2 fan spin once, stop 1 sec and the process repeat himself
hi guys. so, my machine is a MacBook Air (A1456) 13' 2015 (i7 8GB 128GB).
just downloaded the update (Catalina 10.15.5) and restarted. after the installation window appears he went down. the only thing it did was the fan spin once, stop by 1 sec and then always repeat. I opened and remove SSD and nothing so I reconnected the battery plug on the motherboard. done.
where do you think the problem will be? on the battery? cycle count - 539 I also had another problem before. the mac would turn on, the bar would fill 2/3 and then freeze until the battery ran out. after a month off, I opened it again and reconnected everything, it worked.
Это хороший вопрос?

Are you able to run the onboard diagnostics? Restart the system and press the D key. Let us know what errors you get.
