Hi guys! Im new here so i hope i've posted this in the right section! Basically... i have a 2009 Imac 21.5" 3.06ghz with two problems 1) Time machine: It works fine! BUT! if i click on say google chrome if my time machine is powered down because its been inactive for 40 minutes it takes my mac about 30 seconds to load chrome up (or any application for that matter) and i know the two are related because i can hear time machine spin up when i click the icon. This is VERY annoying because half the time my mac assumes the app has crashed (which it hasnt, its waiting for time machine for some reason) And tries to kill it. What is going on!? 2) Ever since i upgraded to Lion my mac has been SUPER slow! slower than my old single core PC infact! every time i hit expose it takes about 20 seconds to give me a view of all my windows, Scrolling on web pages is painful, Copy and pasting is slower (not unusable though) I've tried repairing permissions and doing the daily, weekly, monthly terminal line to clear my caches etc NO DIFFERENCE! help please?! Replies appreciated!
