Leopards been pretty good 2 me actually, but i am having a few problems with it right now. 1) Since i've downloaded Leopard, my PC, connected via wireless network, hasn't been able 2 print anything from my printer, which is connected 2 my Mac. 2) I have a Seagate 750GB external HD which i plan 2 use with Time Machine. The computer detects the HD, but Time Machine doesn't. Any suggestions? I'd appreciate it.
