Catalina constantly crashing when Sleep

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.

When I tried to do this it would not let me. It would not let me move them, I started to move them and it said it was required by OS. How exactly would you do this? I have not tried the operating system yet so I thought I would start with this as a troubleshooting method. Thanks!

Updated to 10.15.2

Problem still persists. Computer completely crashes after going to sleep while external monitor is attached.

There's so many having this issue - any official replies from Apple anywhere?

I have a new 16" MBP with very similar "wake from sleep" issues. Screens dead, computer rebooting during sleep, etc. None of the recommended voodoo worked until the 10.15.2 update. I've been through two extended sleep/wake cycles now. While there's still a little bit of system confusion on awakening - some on and off blinking of multiple monitors as well - there's been no rebooting while the machine was asleep, and at least on this admittedly small sample size of two cycles, the problem seems to have gone away.

This kernel panic or need for hard restart occurred several times a day for the past two weeks since I've had the new MBP, and I almost thought it was a problem with the hardware since it was so predictable. I think the jury is still out on whether this update actually fixed the issue, but since nothing else has changed on the system, I think it's a good bet (at least as long as the system remains stable for the next few weeks). Good luck if you're having this problem. I'd recommend the update and see if it helps.

Question for OWC owners: How long does your Thunderbay with hard drives go to sleep after starting sleep in OSX? Mine was about 30 to 60 seconds. Then instantly it reboots (crashed). If you have sleeping blue light on Thunderbay in few seconds, this may be why yours didn't crash? My hard drives are: Seagate Exos 7E8 8TB Internal Hard Drive HDD – 3.5 Inch 6Gb/s 7200 RPM 128MB Cache

Maybe that is it!

10.15.2 update didn't help.

I have an issue with a different product from OWC. I'm using thunderbolt drive docks. After I put the computer to sleep I would say it happens a few minutes later. It happens with any internal hard drive I have connected to them (I have a few types).

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.

Catalina is definitely the catalyst for this sleep - crash cycle... just wish these kind of issues were published so we didn't waste time fault finding. I thought it was OneDrive app but when I installed amphetamine, it stopped!

Thank you @timjtim for that suggestion it worked a treat and saved me a trip do the Mac Doc.

system> iMac 2015 with NEW 1TB SSD installed internally to replace 3TB fusion drive that died.

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…

Tony's suggestion worked for me. Since I moved those .kext files away from the Extensions folder my mac has been waking up from sleep reliably (knock on wood, hoping I am no hexing myself here). I am not touching 10.15.2 for a long while.

Well I've installed 10.15.2 and tested it over the last few days and several sleep cycles. It works! My sleep problem has gone. Previously the native apps would not work after sleep and a reboot was always needed. Apple said that they were going to issue a fix to the problem. They identified the issue only after many hours on the phone and multiple screen shots and sys log submissions. This appears to work!

So anyone with similar issues might want to try 10.15.2 and see if it works - so far it has for me!

My temporary solution is to turn off OWC Thunderbay power and it never crashed during sleep even in several days. If left on, it will always crash during sleeping even with 10.15.2 update.

I sure hope OWC is working with Apple on reproducing this issue. I have 2016 MacBook Pro with Touch Bar and CalDigit's ThunderDock 3 (tried OWC direct without ThunderDock and still have same issue). It seems most issue is for iMac but I have the same issue on my MacBook Pro.

Maybe when OS X sees the MacBook Pro is a SSD only internal drive and has a bug for attached external spinning drives going to sleep?

Absolutely nothing attached, its a MacBook Pro 2013 (Mid) and would crash with nothing at all attached. I connect it to Synology NAS when I need to, so not all the time, but that made no difference., neither adding an SD card to download photos made no difference, it would always crash on every sleep.

Just opened it after closing the lid last night at 20:00 and no crash :-) So I hope Apple fixed my problem with 10.15.2 which I upgraded on Sunday morning.

Happy days again

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 only have this issue when I go to put it on sleep with OWC Thunderbolt Drive docks . The problem happens from any drives I put into the doc. I even tried it with USB, and it didn't crash the computer but it ejected the drives.

I need to use these drives so what I've been doing is just keeping it awake and then putting it to sleep at night.

I am concerned with all the different tests that I'm doing that I could be messing up the computer. I had to done the upgrade and it didn't change anything.

Is anyone else having the same problem only with the OWC Drive Docks?
