I am a little bit peeved that there was a glitch with the OS X 10.4.10 update and with the superdrive update and even the itunes update (at least I read there were issues). I switched to Mac 2 weeks ago and am quite happy with my Blackbook. I was used to seeing problems on XP with upgrades, but I thought this NEVER happened with Mac. Anyway, I am now afraid to just do the software updates that Apple recommends because who knows what will happen. Is this upgrade glitch that screwed up people's computers a common problem, or is this a once ever type of thing? Also, what if I never did the upgrade. If and when a 10.4.12 came out, do you have to do all the upgrades prior to, or could you jump from say a 10.4.10 to 10.4.12 without doing the step in the middle? Do people ever NOT do the recommended software upgrades? Anyone not doing Superdrive or iTunes upgrades? Thanks!
