Look, I'm going to be blunt here. A RAM upgrade is cheap as hell right now. If you can't be bothered to upgrade RAM - which is an extremely easy thing to do - then I think you should also quit complaining.
$20-40 and 5 minutes of your time, really that's all we're talking about here.
But why should I upgrade it, when it worked fine before? I do nothing different with my machine then did when it was new. Why should I suddenly upgrade then?
Mac2x, I just run the command and did everything you told me.
Also, is there some way I could tell OSX that Safari can only use a certain ammount of RAM? Like, set a limit of 500mb ram for Safari?
