Hi,my macbook pro 1502 don't boot in own os x (only bootable in boot camp windows),and i have only sound but don't have apple sign on desktop, and If i connect a HDMI cable go to tv display i have normal pictures and boot (in both of os x & windows).Noticable point is ;when i boot with option key ,ot in boot camp partision!!! Is there any body help me???(i don't access to official appstore ).
MacBook Pro with Retina display, null
shut down
disconnect all external devices and cables from the computer
Reset the PRAM reset pram
then reboot into safe mode Try safe mode if your Mac doesn't finish starting up - Apple Support
THX for your attention,but it didn't solve my problem.I try install new os x for my MBP,but again the problem remained.fortunately i touch withheld pressure on CLUTCH COVER and suddenly my display appeared and there isn't any problem after that!!!!!!!!!!!
I found my problem maybe happened cause of some pressure on my MBP during my recent travel.
My new question is ,need i replace some part of my MBP?
My macbook pro2013 only boot in bootcamp windows option
