Mac Mini 2018 Kernel panic bug_type 210 after Security Update 2020-002

I took my iMac Pro which is still having the same crash and not even Apple was able to fix this. It is ongoing and to the point where Apple has agreed to replace the unit. There is nothing you can do except to maybe go back to (High Sierra) or forward to Catalina. However on Catalina the issue is not as bad as Mojave because the initial boot is different than that of Mojave. I hope you are able to find a happy medium

Its nuts! Every time i leave my Mac unattended for an hour i come back to a restarted computer due to kernel panic. The only way I can leave it is by closing all Applications (except Chrome), then put to sleep. Generally I can wake it up from sleep without any issues then. But step aside to have lunch with multiple windows open, and boom! restarted.

I never use Safari, but I still get kernel panic restarts. What seems to reduce the recurrence is to shut down every open application (except Chrome which I don't shut normally), disconnect external hard drives and then put it to sleep. Kernel panics still happen occasionally this way but a lot less frequently.

Do you guys check memory usage?

I would recommend to check it with a free App like Memory Diag from App Store.

I noticed significant memory usage with Safari, so upgraded memory from 16GB to 32GB.

Now I see 30GB of usage with Safari once in a while (ridiculous size for Web browsing).

I sill have a sleep issue, but no crash with Safari since memory upgrade.

Not a real solution, just a workaround, but I hope this helps.

Hi!

I have already described that on my mini it helps to reset PMC and then not using Safari.

I also upgraded the firmware from Big Sure. Everything is ok with one exception. The update of SU 2020-005 and Safari on 14.01 still breaks many small things, e.g. the mini does not display correctly icons for links to www. Therefore, after the firmware upgrade, I leave Mojave without SU 2020-005, without macOS Suplemental Update and without upgr. Safari 14.01.

This is what my mini looks like.

Question: are you using a newer keyboard? I just had two successful sleeps after i took out my old MacAlly keyboard and replaced it with a newer (still same brand) model.

My 210 is on the iMac Pro. I was able to avoid it by not using Safari any more, and move default browser to Chrome.

Yesterday I noticed repeated very new crashes with my Mac mini 2018 with all latest Mojave updates:

I put it to sleep, after 1-2 minutes it spontaneously reboots and then displays an alert that the system had crashed. This happened four times in a row.

Previously the Mac mini has been very stable. Earlier that day I had done some tests with Catalina partitions (and finally could update them 10.15.3->10.15.4 but my problems there could be explained by having Catalina on a USB stick because on a SATA disk the update succeeded) and suspected that might have a some role. But maybe the recent Mojave updates explain this? I plan to do my normal troubleshooting today (reset SMC, PRAM, safe-boot, Disk First Aid).

Maybe my Catalina-induced (10.15.4 update) recent firmware update to Boot ROM Version: 1037.100.359.0.0 (iBridge: 17.16.14263.0.0,0) is the culprit after all:

I re-tested on a cleanly installed Mojave 10.14.6 with Safari 12.1.2 (without the recent Security Update 2020-002 Mojave or Safari 13.0.5 & 13.1 updates). Also then just using Safari 12.1.2 and then putting the Mac mini to sleep caused a crash (maybe also some other activity besides using Safari can trigger the crash?).

Having the same issue on Macmini-2018, whenever I put it to sleep or it sleeps itself after being untouched, it restarts in sleep. Don't use Safari at all and Chrome is the default browser...

I have the same problem with my Mac Mini 2018 after Security Update 2020-002 and nothing seems to solve it!

It's now 3 months since Apple are aware of the issue and no solution other than moving to Catalina. It's like if they try to force us to move to their new OS version :-(

Not a solution for me because every day I use some Applications not compatible with Catalina for now.

Apple need to correct their Security Update! it's not suppose to give us problems!!!

noonn, I haven't touched mine at all. It's 100% stock.

by the way, I didn't have a crash in a couple of weeks, then installed the latest security update and safari update last week and boom, within hours it crashed.

SSDD... from another thread where I posted what... it’s gotta be nearly a year ago now... use Chrome, never open Safari, change the browser defaults to Chrome, and it doesn’t panic any more. Of course that was for iMac Pro, but still T2 / SSDD...

how long? Never had another.
