Screws on lower case look like Pentalobe not Phillips

According to this guide:

MacBook Pro 15" Unibody Mid 2012 Battery Replacement

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.

@yves_io if your computer is indeed a 15" MacBook Pro (Retina, Mid 2012) then use this guide instead of the Unibody. Dan is right with the P5 Pentalope screwdriver

Apple did alter things within this series some have Phillips others Pentalobe screws.

You'll need P5 Pentalobe screwdriver
