Upgraded my macbook alu (late 2008) from 2GB of RAM, and everything went fine. Just 15 min for opening, removing the old modules, and plugin the new ones. Just make sure you read some instructions of how to do it, if you have never done it before.
The performance boost was incredible, at least for a user like me that abuses of multitasking.
Overall, it was the best electronic purchase I did in the last 2 years. Highly recommended!
