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

Hello everyone,

since installing the Mojave Security Update 2020-002 I do get a message that my Mac Mini 2018 was restarted because of a problem even I shut it down normally. The Mac Mini 2018 was running fine for 3 months. The Apple Hardware Check does not show any errors. Also tried to reset SMC and PRAM.


Is this a known bug? Just curios wether Mac mini 2018 users who also installed Apple's Security Update 2020-002 do see the same error message?


The Diagnostic Report reads as follows:

{"caused_by":"bridgeos","macos_system_state":"shutdown","bug_type":"210","os_version":"Bridge OS 4.4 (17P4263)","timestamp":"2020-03-28 22:10:39.00 +0000","incident_id":"907CAD79-9364-4588-A25A-3810D0E72F8F"}

Answer:
Answer:

I am pleased to confirm that BridgeOS firmware version 18.16.12561 fixes the Kernel panic bug_type 210 on a Mac mini 2018.


Solution:

Installing Big Sur on a separate volumes updates the BridgeOS firmware version 18.16.12561. When you reboot back into Mojave you do no longer experience the error message on cold reboot. After 7 months Apple finally fixed the issue. Apple never replied on any of my Bug Reports.


Note: Installing Security Update 2020-006 on macOS Mojave 10.4.6 does not fix the Kernel panic bug_type 210. You have to install Big Sur on external drive prior going back to your Mojave installation.

Workaround: Do not use Safari until Apple fixes the bug. Also make sure to set the default browser to Firefox, Chrome, Brave... which prevents opening Safari by accident. The shutdown message no longer shows upon a cold boot.

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).

QuickPost, unfortunately a clean install does NOT solve the issue. As soon as I install Security Update 2020-002 the the annoying crash report still shows up.


Just to be clear. The error message shows up everytime I press the Mac mini power button on cold boot. The kernel message does NOT show up after reboot.

So a clean install works without those cold-boot (or sleep?) crashes _until_ the Security Update 2020-002 is applied, right?

I sent the following message to https://www.apple.com/feedback/macos.html


"Previously a very stable Mac mini 2018 has now started to crash after going to sleep. Also after a cold boot there is a crash report. This started to happen after Security Update 2020-002 (Mojave). Resetting SMC or PRAM or safe-boot or checking with Disk First Aid does not help."


...I noticed that my recent tests with Catalina 10.15.3 -> 10.15.4 also updated the firmware (from Boot ROM Version: 1037.80.53.0.0 (iBridge: 17.16.13050.0.0,0) -> to Boot ROM Version: 1037.100.359.0.0 (iBridge: 17.16.14263.0.0,0)). Do you still have some older firmware? If yes, then the culprit seems to be the Security Update 2020-002.


Does this happen on other Macs?

I would try resetting SMC again. A trick I saw later, to make sure it actually reset, is to disconnect all Internet access, and then see if the time is wrong when you reboot. If the time is wrong, you reset the SMC. (I can't vouch for that being true.)


what does it say when you go to terminal and type


sudo log show --predicate 'eventMessage contains "Previous shutdown cause"' --last 24h


?


Things I tried that did NOT work:

1) Reinstall Mojave

2) Safe Boot

3) Reset PRAM

4) Around two dozen other tricks

I found the respite to be very temporary. Since then I have reinstalled mojave, created a separate clean install, safe-booted, and updated my external clean install of Mojave to Catalina, and talked a lot to Apple. It won't sleep in Catalina. The supposed solution is install on the boot drive. Not happening...

Hello,


having the same problem, on a iMac pro-mojave, since the security-update. the only solution, which lasted for just one day, it was resetting the SMC. But after shutting down...it came back at the reboot. This is the D-report:


build" : "Bridge OS 4.4 (17P4263)",


  "product" : "iBridge2,1",


  "kernel" : "Darwin Kernel Version 19.4.0: Mon Mar  2 20:38:56 PST 2020; root:xnu-6153.101.6~2\/RELEASE_ARM64_T8010",


  "incident" : "37088D82-F5C5-42CD-91BB-C2F20BC3CD3A",


  "crashReporterKey" : "c0dec0dec0dec0dec0dec0dec0dec0dec0de0001",


Would you say is it a real crash(so we should be worried about hardware) or just a bug that gives this message (so we all should not be worried until next update)...?

When I put the Mac mini 2018 to sleep (either while logged in or after logging out), its light on the front goes OFF and it reboots. So that looks like a real crash, right?


If I then do not log in, but put the Mac to sleep at its log-in screen, there is no crash. It seems to crash when going to sleep only after a logged-in session. AFAIR this happens on other accounts as well.


After a cold-boot there is a crash report although _then_ there doesn't seem to be a crash involved.


And only a few random times I have been able to provoke a sleep-related crash when booted from an identical cloned _external_ USB disk. The internal disk always crashes after a logged-in session when putting the Mac to sleep.


I hope there is a system update that fixes this soon because repeated crashes might corrupt the system.

Also see https://discussions.apple.com/thread/251226783?


And yes, it's a crash on sleep, very common apparently on Mini 8,1


Add it to the “monitor won't wake” bug and the “disconnect Thunderbolt when Bluetooth goes on” bugs
