When i bought my mac at best buy the guy said more processes make it run faster, this was with leopard, with snow leopard, it is freezing when i am trying to send a video through email. it has been freezing alot lately and for the first time ever, applications have been not responding. has apple created the mac version of vista? should i down grade becuz ive been thinking about it, but if i down grade, will i lose all the stuff on my desktop, documents, itunes stuff, and like all my stuff on my computer? or do you think 10.6.2 will fix this?
