wednesday night i sat down in front of my iMac (still running snow leopard). there were 9 available updates. i ran them all and now i'm having a few problems. mail will not connect to my mobileme account and i can't find my appletv 1st gen in the device list in itunes. in fact, i can't find the device list at all. my atv 2nd gen finds itunes fine but will not stay connected. it will stop halfway through a movie and tell me that i need to turn home sharing on in itunes, even though it is on. to fix it, i have to turn home sharing off and back on again. because i can't find the device list, i can't input the 5 digit code that my atv is telling me to put in. it seems like a big mess to me. i'm wondering if i should just update to lion and see if it fixes it all. i was kind of waiting 'til the first round of updates came out. any suggestions? thanks.
