OK. I got the idea. But... every time I log off, I have to execute the script? I dont like the ideia, I'm sure that there is a way to make this automatic but what if we just don't allow the system to create those files instead keep deleting them?

Well, in fact I'd love to install retail. But it is possible? I mean, how can I do that? There is a thread explaining ? Because every place I go, there's so many things to do like "install the distro, make sure your first boot are -f; then use the tool xxx for patch and then kext xxxx to that!"
I'm going crazy. I'd love to install chameleon or 123 and put the retail dvd, install the kexts and update. BUT HOW can I do that, using this hardware???

thanks
