Hello -- I have the same problem as I wrote, but yesterday from the Apple Discussions group someone sent this suggestion, which has worked for me to keep my Mac from crashing / restarting / shutting-down 2-6 times per day-- this suggestion prevents the Mac from going to sleep and it seems to be that it is in the sleep mode when it crashes or restarts:I have the same problem, my Mac mini was solid until this update, now it crashes 4 or more times a day
Hello -- I have the same problem as I wrote, but yesterday from the Apple Discussions group someone sent this suggestion, which has worked for me to keep my Mac from crashing / restarting / shutting-down 2-6 times per day-- this suggestion prevents the Mac from going to sleep and it seems to be that it is in the sleep mode when it crashes or restarts:
He wrote: I have not had the issue with my machine randomly restarting but that may be because I do not allow it to go to sleep on it's own. I have heard the restart issue is related to sleep mode. There is a way to turn that off, which I have done. Maybe you can try this setting on the Energy Saver control panel to see if it fixes it for you.
See the attached screenshot. It shows just the very first box being 'ticked' - to prevent the Mac from sleeping when the display goes off. View attachment 904909
Hope this helps and again, this is not a "cure" -- it just lets us use our Macs until Apple comes-out with an update to the Apple Security UpDate 2020-002 which is causing these issues.

Thanks a lot Steve, I'll give it a try. Yesterday I disabled 'put hard disks to sleep' and the mac didn't crash that much. I'll follow the setup you suggested and see how it goes today. Hope Apple can do something about this soon.Hello -- I have the same problem as I wrote, but yesterday from the Apple Discussions group someone sent this suggestion, which has worked for me to keep my Mac from crashing / restarting / shutting-down 2-6 times per day-- this suggestion prevents the Mac from going to sleep and it seems to be that it is in the sleep mode when it crashes or restarts:

I haven’t installed the security update, is there a way to prevent installing it by mistake or on its own!? I have unchecked the following options, how can i delete the update file that my mac automatically downloaded?
Yep, I have the exact same issue. Same error report too. Updating to Catalina solves it completely. Thankfully I still have Mojave installed on my Macbook Pro from 2017. It doesn't have the T2 chip so it's not affected by this.
This update has made me nervous of updating to Catalina - as has the other thread about a user's Mac mini that was bricked by the update!
Finally, I went into the Repair Partition and disabled the T2 security in the utility.
Am I the only one using a 2018 mini for which Command r boot keys do NOT work?Boot holding the Command r keys To get into the Repair Partition.
Nope. Anyone with a clone on their system will not be able to access the Repair Partition. Likewise, any other Mac OS present on the system will prevent you from accessing it with APFS.Am I the only one using a 2018 mini for which Command r boot keys do NOT work?
As you may have guessed, this has nothing to do with the Repair Partition.Note: The other boot key combinations DO work.
None of that can help since it's not the problem. Neither can updating to Catalina since OS 10.15.4 introduced it also.Disconnecting peripherals, resetting SMC, PRAM, safe-boot, Disk First Aid or even a clean install to macOS 10.14.6 and Safari 12.1.2 does not help.
Sure.
Shut down.
Boot holding the Command r keys To get into the Repair Partition.
From the top tool bar, click on Utilities and select Startup Disk Utilities. Enter your Admin password to unlock.
The screen should be self-explainitory.
The first time I tried it, it required me to create a password to protect the Repair Partition before I could exit. I had to log in again later to remove that.
I didn't say it would fix anything other than that, with the security settings disabled, you can boot from an outside drive.hm.. turns out I already had all Security options disabled.. My Mac Mini 2018 still crashes during sleep..
