Catalina constantly crashing when Sleep

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.

I learned this in another thread with this same issue. I was crashing every time the display went to sleep. Once I opened Terminal and left it open in the background it stopped my machine from crashing. It has been on now for at least 5 days with no random shut downs or anything. This hopefully with fix this problem with me until the release a fix for it.

I would suggest using the ComboUpdate to anyone reinstalling Catalina. It seems to have stabilized things here - for the moment.

I'm going to let the computer sleep the drives one more time to see if that's still part of the awakening problem.

I had solved the issue for 10.15.1 by following Tony Jefree's advice of Dec 6, 2019 2:42 AM  (move a set of extension files to a quarantine folder).  

Upgraded to 10.15.2 and the problem came back.  (The quarantined extension files came back, of course).  After quarantining the set of extension files again the problem has been gone for almost a week (fingers crossed).  I am using an external hdmi monitor;  if I use Apple's external Thunderbolt monitor, which I prefer, the problem re-occurs. 

Catalina has not been pleasant.  I am seriously considering Ubuntu. (Frying pan, fire?)

I am having same issue

Catalina 10.15.2

MBP2015

I am o XCode 11.13.1

I noticed this happening when I have Google Chrome open, not always but after couple to Chrome tabs open, it starts happening. So, I uninstalled Chrome, reinstalled it, stopped it from starting automatically on log on and switched to Firefox.

I have not noticed it since I did that (2-3 days ago), however, if I go to Google Maps on Firefax, it freezes my machine again.

The only way to unfreeze is to press and hold power button and force restart that way.

UPDATE: Since I last posted, Engineering got back to me and suggested the likely culprit was my OWC RAM or the external drive. I ran three passes of REMBER, and the RAM passed without any errors.

Since I’d already disconnected the drive for several days, I reconnected it to do a backup and then—because why not?—I decided to leave it connected. It’s now been 8 or 9 days, and there have been zero kernel panics and restarts. Note that I’ve changed nothing: no system settings (such as Energy Saver), no deletions of system software components, and I’m still running the same programs as before.

Because I don’t believe in self-healing hardware, I’m wondering if OS 10.15.3 does contain some sort of fix for this issue. Although I previously had two restarts within 24 hours of installing it, there have none since I disconnected and then—a few days later—reconnected the USB-powered external drive.

Update:

After I posted on their CEO's Twitter, Apple support approached me.

They asked me to test the crash from SAFE BOOT mode. We found that there is NO CRASH when sleeping using Safe Boot mode, but the Mac feels warm (looks like no deep sleep).

Then they asked me to do first aid, which doesn't encounter anything wrong..

Same issue on MacBook Pro 2019" ...

I have an external display connected USB-C to DisplayPort 1.2 on a Philips Monitors 4K Ultra HD LCD Monitor 276E8VJSB. Computer will sleep (energy savings begin, computer rests), upon wake OSX crashes.. Mac reboots and I need to setup the session all over again.

I tried two types of USB-C cables with same results thinking the official Apple supported USB-C cable would resolve, but this didn't work:

1) Cable Matters USB C to DisplayPort Cable https://www.amazon.ca/gp/product/B01J6DT070/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

2) Moshi USB-C to DisplayPort Cable

https://www.apple.com/ca/shop/product/HLR62ZM/A/moshi-usb-c-to-displayport-cable

Still crashes... The only way to circumvent the issue is to disable "Prevent computer from sleeping automatically when the display is off" under Energy Saver... but this isn't a good solution. I use external display quite often with my MacBook and don't want to crush the battery and it always be on.

My macbook pro is SSD and I still get the issue, upgraded to the latest update on Sunday and no crash so far.

I had this problem too.

No procedure and no support could provide any help.

There's one remedy, if you happen NOT to have a new machine: Downgrade to Mojave...

Until Apple fix the problem why not just shutdown the machine rather than put it to sleep.

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?

My 2016 MacBook Pro hasn't had sleep-related crashes over two weeks now after I turned power off of external OWC Thunderbay. I also have HDMI via CalDigit's Thunderdock's miniDisplay to HDMI adapter to 40" 4k Samsung TV but it doesn't cause sleep crashes. I didn't need to move extension files.

OWC company has been in loop with me and they are bringing reproducible physical devices to Apple. We should have some fixes soon. Yay!

For other issues of sleep crashing that some of you experienced, I suggest to contact Apple directly and hope they have enough info to have fixes.

No, blew most of my day yesterday. Did the install and then used it for a bit.

Left my Mac for a couple of hours and came back and it had crashed and rebooted. So...

10.15.3 does NOT fix this issue.

Also: Again, the ONLY time it crashes is when the external 4K screens are connected. I can use the Mac without them, and it never crashes. Whatever the issue is for me is related to Video.

Many thanks to Tony for this suggestion. I tried everything in this thread and the crummy Apple support page, and nothing worked. But when I removed these extensions AND set my computer so that my displays never go to sleep, the problem went away.
