Mac Mini crashing on sleep

Interesting idea about Safari. Wasn't Safari updated at the same time as the latest Mojave Security Update?

I have decided this is not a sleep issue as my Mini-8 continues to crash when the computer is left on. Also, I shut down the Mini every night and almost every morning the crash message is there.

More concerning is crashes during the day. I have yet to experience a crash while working. It seems to happen when the computer is left running while I am away. I'll come back a couple hours or more later and the Mini is still running, but with the Bridge OS 4.4 Crash Message present and some docs not closed properly.

At some point while I was gone it crashed and restarted.

Shut down and sleep are not scheduled via Energy Saver.

The only Energy Saver item I use is turning the display off after 90 minutes. I'll try turning off that setting.

Today I finally got a crash report with all of the details, the "bug_type":"210" etc. on my 2018 Mac Mini.

Have any of you checked your Activity Monitor for a recurring ReportCrash process? On my system it can use up to 98% of my CPU, and reappears at the top of the CPU list every 5 seconds or so. I was on the phone with an Apple Tech for about 30 minutes yesterday, and unfortunately my actual crashes never produced an on-screen report, so we may have been chasing the wrong symptom. He left me to do the whole SMC etc. process, and by what I've seen of the work everyone here has done, that that will not be useful.

I await a fix from Apple.

I am running the latest Beta version of Security Update 2020-003 for 10.14.6 and unfortunately the problem still persists. They've also disabled the possibility to turn off MacOS update (on the Mac Mini, not on other Macs) so it seems like Apple is giving up on this problem and will force us to update to MacOS Catalina. For me personally this would be unacceptable, as some software I depend on for my livelihood is not compatible with Catalina. There is also no alternative.

We don't know for sure until the final release comes out though so let's keep our fingers crossed.

I have a Mac Mini 8,1 (i7) and Safari has absolutely no effect on stability. It's solid as a rock as long as I don't sleep. If it goes into sleep, it panics, period. Firmware version 17P5290, the same as MagicQ.

I also have a 2015 MPB and it only crashes if Safari is running while it's charging with the lid closed (sleeping).

It's a nutty error. I also have the bridgeos implied in the problem.

Hi mavots, that's interesting. Please let us know the result.

I currently turn off energy savor (except monitors) to solve the issues temporary.

Does anyone know how much I can actually save the energy if I turn on the energy savor?

My Mac Mini is a little warm in the morning without energy savor, but it's not bad as I expected.

Definitively some piece of software that sits on some chip. Haven't read anything about anyone who could fix the issues by a clean install of High Sierra, Mojave or even Catalina. Don't even think that a firmware reset via Configurator would help, as it would most likely just install the newest (broken) version again.

…and there is just sooo much to choose from:

About the security content of macOS Catalina 10.15.4, Security Update 2020-002 Mojave, Security Update 2020-002 High Sierra - Apple Support

No wonder that Apple needs so much time to fix this. But they should, as many users are running High Sierra or Mojave for reasons.

But it's not only Mac mini, also owners of Mac Book Pro and even iMac Pro are affected.

Apple must fix these issues, but as it takes so much time, it seems it's trickier then one would think.

(Or, worse, it has low priority due to upcoming WWDC, new hardware, new macOS and iOS…).

Personally, I've given up on the idea that these issues are user fixable. As it is obviously Firmware related, it's Apple's turn.

And even I can go around triggering the issues that I encounter, these workarounds do have some disadvantages that I would like to get rid of. At least it's one of the more disappointing Apple experiences from the last 20+ years of usage…

I had written: “The latest update fixed this for me, at least on a Mini 8”

I should have known better.

It worked twice. Problem's returned. I cleared caches and such with Onyx and still coming back. I think resetting SMC works for a single sleep.

There is a program called Macs Fan Control which allows you to manually adjust the internal fan speed. I put the fan to max and heard the internal mini fan ramp up. I selected 'sleep' to see how long the increased fan would last and it was about 20 seconds before the fan was inaudible (presumably sleep impacts the fans too). Once I woke the mini up, the fans ramped back up again to max. So, if it is overheating during sleep, adjusting the internal fan wouldn't seem to solve the issue as the 'fan' sleeps too.

Separately, I did receive an error upon cold reboot even with the external fan on the mini.

When my Mac Mini sleeps, eventually the TV turns off. If I forget to turn the TV on before pressing the keyboard, the screen won’t be recognized. The Mac is still running, since it chirps on key press, it just thinks the screen is off. Yes, it’s a bug, no it’s not my Mac, Apple quality control for software patches is awful.

I have Catalina on a separate volume on my internal SSD, to just try it out. My main OS is Mojave 10.14.6.

I just updated Catalina just to get the firmware update(s), and see the firmware of the T2 was updated.

Now seeing if Mojave is free of these sleep related crashes. I.e. you don't need to downgrade if you installed Catalina on a separate volume.

It’s not my solution but Ian Glazer’s. The only thing I do differently is that I do not really “upgrade” my machine to Catalina, I just use the Catalina 10.15.6 update as a vehicle for the firmware updates. (Still no crashes)

People, T2 is not a reason of our crashes. It is just a symptom. After that evil security update 2020-002 crashes on sleep, wake or boot appeared not only on Macs with T2, but on older models too. Some of them are saying crashes are caused by Bluetooth or memory or GPU or HDMI. Your Macs are saying it is caused by T2. You see T2 error message and it makes you try to address crashes via T2 related options, but I believe it is useless cause real reason seems to be different, more common for all Macs.

With my setup and in light use there are not the same sleep/shutdown-cold-boot crashes in Catalina.

But if I use Safari (triggers this crash for me 100%) in Mojave, shutdown, and then reboot to Catalina there is a crash report but it is different from the same report in Mojave.

I have the very same problem. It started 1-2 days ago, after an (unwanted, but apparently needed) update. Every time my Mac Mini 2018 goes to sleep and some short time passes, it has to be turned on with the button. If only the wake-up is only after e.g. 10 seconds, the desktop will be shown and no authentication needed – this is normal behavior. Hope it will be fixed soon.
