Like I ve said, Mavericks won t work, only Mountain Lion works, Mav and Yos have the same error: won t let me get through the apple logo and my monitor goes to sleep.
As for the BIOS, UEFI won t work on my mobo.
I have installed OS X Mountain Lion about 2 years ago and now I can not install either Mavericks nor Yosemite.
Afer finishing with the logo at start up, my displays go full black and I can not see what is happening.
This particular problem occurred since Mavericks.
I have tried all...
