Hi. I have a mac model 820-00163-A the problem that i faced was that the mac was working as in displaying condition but the OS was not working like loading bar was not completing to the end. Apple logo was displaying. The bios version that you sended the book is displaying but when we put the SSD, even the apple logo is not showing at display. And an error came and the display got blacked out. Error contains some kind of Chionese and English Language.Also we've tried all the bios versions that are present at your page.
My question is there is any universal bios for this model that contains zero error?
