M1 MacBook Professional 13″ 16GB continuously reboots with the identical panic error: acc_cifl2c_cmd_ncwr
I’ve spent a while determining who’s inflicting this drawback.
It occurs provided that M1 MacBook Professional connects to wired ethernet solely (through thunderbolt clearly) with disabled Wi-Fi.
So:
- Wi-Fi solely = no points
- Wired ethernet with disabled Wi-Fi = Panic: acc_cifl2c_cmd_ncwr
Tried:
- A number of/totally different thunderbolt hubs = panic
- A number of/totally different thunderbolt cables = panic
- The newest macOS put in from the scratch = panic
- Protected Mode = panic
I attempted to contact AppleCare assist however they wasted my 4 hours with no outcomes.
The problem has been current since day one we acquired the M1 processor…
The one resolution is to make use of Wi-Fi solely which is a disgrace for PRO customers.
