Mac OS 10.15.4: Random restarts due to panic(cpu 1 caller

I too think this issue is connected to the graphics. I reinstalled the MacOs operating system on mine yesterday and I’m gonna test it tonight to see if the issue comes back. Like play some games and binge some Netflix....

Have similar experience, macbook 13 pro restart susually when i close it and leave for awhil, or when i connect monitor or charching cable. This is what i get:

Hello VDawg2018,

a couple of questions:

• how many days have you been without a kernel panic?
• how did you stress test your mac?

For the reinstall i believe you followed hhttps://support.apple.com/en-us/HT204904

Thanks

Hey fellow MacBook user,

of course. Let me know if you have any more questions. I would recommend this route as it has reduced my issues.

one thing I’d like to add is that I was editing a simple Word Doc a few days ago and it just had some tables in it. Nothing hard. The next thing I knew, my laptop froze AGAIN. Nothing was working except the power button. After a restart, which caused the same kernel panic message, I was confronted by a later version of the Doc. Turns out, my laptop had not loaded the past 9mins of edits that I had made in the Doc.

At this point, I am so mad that I just stay away from using my laptop. This issue is getting out of hand and I am gonna have to contact Apple Support for the 6th TIME. Grrrrr.

It’s really unfortunate that you came across this issue with 2 separate MacBook Pro’s. I’m just gonna see what the Apple care advisors say, at this point. It’s funny that no Apple advisors give a crap to help out in this discussion. I really shouldn’t blow thousands on a laptop just to avoid using it. We’ll see. I’ll keep y'all updated with the latest info.

I think Apple just did:

TECHNOLOGY ALERTApple Announces Transition to In-House Chips for Macs

Apple is breaking up with Intel. The company will transition to its own computer processors, in a long-anticipated shift that ends a 15-year partnership.

For me, this has given me a week of no random restarts for now as well.

Although this is not THE solution, it gives some peace.

Looks like when the random restarts start, they gradually increase in frequency.

This re-install maybe resets it.

At least, it gives me some peace of mind for this week.

I definitely agree that reinstalling MacOs fixes the issue to a certain point. At this point, I’m just going to hope that MacOs Big Sur will fix all of my issues. I don’t know when it will come out, but I know that it is going to be an important update. I love how it looks and that change will be enough for me to be willing to open my laptop again. I have AVOIDED using my MacBook Pro for weeks and that update will change that. Time to play the waiting game. Lol.

Same here. Happened today. Closed the lid and when I came back an hour later my Mac had restarted.

Ok I was too optimistic I guess...after normal work after a week of vacation the first day and another crash. Thanks Apple I love you...

Having this same issue on my new 16" Macbook Pro. Most of the time I just get a hard crash to a white screen with no error code. I've also had "Bad Magic" and just had "panic(cpu 0 caller 0xfffffff0142153dc): x86 CPU CATERR detected". This happens pretty much every day with no obvious cause. The last crash was waking up the laptop from sleep with nothing running but three tabs in chrome.

Should I take my laptop in?

Happened again today after a wipe and clean install so I can confirm that reinstalling OS is not a fix. I'm on Catalina 10.15.5

Exactly the same here, the problem was here before I upgraded to Catalina… I had a reboot today again. What is your Model, mine is a MacBook pro 15 2019 2.3GHz core i9. I think it's an Hardware issue too.

I spoke too quickly.

Today I had a freeze. That's a new one though.

I thought my mouse ran out of juice and was searching for spare batteries when I noticed that piece of poo restarting after a good minute or two. No crash report anywhere to be seen.

This takes me back to my Windows 95 years and the blue screen of death every couple of days... and this was the reason I move to Mac in the first place!
