Recently I had the opportunity to repair the screen on a MacBook Pro. What an unbelievable nightmare! To get the screen assembly off of the computer, it took the removal of 46 screws in 8 different sizes including pentalobe and 3 different torx sizes. The majority of screws were under 1/16" in size and could only be picked up with tweezers. Just to remove the bottom cover, there were 6 screws of 3 different sizes. In comparison, I also just replaced the main board and battery in an HP Spectre X360- 3 different screw sizes (1 torx and 2 phillips) and a total of about 18 screws.
Here's a picture of the interior of a MacBook Pro:
