Of course it worked now, I'm just too 1337 and i pwn this laptop. Another installer I downloaded was about 300mb then simply said it couldn't find the files to install, i.e. the package was broken. That's equally stupid.

I also have a Macbook Pro and I had to keep watching out with fucking Software Update making sure it didn't install the Leopard Graphics Update 1.1 which crashed my pc all the time :( Not exempt
