Hi all A friend has just got a MacBook Pro and we are trying to chaging the stock 250GB drive with an SSD she's bought seperately. However, the problem is, the 250GB drive supplied with the Mac has 4 screws in the side of it that we cannot remove that the instruction booklet says to remove and install on the new drive prior to fitting it into the machine. What I want to know is, how do you remove these 4 screws, and why does the booklet tell you to just remove them without any information or tool to remove them? They aren't normally screws as my Philips head screwdriver doesn't work in them. Many thanks Michael.
