Mac Mini crashing on sleep

Some noted it could be related to Safari. There’s a beta developer preview that I’m now trying out, just to see if it fixes this.

I see you've found a new hobby in these isolating times. 😎 But seriously you've done some really good troubleshooting. I hope you get to the bottom of it and are able to post the fix for others who may be having the same issue.

Thanks, those are indeed my goals.

The current round includes removing old Adobe and Microsoft extensions and updaters.

I'm also trying to see if I have anything in common with other people who have the same problems, e.g. both of us using Dropbox.

Quit Dropbox and Adobe Creative Cloud apps, no other apps were open and still crashing.

Not sure what you mean about booting from your Mini. The only way you could do that would require you to clone the drive and then booting from the clone. It would also depend what system your Mini was running. It would be as much effort as a clean install, if not more.

Ah... OK. Everything is on Mojave. I might already have a clone of the MBPro, for backup purposes.

In the olden times, I would put it into Firewire slave mode and then connect it to the Mini as a boot drive... I can't keep up with Apple's removal of features and addition of other features.

I finally did get a crash report. Can you glean anything from this?

If you mean Target Disk Mode you can only be booted from one system or the other. One is always "Source" and the other is "Target". You can't be booted from Target.

Sorry, reading those tea leaves is way beyond my skills.

Gotcha. Installing Mojave on external drive now. I was thinking the laptop would be in target mode and hooked up to the mini, so it could start from the laptop... I have been known to do that in the past... but probably Apple techs would want me to do it this way anyway, totally clean, so that's how I'm doing it!

That's what I'm probably going to do... the question is, will Apple patch it? I've kinda lost confidence in them. It's nearly impossible to get them to accept that something is a bug, and not my fault. Also, they've been trying to fix the monitors issues with Minis without success...

The clean install of Mojave did not work. Only Catalina, which I can't use. Thanks for the compliment - I'll take that - but I really wish Apple would support 10.14 as well as 10.15 at the engineering level. I'd love to have an interpretation of the crash report. I can't help but think there's an answer there.

It's a bit like taking your car to the dealer, and they'll only read the OBD II codes if you replace all the tires first, because it might be a tire issue.

Thanks. I appreciate your help and encouragement. Certainly Apple was impressed that I'd already made an external boot drive.

I will update you if it turns out there was a surprise firmware update when I put Catalina in, and that fixed everything... in the meantime, yes, no more sleeping. I'll probably sleep-kernel-panic it a few times a day out of habit for a few weeks....I'm so used to F4 for Sleep...

I've tried with no external drive. I should probably try the monitor on HDMI. Will do but not necessarily today...

The problem with multiple drive booting is I've already had one problem that required resetting PRAM, and I'd go nuts having parallel systems.

Thanks for keeping track... I'd thought about the monitor but hadn't switched it, I guess I'll do that next (and probably finally).
