Catalina constantly crashing when Sleep

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?

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).

I applied the latest Catalina update last night. This morning my 2019 iMac is again recovering from yet another crash. I have no clue what the crash log means, but I do see "BSD process name corresponding to current

thread: com.symantec.mes" at some point. Does this mean that Norton might be the cause behind this? The logs are as follows:

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

I have been having this Catalina-crashing-while-sleeping problem consistently on a new 2019 MacBook Pro 16 inch I ordered day-one or two of the new model release. Problem is unchanged by latest upgrade made a few days ago (circa Dec15 or so, 2019) to Catalina Version 10.15.2 (19C57).

It seems as if a good ½ hour of sleep or more is required to trigger the problem. In my case I performed a migration pretty within a few day after receipt. I do not recall noticing the problem during the brief period prior to migration. One or two calls to Apple led me to believe I might need to spend a lot of time troubleshooting, reinstalling OS and stuff, so I am ignoring for the moment, other than routinely submitting those typical automated reports to Apple. If I learn anything helpful I will come back here with a report. ~k

Update on my own continuing Catalina crashing while sleeping problem (2019 MBP 16”): Step one and step two recommendations from Apple Support have each failed during overnight tests. First step was Mac OS reinstallation. That seemed to do the trick for 1~3 hour sleep periods, but there was a crash overnight. Step two was to create a new user and put that user to sleep overnight. This failed also, with the now familiar “your system restarted because of a problem” alert (or words to that effect.).

I am curious about the “run Terminal” temporary solution Bryce mentions above. I will mention that to Apple next time I chat with them as I struggle onward. Perhaps running that utility is preventing entry into whatever Mac sleep state would be analogous to deeper “REM” sleep. I’ll report back any progress.

What I have tried so far with still issues around crashing after sleep.

Tried everything here with no luck, including running the terminal window.

Thought I had it cracked by re-installing Catalina from scratch after erasing the disk. Seemed to work for 5 days without crashing, then this morning crashed again.

One benefit from doing the re-install was that the cleaned up disk looks a lot better, and it was something I had planned for a long time. Quite a few left over files from the upgrade have now disappeared which may be part of the reason for a delay in getting a new crash.

After the update, I immediately linked the macbook to my Synology and that seemed to work fine. Then after five days, I forgot to put the macbook on charge and the lack of charge in then battery while it was asleep shutdown the macbook. I recharge the macbook and when I started it, it crashed.

I will report back if it crashes again after the next sleep.

I also have the same/similar issues as described in this thread.

After upgrading to Catalina my Mid 2015 MBP started to crash after waking up from sleep:

Neither Safari nor Chrome seem to be able to load new sites, as if there's no internet connection, while sites that were already open before going to sleep still work normally (e.g. Youtube still playing videos in the current tab, but opening a video in a new tab will result in endless loading). Mail does launch, and I can browse the list of emails, but cannot open any of them. Other apps (e.g. Word, Excel) still work normally (opening, editing, saving files).

When trying to reboot, I have to force-quit any frozen apps. Then Finder also freezes and has to be restarted forcefully. Then the reboot begins as you'd expect, with all the icons disappearing from the Desktop, but then I get an endless loading circle. No matter how long I wait, the MBP won't reboot on its own, I have to kill it holding the power button.

After the reboot, everything works fine, until the system goes into sleep mode again.

My local Apple retailer did a complete system check, hardware seems totally fine. EtreCheck also says that everything's okay.

Which it obviously isn't.

I tried every file-related suggestion mentioned here, but nothing worked.

Amphetamine had no effect on the issue either.

Tried with a new user account. Worked for a day or two, before the issue returned without me having changed any settings or installed any new software.

Did a clean install of Catalina, which at first seemed to solve the issue. No crashes for three or four days, but yesterday the issue came up again, and is now happening constantly, every time my MBP goes to sleep.

I would be really grateful for any further suggestions.

Also Apple, please fix this, it is really annoying and proves to be quite an obstacle for my work.

I'm currently considering downgrading to High Sierra (where I had no problems of that sort) or even installing Windows 10 via Bootcamp to finally be able to work properly again.

Update 3 and it crashed again (2019 MBP 16”): So... one overnight without a crash and one lunch break with a crash. Only difference was power was plugged in during lunch. Ugh! Back to the drawing board.

Hi , I have the same problem.

I change recently the ssd, for an owc ssd 1tb . And my mac crashes when it going to sleep.

I need to know if it can broken my new ssd.

Or someone try to back to the previous OSX ?

Having followed this thread for months now and with my iMac 2019 crashing at least once a week still (its not connected to anything, as is the case with some other people reporting the same issue), I am truly amazed about the lack of response by Apple. For a machine that costs more than 2k this is truly unacceptable and this is the first time I'm seriously thinking of selling it.

I am pasting the latest report here in case anyone is listening.

Yes, I find this truly remarkable that apple isn't engaged in this situation at all. It really makes me think twice about purchasing another apple product. Catalina sucks and their lack of engagement in fixing it is worse. I HATE PC products, but I'm getting close to needing to replace my laptop and truly considering other products out there. You can get more bells and whistles for your money.

I am having roughly the same issue here.

MacBook Pro (15-inch, 2018)

macOS Catalina 10.15.2

Radeon Pro 560X 4 GB

Intel UHD Graphics 630 1536 MB

I am connecting my mac to an external monitor via a usb-c adapter and HDMI (various combinations seem to change the behavior):

1. Vava USB-C hub: https://www.amazon.com/gp/product/B079GSMZ7G/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
2. Stouchi: https://www.amazon.com/gp/product/B075S4LQ76/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I am doing PD directly from the apple power cord.

I am looking at getting a hub like the caltech TS3 Plus as that will do PD. But I'm worried that wont solve the issue here. I have two different behaviors.

1. If I keep my laptop connected to once hub and power, eventually the machine will sleep and crash. I have sent numerous reports to apple on this
2. Once in a while, if I am working else where and then try to come back to my desk and plug in the hub and power, I get a kernel panic and an instant reboot a few seconds after I plug in the hub.

Looking at the CalTech, it seems like this is related to hardware as they recently pushed a firmware update that is supposed to solve the sleep issue.

Any advice here?
