Pixelmator and Final Cut Pro X destroy my 13inch early 2011 2.7GHz Macbook Pro with 2GB of page outs. (I realise the laptop isn't best for these tasks, but a RAM upgrade is cheaper than a new laptop). I'm looking to upgrade the 4GB of RAM to 16GB or 8GB. Would doing so void the warranty? It seems like a fairly simple upgrade. I know to put the original RAM back in if I go to AppleCare. Also, the 16GB isn't officially supported, any issues with this?
