Catalina constantly crashing when Sleep

Hi everybody,

I might have solved my sleep crash issue. Three days without problems so far, so I'm cautiously optimistic.

If you also experience mostly browser related crashes, even after a clean install (see my previous post), you might want to try the following:

1) Test if the issue also happens in safe mode (restart holding the shift key, open some programs, let your Mac go to sleep, wait for a bit, wake it up). If you cannot reproduce the crash in safe mode, you might be lucky and the next two steps will do the trick for you.

2) Now restart in regular mode and reset your network settings (https://macreports.com/how-to-reset-network-settings-on-mac/). I used "Method 2" from the linked article. Don't forget the backup.

3) Uninstall or deactivate your network security/virus scanner app(s), one by one if you have several running, and see if the issue still occurs. In my case the culprit was AVG Antivirus. Never thought of it because it never caused any problems prior to Catalina. As soon as the app was gone, no more crashes.

I hope this works for you, too.

After uninstalling Kaspersky Security my MacBook Pro 13" 2017 stopped crashing when waking up. If you google "KIS 20 freezes MacBook Pro (Catalina) after waking up" you should find a thread on this. AFAIK, Kaspersky is still "working on this".

The crashes started after upgrading to Catalina from Mojave and remained with the updates up to 10.5.3 (current as of 3/18/2020). Perhaps there is more than one cause.

Well just for your information. At the end, my service center ended up to replace the whole board (including CPU, Memory and SSD). And problem gone (of course). But from what they tested before replacing the whole board, the crash during wake was caused by a corrosion on the logic board. When they clean the corrosion, no more crash after wake.

Why they replaced the whole board was due to left side thunderbolts port doesn't work at all and difficult to replace only that part. That's why they decided to replace the whole board..

Well, for you who suffer from "CRASH ON WAKE", what I can suggest really:

Bring to Apple Service center to inspect (lucky if you still have warranty or extended warranty). And could be something similar to my case which is related to board issue.

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

Update 2 and a preliminary sign of success (2019 MBP 16”): I removed Avid's "Avid Application Manager" app and its associated Library/Application Support/Avid/Application Manager subfolder. Next day, today, Jan6, there was no crash! System just woke up as it should. I hope this news is helpful for others on or visiting this thread. I did notice, searching about this app, that there are a few "issues" with it so perhaps this was indeed my culprit. I'll report back in a few days. Good luck to others!

Hi, finally yesterday i solved the problem with the most easy way.

I back for the previous OS, Mojave.

So i needed to know that it works perfectly, so i led the macbook pro staying all night on in sleep mode. So, few minutes ago i tested if it'll crashes again. And it works perfect.

So in my experience to save time and worries, return to the previous OS till Apple fix all errors in Catalina OS.

There are a combination of things going on from hub to display. But much of what's happening seems related to Catalina's handling of non-Apple external devices.

Here, I think my issues included an OWC Thunderbay enclosure and how the MBP dealt with sleep on external drives. Setting the computer and drives to never sleep helped there, but it was really just a kludge. However, it did help focus the troubleshooting on the drive sleep problem. I'm pretty sure now that the enclosure was a piece of the problem - I can at least rationalize the external monitor problem as being related to the enclosure too, since the monitor was connected through the enclosure.

OWC had recently posted a firmware upgrade, so I upgraded the firmware on the OWC external device. Probably helped - at least with any issues that were caused as a result of drives or monitor going to sleep.

However, the crash problem really vanished the week before when I downloaded the 10.15.2 Combo Updater (not from Software Update or App Store) directly from Apple. An earlier removal of kext files related to drive enclosures likely wasn't a factor because the Combo Updater replaced those files. But that fix (for some) did point out that something related to external enclosures may have been a piece of this problem.

Originally reinstalling Catalina and then adding supplementary updates on top of that didn't really fix anything; I'm kind of thinking now that the Combo Update may have included some files (or removed some files) that the direct installation of Catalina and supplemental upgrades didn't. Because I applied the Combo Update and the system worked as expected for a week before I upgraded the external device firmware, I can at least say that upgrading the firmware did not affect system software fix.

