mac book pro boot problem
Hi,
i have the same problem as the one described here:
MacBook Pro, late 2011, OX10.12.4, boot problem
the only difference is that after the progress bar with apple logo i got a grey screen and after the mac book pro fans make a lot of noise, the mac book pro is over heating and it shutdown itself , sometimes it does not shut down and i had to do it myself, strangely windows is no more booting ,shutdown itself also, i have a triple boot on the same disk with linux installed and it still run nicely under linux for 3 weeks...
i also can no longer make a network install cmd -R cmd -option R it downloads the OS from apple and start making a lot of hyper ventilation with the fans ,seems to over heat, and shutdown securely...
i had an install boot disk from external hard disk and it does the same that with apple network recovery...
since 3 weeks i can not find any solution to boot again Mac OS X (or windows which is unable to solve errors) , any idea? (Linux still running well, so my Mac Book pro is now a linux Box !)
at the very begin the problem was solved by disabling some extensions, for a while the system started but used to freeze until it no more start, when i run the apple hardware test by network boot (this ones works) it passes all the test even in extended mode (check all the memory) i have tested the hard disk of the apple partition with linux badblocks command in read/write mode and it passes the test with no errors.
