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

I formatted my Mac and reinstalled macOS, the solution I was hoping to frequent freezing (after about 30 minutes of normal use). To my terrible surprise, my Mac still froze. A hard shutdown and restart and here I am.

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

I'm at a loss. I haven't installed any software and it froze. A quick hardware diagnostics didn't find anything wrong with my hardware. This is a new 2018 MacBook Pro. It was working great until Catalina.

This is terrible. I place myself in the helpful hands of the internet in the hopes of solving this.

MacBook Pro 15”, macOS 10.15

I have the same issue. Happened within the first week of owning my new 16" MBP. I asked an Apple tech at the store about the error (BAD MAGIC! (flag set in iBoot panic header), no macOS panic log available) and he said he'd never heard of it.

Just happened again for the 2nd time. Computer is less than 2 months old. Very disappointing.

Just happened to me again. This time the diagnostic didn’t have Bad Magic but a pretty long list of things that doesn’t tell me anything.

Hmmm, might be, because I didn't find any YouTuber having same issues.

I'm living in California.

Interesting. I’m also in California.

Yeah, from any "one month later" reviews I watched, I don't recall any of those YouTubers living in California.

Did you have installed Magnet app (to resize windows like on Windows) on your MacBook?

Dec 21, 2019 1:08 PM in response to Netcracker

Not quite sure if it’s region related, I live in the UK. Even when I took into the Apple store for a full diagnostic they couldn’t find anything wrong with it.

Dec 21, 2019 1:09 PM in response to igork3452

I don’t believe so.

Are on you MacBook Pro 16-inch?

Dec 21, 2019 1:13 PM in response to igork3452

I’m on a 2019 13 inch

Dec 21, 2019 1:15 PM in response to TheMostAverageJoe

So, it freezes, then spins the fans fast and then just turns off? - What happens to me on 16-inch.

Dec 21, 2019 1:31 PM in response to igork3452

Yeah, happens every time I wake it up from sleep mode

Hi,

im from germany and had this issue 3 times right now. My system language is configured to english.

Dec 21, 2019 1:51 PM in response to Marcwa122

Ok, could you try and change your system language to german ? It‘s a long shot but worth the try.

Dec 21, 2019 1:53 PM in response to Netcracker

Yes i can try, but its very sporadic issue for me. And after the latest 10.15.2 Update it never occurred again.

Dec 21, 2019 2:01 PM in response to Marcwa122

It’s happened 3 times since I updated yesterday.
