AHT error : 4SNS / 1 /C0000008: THSP- - 124
My MacBook air started performing slowly, on running AHT i got error "4SNS / 1 /C0000008: THSP- - 124"
Any idea how to fix this.....
As far as I know, it's a temperature sensor error, you'd better take it to Apple Store Genius Bar.
Before that, try resetting SMC as well as NVRAM which could solve the problem.
