There are circulating so many instructions on the net, how is upgrading the memory in your Mac mini. I can present this type of armament only experienced computer users with Schrauberfahrung warmly. I myself have previously compiled my PC always independently. During the upgrade of the Mac I had but a little tremble and fear: The device is not designed for screwdriver, but for service technician with special tools. Yes, the instructions are useful, but that pry the shell with two spatulas, twist off the wireless antenna inside the housing, removing the fragile SATA cable and a few more things can be a really restless. For me, the remodeling has (thankfully) still worked without any problems and I have so saved a lot of money.
