Not Booting, Stuck on Apple Logo
Boot-loop or failure to reach login. Can indicate NVMe storage controller fault, corrupted SMC, or power delivery issue.
Extreme Thermal Throttling
CPU performance drops to minimum under any load. Usually thermal paste, fan, or temperature sensor. Occasionally a power rail voltage fault.
Fan Running at Max Speed
Constant loud fan despite cool temperatures. Temperature sensor failure, disconnected sensor cable, or SMC fault.
