Catalina constantly crashing when Sleep

Thanks Roger. Just to clarifying, though -- setting my Mac to not go to sleep by itself didn't solve the problem, nor did any of the utilities work (Amphetamine, caffeinate, etc.). It was only after deleting the extensions AND setting it to not go to sleep that my computer would stay on.

I also reached out to Apple Support today. Their suggestion was to run a virus scan and then reinstall Catalina. Not very helpful.

Hi, I was never getting crash on sleep so my guess is that it is not related to my case.

However, I have Chrome, Firefox, Brave and Safari browsers. I had to remove hardware acceleration in Chrome, Firefox and Brave. So, all 3. I had no issues with Safari so did nothing there.

Since the 10.15.3 update, I no longer have sleep crash with OWC Thunderbay. I used had to turn it off before sleeping the Mac. Now, I leave it on all the time and not a single sleep crash. All good at least for me.

If you have Thunderbay, give the 10.15.3 update a try.

So I saw more than 400 people encountered this issue. I am using Macbook Pro 15" 2017 and already encountered this issue since Mojave two years ago, and keep consistently happening when put MacOS sleep. I saw some MacOS patch/updates tried to fix this issue, but still happening. I was thinking maybe due some other app or driver causing this issue, but actually it wasn't.

I did all reset including SMC, VRAM all didn't work, and still happening. I put my last hope which is format everything from zero, even using MacOS Catalina which I hope fixed this issue. But even using fresh MacOS Catalina, without any additional apps or drivers, without anything plugged in (only power cable), it still CRASH (kernel panic) after some second sleeping....

I did sent reports to Apple every time it crashes with various comments and clues, but until now.. you see, you all still encounter the same issue. Why can't they just pick up some Mac from users who encountered this and try to spot the root cause? Or nobody works at Apple encounter this issue? Or they feel like this is common issue?

Even you guys encounter this in newest Macbook Pro 16"... I don't think this make sense. Even I have old Macbook Pro 2009 with Core Two Due NEVER ENCOUNTER THIS ISSUE AT ALL! (Of course using old OS haha)..

So what can we do? What can Apple do?

I have had the same problem with my brand new iMac 2019 which replaced a trusty and reliable old Mac mini on Mojave.

Tried the SMC reset and safe mode routines multiple times but no joy. And disconnected all peripherals. The Mac would appear to wake from sleep but apps would all be non responsive and a full reboot was always necessary.

I have progressively disabled and reinstalled apps which I think may be causing a problem on wake up - just in case. A full deletion and reinstall of Dashlane (password manager) using the manufacturers version NOT the one on the Mac Store seems however to have reduced the problem. At least I think that is what helped but in desperation I was trying so many things it may have been something else

However what happens now on wake up is that non of Apple's own document software works properly. Preview, pages and Numbers all report that random documents "could not be opened" . This sometimes relates to doc's recently created but also older ones too. The docs however all open fine with other apps!

And mail has taken to losing the connection with my gmail accounts. It continually demands password re-entry in a loop with the password not being recognised and being asked for again - and again - and again!

I'm using Kiwi for Gmail now as a work around

General non Apple apps all seem to work

A full reboot is required after each sleep wake cycle to get the apps to work again. Bizarre!

Clearly a major Catalina problem

I'll try Amphetamine and see if that cures it for now until hopefully Apple issue a new update. Many thanks timtjim for the tip

Totally rubbish customer care from Apple

This is what I found. There are a number of postings on the internet about problems with AFP and SMB (Service Message Block) for attaching network attached storage using Catalina. Try using Google to search for "MacOS afp catalina" and "MacOS smb catalina".

https://discussions.apple.com/thread/280511

https://forums.macrumors.com/threads/catalina-wont-let-me-connect-to-afp-fileserver.2195290/ States that SMB is preferred over AFP since version 10.8. AFP (Apple Filing Protocol) https://en.wikipedia.org/wiki/Apple_Filing_Protocol was originally designed for AppleTalk

Repeating the Google procedure for NFS (Network File System) also indicates some problems with Catalina. CIFS (Common Internet File System) is an open source implementation of SMB and may be more friendly for some systems.

https://appleinsider.com/articles/13/06/11/apple-shifts-from-afp-file-sharing-to-smb2-in-os-x-109-mavericks In 2013, Apple started moving from AFP to SMB2.

