Catalina constantly crashing when Sleep

Same here, did not happened before Catalina, and I suspect that after installed Kaspersky Endpoint Security due to company policy, it have influenced slightly.

Im on:

macOS Catalina 10.15.4 (19E287)

MacBook Pro (Retina, 15-inch, Early 2013)

Processor 2,4 GHz Quad-Core Intel Core i7

Memory 16 GB 1600 MHz DDR3

Graphics Intel HD Graphics 4000 1536 MB

This happens to me too on a brand new top of the line Macbook Pro 16". I just started noticing it since I started using an external monitor. It seems to do with having stuff plugged in. Catalina has really been a huge disappointment in terms of stability.

I've sent multiple reports to Apple. How are they not investigating and fixing this? Incredibly disappointed for a $5000 computer.

UPDATE

With recent OS updates, my crashes are less frequent. Originally, it was thought that my bus-powered USB drive on my 2017 iMac was the culprit for my Catalina/sleep-related kernel panics, so I replaced it with another drive. No change.

Then Apple Engineering said they were sure it was memory related, so I had OWC replace their new 16GB of RAM with another pair. So far, I've tested with only the original pair of Apple RAM (total 8GB), only with the OWC 16GB, and with both sets in both positions. And yet the kernel panics continue. As mentioned, the only good news is that they're less frequent. I went 11 days between crashes this time. Still unacceptable and a complete mystery, but an improvement. Unless I have some other undiagnosed hardware issue, I still think Catalina is the culprit.

Has anyone tried the 10.15.6 update? Does it help?

I'm still using my 10.15.3 rolled-back version which had been absolutely fine with no crashes for weeks now. So I'm reluctant to update if things will start crashing again. However, I will need to at some point so I can access Photos again!

Thanks

Ah, that's great news for you guys. I have been reading in other places that some people are still having issues.

I'll think I'll still wait a little longer to see how others are doing. Fingers crossed its fixed it for most people.

For me the problem was a Time Machine drive that the mac couldn’t write on (It was throwing errors on being unable to write on the drive, when then computer was working). I got a new hard drive and since then that issue has stopped. However I am having a lot of other issues with time machine, (one night it stopped someone suddenly and I had to erase everything to start again). The computer also doesn’t recognizes an old time machine, unless I leave it in the USB port for an hour or so (I heard that is a common problem)

didn’t expect this from Apple.

My system is fixed.

I am using 10.15.5 and my MBP16 has become perfectly stable. I've been doing photo work again and no problems with it at all. I've had 3-4 weeks without an issue. If you review my May 22, 2020 post above you will see the steps I used to gain stability before the 10.15.5 update. When it was released, 10.15.5 installed without issue and has been solid since day one.

I had the same issue with my 2017 iMac... There are two situations I hear that causes this. One is with the video card, apparently there is a problem with the software if you use an external monitor (according to a tech rep)and the second culprit is with an energy saving option in the "system preference" menu. I don't use an external monitor, so we tried option number two. My OS isn't on the 'Latest version' and i refuse to update since there are so many problems with MacOS (being an audio engineer, updates can mean loss of plugins, software compatibility, etc...) and i refused to update... so the gentleman recommended I go into SYSTEM PREFERENCES, ENERGY SAVER (with the lightbulb icon), ENABLE POWER NAP should be checked blue. If the Enable power nap is checked blue, uncheck it, and see if it resolves your issues. I had this problem every day for a few months and got tired of waking up to a completely shut down computer. So far, everything is good on my end and I have my fingers crossed it stays this way. I hope this information can help, or at least point you in the right direction

another UPDATE

In case it's useful for anyone finding this thread.

I had updated to 10.15.4 and experienced endless crashing, updated to 10.15.5 and nothing changed.

I then backed everything up and and formatted my Macbook 16" and installed 10.15.3 and have had zero issues.

Note I didn't use time machine to restore or migration manager. I manually copied over my documents and photos etc and reinstalled everything from fresh downloads. Everything is working great.

I just bought a new 2tb SSD to clone my Macbook and figured, with this clone backup, I'll try updating to 10.15.6. I instantly had issues again. One crash, and upon leaving it for a while returned to open it up and have a red screen! Restarted it, similar issues.

I've restored it using the cloned 10.15.3 and no issues again.

I have no idea what it is. It's really disappointing, especially because I can't access my Photos library for the time being because it's from a newer version of Photos.

Standard procedure of course already tried and not helpful.

Happens to me with 2017 IMac. Only happened after the update to Catalina, and not before.

Facing similar issue with Catalina operating system version 10.15.2 on a 2017 macbook pro. Macbook crashes after extended sleep and reboots every time.

In case of my issue, it turns out turning off Google Chrome Hardware Accelaration setting resolved the issue

It's been about 1 month since My 2017 Macbook 15" started to crash/reboot after lid open. Very annoying. Anyway to fix this?

@timjtim, Amphetamine is not useful for laptops (like mine):

16" MBP with 4 drive Thunderbay 3 on 10.15.2

Amphetamine + kext file removal… Will test without Amphetamine app next.
