit version. Please keep us updated with the Catalina upgrade issues.

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

Mark

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

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.

I am running a mac Pro 10 core with 16GB Vram and 128 gb ram. I have had random crashes under 10.15.3 and was hoping 10.15.4 would fix it but it seems to make the problem worse. Before I was having crashes while working, all video would freeze, but the system would run for a minute before restarting. Now under 10.15.4 my machine is crashing when the Screen saver starts. I tried unplugging 2 external monitors and the screen saver came on with no crashes. Am i too suspect that the external monitors are causing an issue? Is it to do with graphics drivers and metal? Before I had the machine running under 10:15:3 for 2 weeks max when I stopped using the Speaker port after reading something about audio drivers, but it then crashes 6 times in 2 hours. It seems to be when the screen saver started. Could it be sleep mode with external screens?

Did you get anywhere with this? My MacBook Pro Early 2015 has been randomly crashing/freezing since I clean installed Catalina. None of the updates has helped. Still occurring and is extremely frustrating

Still waiting on Apple. I received follow-up early last week with questions about how my sleep settings were configured in System Preferences. I answered those, haven’t heard back since. I’ve worked around my crashes by disabling “Put Hard Disk To Sleep” setting. I’ve disabled all sleep settings EXCEPT for the display. Then, I shut laptop down at bedtime and upon doing so, check the “ReOpen Apps & Windows Upon Startup” option.

This workaround has worked well and I’ll continue it until Apple has a fix. I plan to call-in to Apple this week for a status, since they would have had the problem about 2 weeks. Gotta give them some consideration on cycle-time as their services are slowed due to the COVID-19 situation.