I remain pretty well convinced that it was the application of the Catalina 10.15.2 Combo Update that "Fixed" my problem - however others say that it hasn't fixed theirs. https://support.apple.com/downloads

Update 4: Okay, I am pleased to report that I have gone over a week now with no more crashing while sleeping on my 2019 MacBook Pro 16 inch running macOS Catalina v10.15.2 (19C57). I elected to start from scratch 9 days ago, by doing a complete disk erase and fresh Catalina installation. This go-round I elected NOT to do a Migration from my old 2013 MacBook Pro running High Sierra, relying on the cloud instead. So far, knock wood, this approach seems to have defeated whatever was my culprit.

In my case my system would almost always crash after sleeping overnight or after an hour or so or more in sleep mode.

Hope this is helpful to anyone visiting here. Good luck!

Update 6: I reached out to Apple and Focusrite on the topic of my newly-installed Focusrite Control app I associate with renewed crashing while sleeping. There seems to be some "kernal panic" history here so I have been advised to review this following article, which also links to a step-by-step YouTube instructional video.

How do I Delete my Audio Preferences on Mac OS X?

https://support.focusrite.com/hc/en-gb/articles/206849239-How-do-I-Delete-my-Audio-Preferences-on-Mac-OS-X-

*Please note that if you do not feel comfortable with the outlined steps or encounter any errors during the process, please do not proceed. At this stage, we would suggest contacting an Apple specialist for further assistance.

If you are experiencing issues with Audio on Mac OS X, it's a good idea to Trash your Audio Preferences, as it's possible that they may have become corrupt. You need to ensure you empty your trash and restart your Mac after deleting these files.

The issues that can be addressed by this fix are as follows: kernel panics (crashes), glitchy audio, interface not showing in Audio MIDI Setup/Sound.

Make sure to Restart your computer after you empty the Trash. When you do, the Preferences will regenerate themselves with their Default Values.

I'll update again if I learn anything helpful. ~k

I made some additional test and I found out that only happened wen conectes vías usbc with in my case a LG 5K ultra Slim M. Yesterday’s I left the machine disconnected from monitor I made several sleeps an everything works well both browsers and email working ok, very weird case

Update on my end. I really believe this may be related to cheap docks/hubs people are using. When I first posted I noted that the kernel panics and sleep issue I was having would only occur if I was using the USB-3 hub/adaptor I purchased from amazon called VAVA. The apple thunderbolt to hdmi adaptor did not cause any sort of issue.

So I picked up a hp thunderbolt dock g2 and two USB-3 monitors. Since I started docking the system this way, I have not had the issue since. And I'm down to only one cable for power and peripherals. The only issue I have is with the dock. HP doesn't publish mac drivers for the onboard audio output and ethernet. Thats not a mac issue though, and is a known deficiency with the product. May be swapping this out for a different dock.

Not that this is a solution. It definitely wasn't cheap.

Start a case with Apple Support and keep after it. Let them collect data (eventually) and they may discover a defect on the logic board. This was my circumstance. Physical repair or replacement may be necessary.

I'm having the same problem when my 16" Macbook goes to sleep.

Configuration

2,3 GHz 8-Core Intel Core i9​

64 GB 2667 MHz DDR4​

AMD Radeon Pro 5500M 4 GB​

Intel UHD Graphics 630 1536 MB​

external LG 34UM94 Monitor​

external Keyboard​

external Mouse​

USBC->HDMI Adaptor for the monitor. USBC->HDMI Adaptor​

After updating to 10.15.5 (19F101) each time I want to wake it up it was crashed with kernel panic.

It seems as if I could solve it: 

I removed the Monitor from the HDMI-Adaptor and plugged it to an USBC to Thunderbolt adaptor from Apple.

Now the LG is connected to Thunderbolt not HDMI, with a nice side effect: I can adjust the volume from the Keyboard now.

Maybe this helps someone.

P.S.

Disabling PowerNap, HDD Sleep did not make any difference on my system.

Anyway: It is a shame that Apple makes no effort to fix this! This high price machines MUST work perfectly!

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.

Remove Paragon, it fix my crashes
