When I upgraded to Lion, my macmini  started to drag. It seemed that  tis ball on the left was the basic cursor. Everything was slow. After some investigation, it seems that Lion needs vast amounts of memory just to run.

So I tried to do an upgrade.

My first call was to go to Apple store. Asked for the prices and their bits were gold made, since the upgrade was over 400€, wich is more than the computer itself.

More research was done and I found some memory chips from Kingston that were compatible. Amazon sells them for 37€, which is something more realistic.

The instalation was not really difficult. After umplugging the computer, turn it upside down, and open the round base, I was able to see the original chips. By pressing the two retainer clips to the sides, the first chip came out. After doing the same with the second one and I had reach half my journey.

The instalation is just  doing the same in the reverse order. Put both chips with a small tilt, press them down so they fit securely and then put the round plate back to the original position.

 Piece of cake. There are detailed instructions here.

After that, I restarted the computer, and everything goes fast as a rocket.

To be sure, and since I didn't use the official chips, I ran Rember, a program that do an extensive test on your memory. Everything was fine.

Im proud of myself
