Reboot on a loop - 2019 MacBook Pro 16in
Hi, My MacBook suddenly restarted and it's now stuck on a loop. After entering password progress bars gets just after midway, fan blows and it restarts again.
I've tried:
- Force shut and turn on again.
- Diagnostics on Recovery mode. No issues found.
- Start and restart from Safe mode.
- Reset SMC.
- Reset NVRAM/PRAM.
- Reinstall macOS
Nothing has worked.
Problem Report gives this:
panic(cpu 4 caller 0xffffff7f8ddca983): GPU Panic: mux-regs 5 3 7f 1f 0 0 severity 3 WS-ready 0 switch-state 13 IG FBs 0 EG FBs 0:1f power-state 0 3D idle HDA idle system-state 0 power-level 20:20 power-retry 0:0 connect-change 0 : PowerPlay Failed to Initialize.
From what I can read, it looks like maybe I'm not the only one with this problem.
Any ideas, anything else I can try? Has anyone been able to resolve it?
Thanks, appreciate any help.
