New 16” MBP Random Restarts and LockUps

On my new 16 inch MacBook Pro, when the machine is idle, I get about four random reboots a day. And, when the machine is in use, at least one lock up per day that requires a reboot.


I did not use migration assistant when the machine was set up, it is a fresh install. Hardware check shows no errors… Extremely frustrating.


This is always the message upon each random restart


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


Needless to say… This is very frustrating! Anyone else had this issue?

Just an update on my progress. My prior MacBook would unexpectedly freeze for 10 seconds, then the fans would go 100% for 5 seconds, and the machine would then power off or restart. I would check the logs after this issue and get a "bad magic" kernel panic. They sent me a brand new replacement. This issue seems to be resolved with a brand new replacement. This is a hardware issue (unless you're having panics due to the most recent version of Catalina). If you're having kernel panics, bad magic issues, or unexpected shut downs/reboots, then I'd recommend to get a replacement as soon as possible. This is the only way to resolve this issue.


I spent countless hours troubleshooting the issue with Apple and sending it out for repair twice. The first repair, they only reinstalled MacOS and updated my T2 firmware. This didn't resolve it. The second repair, they replaced my Touch ID Board and Logic Board. This also didn't resolve the issue. I then requested a new replacement (since I'm still within my warranty). They approved this and were able to send me this brand new replacement. This replacement does NOT have any issues and now the issue is resolved.


Please keep in mind that Apple (US) will only send a replacement after a certain number of repair attempts (usually 2-3 attempts), if you're past the 14-day return date. So please make sure to get started on the repair process and after the second/third repair, ask for a replacement. This is the only way to resolve the issue. It was the only way for me to resolve the unexpected shutdowns and reboots with "Bad Magic" kernel panics. I have read prior that this is the only way others have fully resolved this issue. I hope you all have the same success as me!

Same issue here. Ordered a 16inch MacBook Pro 64GB ram which had to be shipped from China and right in the first week of using it started restarting multiple times specially every time is went to sleep and I come back finding it to be rebooting upon when tried to wake it up. Frustrating probelm, I have returned mine for a refund now and hoping for a fix so I can re-purchase!

Were it just a matter of "the drivers," everyone's machine would experience this issue, and many do not.


Mine happily goes to sleep all the time and I haven't had an unexpected reboot since early March., when I shut off Power Nap.


I reenabled Power Nap three weeks ago, and I still haven't had any issues.


There is an interaction I am sure Apple is trying to sort out, especially given I am sure a substantial proportion of their own engineers have an MBP 16.

Just got off the phone with apple support who are STILL DENYING this is even an issue. I've spent $3300 on a new machine that is less reliable than the 5 year old macbook pro I was using before. And apple support just wants you to update, then re-install, -then schedule 4 hours out of your day to visit their idiot bar, then exchange for a new one? Give me a break!
