To learn how to exchange there on any Mac running -
"Apple / About this Mac / More information / storage / instructions for memory upgrade"
So it is quite normal and Legal without warranty loss the memory to change the Mac.
They were replaced in about 5 minutes.
Mac Book turned on, booted without problems, new Ram was immediately recognized. The speed increase is partly white already enormous, clicking eg to iTunes, the program has opened before you release the mouse again ... awesome, a lot more fun.
Internet works by this upgrade but not faster, for most people anyway logical (for me), should be at this point but said sometimes.
For all games friends on Facebook (Zynga) you need to know but that 8GB Ram may already be an improvement, because these are indeed reproduced in Flash Player is installed on the computer. The experience I've done at least.
All in all - upgrade for the money!
5 Stars!
