Screws on lower case look like Pentalobe not Phillips
According to this guide:
there should be 10 Phillips screws on the lower case. But mine look strangely like Pentalobe Screws. My 15" MacBook Pro (Retina, Mid 2012) was once serviced by Apple – could they have changed the screws? If so, what screwdriver should I use to open the lower case?
Any help or advice is welcome.
Is this a good question?
