More information in the manual would be better!

When everything has actually worked out perfectly. However, on my MacBook Pro in late 2012 the screw is broken, with which you can remove the piece of metal above the drive. Unfortunately, the screw was sitting so firmly that the screwdriver has so burdened the screw that milled in the screw was no longer intact. In other words, the screw could not stop turning. That's why I had the metal by sawing to remove the CD drive. This notice and a warning in the manual would have been very helpful. Maybe you can still grudge. That's why there are 2 star deduction.
