MacBook Pro 2015 kernel panic/restarting/crashing on login
Hi everyone,
I’m having an issue with my MacBook Pro 13” Early 2015 (MacBookPro12,1) running macOS Monterey 12.7.6.
A few days ago, my Mac wouldn’t boot properly, so I took it to a repair shop. They opened the bottom cover and cleaned the inside. After the cleaning, the Mac worked perfectly for about two days.
Then the exact same problem came back.
Current symptoms:
Sometimes it freezes or restarts at the login screen.
Sometimes there are lines on the screen.
Sometimes I enter my password, the progress bar reaches about 30–40%, then the Mac suddenly powers off and restarts.
Sometimes it reaches the desktop, but after a minute or two (for example, while opening Chrome), it suddenly crashes and reboots.
The same thing happens even in Safe Mode.
I erased the SSD and performed a clean installation of macOS Monterey 12.7.6, before all of this happened
I captured a kernel panic, and the backtrace references:
IO80211FamilyLegacy
AirPort.BrcmNIC
Apple Diagnostics had previously reported PPM002.
Any advice on what I should check next would be greatly appreciated.
Thanks!
