I just got a new 27" iMac quad i5 ...running Snow Leopard and although I am generally very happy with the speed which it does everything ...I'd still like to 'squeak' out a bit more speed ...if possible ...without going the increse ram route right now. Can I trash the languages I don't need without messing up anything? Especially for my printer and scanner? Where do I go to do that? I've never been a big fan of Widgets ...so can I completely turn all of them off ...and will that help? When I do decide to increase my system memory ...do I have to replace the memory ram cards in pairs? Can I add a 4 GB ram card to just one of the slots ...and leave the other one at 2 GB? THanks in advance.
