I've spoken with Apple Engineering many times over the last 9 months on behalf of myself and my clients. I'm guessing you haven't.
People are trying to solve a specific problem and I know how to do it, having been successful 100% so far. What's your point? (that's rhetorical. I'm not interested in your answer).
I just discovered to my surprise that the 2020-007 update did apparently downgrade the T2 firmware from 18P50402b (one of the latest Big Sur Betas) to 18P3030. Bridge OS Version is 5.0. Which is not without problems, unfortunately, as I get intermediate crashes every couple of days. I don't think I've experienced such crashes before. They happen while working: suddenly everything freezes and after approx. one minute the Mac Mini reboots. 19 crashes this December alone! Hats of to Apple, once again,

That sucks. It solves crashing issue on Mojave (thank god), but breaks Big Sur.

Oh really. Haven't run into this issue yet.Unfortunately I'm on Mojave, and T2 *is* crashing on me. But the bug is new and not related to the sleep bug.
While not directly related to the kernel panic issue, but this is actually an upgrade. Beta builds of Big Sewer T2 firmwares are numbered as 18P5xxxx with a letter followed, that means if the build 18P50402b is to be released to public, it would be renamed as 18P402.I just discovered to my surprise that the 2020-007 update did apparently downgrade the T2 firmware from 18P50402b (one of the latest Big Sur Betas) to 18P3030. Bridge OS Version is 5.0.
This is an old error and it was caused by the developer of one of your apps.Unfortunately I'm on Mojave, and T2 *is* crashing on me. But the bug is new and not related to the sleep bug.
Until you've run this by Apple through an actual support case, it will not get solved. Apple Support for MacOS issues lasts three years—they and the EU have agreements on this—and it's free.Same. I get those crashes every couple days now. Seems like Apple simply can't fix the T2 Mac mini's. I kinda gave up on warranty by now. Even though Dutch law states I have the right the have a working product for as long as a product should last. (around 7 years in the case of a desktop computer) Now Apple is using the covid-lockdown as an excuse they can't help me. When the lockdown is over they'll use another lame excuse. Tired of this ****. The Mac mini 2018 / 2020 is the worst Mac I've owned. Waste of money.
I have finally got time to do some final clones and backups and will jump to unknown (= new fw via some "security update").Hello everyone. Just installed a new update and the firmware T2 go from 16P3030 to 18P4346
All good, no errors by now
I did the update and had no problems.I noticed a new security update from Apple macOS Mojave Security Update 2021-001 10.14.6
Anyone install this and running without issues? Panic bugs?
I was feeling lucky and did let the automatic updates run.Mine is 18P52551s.
This is like REALLY good to know.Until you've run this by Apple through an actual support case, it will not get solved. Apple Support for MacOS issues lasts three years—they and the EU have agreements on this—and it's free.
Huh? Many 32 bit apps stopped working in Mojave. Apple cannot fix that; only the developers can. That is not an MacOS issue for Apple support.This is like REALLY good to know.
So far, every problem I had with mini2018 back in 2019, was finally resolved by local phone support stating that "Apple only supports last version of the OS. If you don't upgrade to that, we can't help you." And for me with Mojave, bacause 32-bit, was a goodbye.
The problems were not the 32-bit apps. I mentioned 32-bit as a reason to stay in Mojave.Huh? Many 32 bit apps stopped working in Mojave. Apple cannot fix that; only the developers can. That is not an MacOS issue for Apple support.
Finding old, incompatible .kext files causing kernel panics, OTOH, is something that Apple will do for you proving that you initiate the call and let them install a tracer that lets them capture the event. Sometimes, they have to send it to Engineering as with me last year but the lower tier techs are getting better at identifying the problem files.
Many of the people I work with are in the music industry or are long time hobbyists. I keep a list of known offending files. Often, just removing those is all it takes. I’ve posted it in one thread but can look it up again.
Well, 2 months later I decided to revive mini again using Apple Configurator. It updated BridgeOS to 18P4346, then mini booted to Mojave and I could install Security Update 2021-01. After rebooting got one BridgeOS crash at boot time. Rebooted it again and it still works with no crashes.Wll, I understand your point, but this Mac mini is not eligible for the service. At first I'd try to fix it by myself.
2018 mini with i5 3.0, 256 gb ssd, 8 gb ram
It's a long story. It worked as a build machine in our company for 2 months and then just died, we couldn't switch it on anymore. We brought at service (I don't know where it was) and in a month according to the documents the motherboard was replaced and everything was wiped. We already bought a new mini then, so this one was a reserved machine, but not used for half a year.
Later I got it and wanted to use as a build machine too. It worked for a day or more, but then I decided to install Catalina from App Store over Mojave to it, but once the upgrade was downloaded and mini rebooted to install, it failed to boot. And it couldn't boot anymore (infinite boot loop again), so I ran Hardware Diagnostics and restored Mojave. But it didn't work well even for an hour because of random crashes and eventually fall back to boot loop. I left it for a while.
Recently I read the new about Bridge OS update, revived mini, but all the problems remain. I noticed, that it works well when it's cool and no displays connected (I use it via Screen Sharing).
Fan is running according to iStat menus.
10.14.6 (18G6042) installed, this is the latest release with all security update onboard.
This Security Updates is already installed, but... you know.A really strange issue you've got there with your Mac Mini. As of today there's yet another Mojave Security update, which I have not installed yet. Maybe give it another try with the newest update.
Since it's not a bug, expecting a fix without finding the problem is an unrealistic expectation.Sooo... No, they did not fixed that bug. It works better and even can boot normally, but you cannot use it. If you do anything complicated, it just restarts with 210 error again and again.
I cannot even install Catalina over Mojave because of sudden restarts. mini goes back to the shelf as a decorative thing.
