it gets better...
It only gets better, I would advise switchers to repair permissions after any update or repair permissions before, learn how to diagnose your system, there are plenty of basic tools to assist you in this and you don't have to be a technician to understand its data, for example the Console logs provide a lot of good basic info, the Terminal app is great to and all you have to do is learn a couple of commands, also do not be afraid of researching your issue here on these forums and on the Apple site, I cannot believe that I will be posting the "sleep"issue yet again on these forums (which is to disconnect the battery from your laptop or disconnect your desktop, press the powerbutton for about ten seconds then reconnect,restart, other wise known as the PMU reset!) I was racing against this update to solve the connectivity issue and I did before the update was issued, the update was good. no known issues, works well on my mini and powerbook g4. There was a user in the Apple site that kept posting the same B.S on a thread about the connectivity issue and claimed that he did not need to try any hints or research any fixes since it is Apple's responsibility too keep his machine stable, "he demands the update now" silly Chamcox got the thread locked-out, he did not try any of the hints and I think hes still struggling, so avoid being like Chamcox an acute passive user, learn how to do basic trouble-shoot and do try the hints and fixes and learn in the meanwhile a new thing or two. Expect things to get bad once in a while with some update as well, but remember you have very good Mac users here in Macrumors willing to help.
