Safari and Mail has been quiting, Logic Express keeps coming up with the error of not enough processing power. (Even when having just launched a new project and only put one loop on with NO processing! Even running a 7200rpm external harddrive!) I've got 4g ram on a 2.2Ghz macbook with about 80g used on a 120g hardrive. I've recently done erase and fresh intstall on the software, then migrated data from Time Machine. I've run disk utility, techtool deluxe and disk warrier. (No problems shown!) I've cleared internet caches, and just cleared disk space through disk utility. And guess what, its has just quit on Safari again. So I've Rang Applecare and got to get hold of Hi-tech support on Monday. Bit of a loss. In the meantime any ideas?
