I read on macupdate that some of their users claims that the new update for intel models are making their hardrive whirl a bit? I know mine has been acting up as of late (similar to my external hd lag.. then starts whirlin) so I don't know if I should update it. btw the link is listed below. i might not be 100%clear on those guys' comments (and replies). http://www.macupdate.com/reviews.php?id=21487&pid=147446 some problems they said were "photobooth won't force-quit anymore" and stuff. has anyone updated and can they tell me if their whine has decreased or any positives/negatives?
