My MacBook Air loops in chime sound and wont boot up
Hi My Macbook air 2015 keeps on loop chime on boot up…
1 Should i try to boot from a usb just to isolate the flash ssd.?
Hello. First you’ll need to find what exactly is wrong. It could be many things (Motherboard, SSD, NVRAM etc) First try resetting the NVRAM:
If this doesn’t work, try booting from the recovery:
If the recovery doesn’t even boot then there is something else wrong perhaps the motherboard.