I've posted this before but I want to share the update. The only time I have the problem with the crash is when it goes to sleep is when I have my OWC drive doc connected. I find the same outcome when I attached them via thunderbolt the computer crashes when I put it to sleep. This has been replicated on my laptop also running on Catalina. The one thing that is interesting, is that with the drive docs attached via USB it does not crash but what it does is eject the drives in the doc.

At this time one of my drive docks is under warranty so they are going to send me a replacement to test it. It's a newer model, but if it doesn't they want to gather some logs for Apple.

Has Apple weighed in on this at all? I am interested to know why it seems to happen only with my drive docs and why others are having it happen all the time just by putting the computer to sleep. According to OWC they have not received other reports of this happening. When I return my doc to them they want to run some tests.

Obviously something is very strange with this issue.

That sounds really frustrating. In my case I only have a problem when I have my drive doc on. In my case they had confirmed that it was isolated to when I have my drive docs attached. The people from OWC said they are not getting a bunch of customers with the same issue. They suggest I tried the troubleshooting of removing the extension. I'm going to try that before I install the new operating system. But if it turns out there's a conflict they said the only way to find out is if I do a clean install on a separate drive with no applications I use. All the best to you and I hope the new operating system helps you.

Auto update just did its thing (10.15.2) turning 2 perfectly good computers (macbook pro's, 16 inch and 15 inch) into useless paper weights. Crashes appear to be happening each time an application launches after waking from sleep. Chrome, Facetime Audio, Sketch, Figma, Slack and Safari.

The keyboard slows, mouse freezes, than a beach ball, followed by a black screen. Apple you have to do better.

Sad mac.

After a few days on 10.15.2 the results are mixed. There have been more panics during sleep resulting in restarts, but there have also been normal sleep/wake cycles. The timing (as in a few hours or overnight) hasn't shown any patterns yet. This morning, the system reacted normally to wakeup even after 8 hours of sleep.

I wonder if Time Machine backups could be a piece of this issue. I assume that most use it, and with some comments mention OWC Larry's Tunderbolt bays, I suspect that some are using their TimeMachine drive in one of those bays.

Just another thought, since there doesn't yet seem to be a clear path from sleep to kernel panic…

Great. We both don't have crash when neither os us have OWC Thunderbay is powered on (in your case, you don't have it and in my case, mine is powered off).

Any other OWC owners out there? Can you try turning off OWC device to see if it stops crashing in sleeping?

I thought I'd throw in my two cents as I'm still having this issue with Catalina.

My 2017, 13" MBP running 10.15.2 will, seemingly randomly, crash at three different stages of the sleep/wake cycle - a) mid sleep (usually overnight), b) immediately on wakeup or c) immediately after entering login details. All culminate in the flashing question mark folder and, upon forcing a shutdown and reboot, the 'your system restarted because of a problem' message.

I haven't taken any steps aside from sending reports to Apple. I have noticed that these crashes haven't occurred when all apps are fully closed prior to sleep. I work a lot with Adobe on illustrations/graphics and closing those apps every time I want to sleep my computer is not practical. I keep losing work as a result and it's driving me insane.

Having the same issue, among others, after Catalina was install on my mid 2015 MBP. I brought it into my local authorized Apple place for them to look at. The hardware passed all their diagnostics, so they did a complete fresh install of Catalina.

Other issues involve the system becoming unstable after using apps for a awhile, resulting in having to power cycle it.

If it were just the crash-during-sleep I could work around it, but tweaking settings so it never goes to sleep just results in it some other issue surfacing that causes the system to crash or need to be power cycled.

Needless to say Catalina has not impressed me so far.

Well I finally got fed up and erased the disk and gone back to Mojave.

I will wait for another two releases of Catalina before trying it again.

However, erasing the disk and a clean install of Catalina did reduce the crashes significantly but not enough. I still believe that this is something to do with the power management as that is when the crashes happen if the mac book runs too low on power or out of power and then the next time it starts up it crashes.

I have MacBookPro 2015, never had any issue until sometime mid January, 2020. I installed Catalina before that, as soon as it came out and had no issues. But in January, I started noticing that daily, my MBP will freeze for 3-4 minutes, then restart with that screen saying it crashed.

The things that changed is that I got latest Catalina and XCode

Catalina 10.15.2

XCode 11.3.1 (11C504)

So, I suspect one of these is the cause of this issue. My issue does not occur when going to sleep mode, nor do I loose WiFi connectivity or anything like that. After more observation, I notice it happen regularly when using Google Chrome. However, it happened also with Brave browser. I dont recall happening with Firefox.
