hi guys, my macbook aluminum 2.4ghz has been increasingly getting slower as of late, loading pages taking forever, mouse unresponsive when scrolling, beachballs all over the place etc. well, i have found a solution, i hope this helps anyone with the same problems. a while back i did a b/u from t/m ok. well ever since, my spotlight has been indexing sneakily in the background, using up cpu etc. i solved this by; enter sys. pref./spotlight/privacy, hit add button, add time machine disc. after this my mac went straght back to normal, fast,clean,smooth,etc. and NO BEACHBALLS! hope this is useful to somebody.
