"BAD MAGIC! (flag set in iBoot panic header)" — Catalina freezing all the time!

Installed 10.15.4, rebooted and 45 seconds after logging in, it crashed again. Panic log now includes some info instead of just a single line.

panic(cpu 1 caller 0xfffffff01e7737b4): x86 CPU CATERR detected

Debugger message: panic

Memory ID: 0x6

OS version: 17P4263

macOS version: 19E266

etc., etc., etc.

Hmm, I'm actually not seeing the BAD MAGIC side so maybe I'm posting in the wrong thread but I have the exact same issues. It is dying during IDLE mostly, overnight type stuff. It seems the same. Here is a screenshot of what I'm seeing, is this the same as you guys?

Not a great time for everybody to have their top-of-the-line laptops start melting down due to hardware issues. There are no Apple Stores open, and even if there were, we're staying at home to flatten the curve of the coronavirus outbreak. We're stuck with broken hardware and no way to fix it.

Thats exactly where I am and have been since January. The only good news I can report is that the crashdump includes slightly more info than the singe line it did for the last 3 software revisions. Makes me think someone at least realizes there is a problem.

My customer with the iMac Pro (in previous posts in this thread) running Mojave that only had the Bad Magic crash on reboot, is now getting it when switching the second monitor and keyboard/mouse over to a Windows machine via KVM switch. It was working fine that way for months and now it's not, as of April 15.

This definitely isn't solved, and it also is not restricted to just Catalina. My Mac Mini 2018 is subject to random reboots at least once a week with no end in sight, and I'm on Mojave (10.14.6).

"macOSPanicString" : "BAD MAGIC! (flag set in iBoot panic header), no macOS panic log available"

That's all I get.

I will wait till this fall and the release of Big Sur. If my mac will reboot again using Big Sur, i will never buy again an macbook. My Mac rebooted 5 times the last 2 weeks, not in idle, while in normal use! (Only standard Apps like Safari or Photos opened)

It rebooted also with kernel errors like the Bad-Magic. I'm using newest available Catalina.

Its a shame that there is no official statement regarding this issue! Im really disappointed by Apple.

I agree Marcwa122!!

Can't believe Apple would sell defective products like this and not even respond to their own forums where plenty of users have expressed concern.

We need answers Apple!! This is unacceptable for a 2000 + dollar machine.

I noticed it started happening after a security update and new monitor. On Mojave too, not just Cat. I've also had my 2016 MBP keyboard replaced for repeating keys that happened immediately after a security update. These "security" updates tend to cause a lot of trouble. Unfortunately, we can't see when the OS blocks anything bad so we can't stop going to the bad places. Being treated like a mushroom is not cool. I can't promote Apple products as "safer" than Windows based anymore as Apple provides no proof its security is working or even turned on.

Neither Apple product teams, nor Apple phone support participate in these communities, so posting redundant screen shots here will solve nothing, as the associated panic data was already sent to Apple. These are fellow user supported communities and we cannot advise when we don't know what is causing these panics.

Well, with that being said, is there any resource that explains the issue we are all experiencing here? How do we get apples attention on the matter? Isn't that what this forum is for?

Any advice on how to escalate or info/details on a solution or why this is happening would be greatly appreciated.

This is the resource that explains the issue. You can bet Apple looks at these posts. They may not respond but something is reading and analyzing posts. Likely they'll keep quiet about the issue until they eliminate the Bridge OS or whatever they end up doing when moving to their processors.

Every customer I have in the A/V industry ends up disabling all of the security protocols because they interfere with performance. Been happening since At Ease locked down MacOS 7. Because these security protocols work so poorly they have created the opposite effect. Creating a culture of unprotected machines with users intentionally disabling security protocols. Not that Apple didn't start the game by hiding full email and web addresses by default, loading remote content in an email-by default and failing to something a simple as inform the end user that the email they received has a different reply-to address that its actual sender's address. Something easy to see in the email header but hidden from average users, why?

Question is, why is Apple making so much fuss about the Bridge OS and T2 chips? It's ruining their rep in the professional community. If you're using Thunderbolt you've pretty much given up on security anyway. It could happen over night, making customers mad and losing them all.

very interesting this is happening on a mac mini, and here I was theorizing it was the touch bar miniOS trying to do something with macOS ..etc.

So this morning I reinstalled MacOS and it’s stopped freezing/crashing. Will update if it starts again.

The screen capture is as below.
