Hi ya'll I've got my MBP for 2 months now, and I'm very satisfied with it. But now there's one problem, which is really annoying me: After a few hours of computer usage (say 3-4) I just need to restart, beceause the RAM is literally full. I know this normally has to do with applications, but even after a restart with no applications running, there's only like 1,5GB free (of the 4). I'm a Logic and Sibelius user, and both programs are RAM intensive, due this problem I can't even use them both at the same time. I'm sure 4GB needs to be enough. Thanks in advance, Niels.
