3 shorts beeps 3 long beeps 3shorts beeps
Hi, my mac had lion osx and a bootcamp partition with window 7 .working fine. I did the upgrade to yosemite and the try to boot on windows and the mac restart and the screen went black and only the 3 short beeps 3 long beeps 3short beeps is what you get.
The mac wont boot, only the beeps, try to change the HD or reintall osx,but wont happend.
It's like the bios of the motherboard was changed by yosemite or something lik that or the efi rom chp is corrupted...any clues?
Is this a good question?
