#8 Tiny screws

Apple’s obsession with making sleek devices also extends to using miniature fasteners. The iPad mini is held together by the smallest screws ever seen by iFixit. 

#7 Proprietary screws

The company uses unique type of screws, which require a special tool to unscrew them. One such screw that is used in MacBook and iPhone is called pentalobe screw. These screws are tiny, and without the proper tool, an attempt to unscrew them may cause damage to the device.

#6 Proprietary components

Most notebooks, even those with solid-state drives (SSDs), come with the feature to upgrade the memory if the user requires more storage space. With Apple’s MacBook pro, it is not an option since it uses a proprietary drive.   

#5 RAM soldered onto the motherboard

The latest MacBook Pro notebooks have a RAM which has been soldered directly to the mother board. This means that the users are not allowed to upgrade Ram once the device leaves the factory.
