WARNING – These initial “point oh” releases, while perfectly fine for the vast majority of users, occasionally cause serious problems for a very small group of people. If you don’t want to risk being in this (possible) minority wait three or four days, by which point Apple will have likely fixed any of these bugs which may or may not exist. Before you upgrade be sure that you have a backup and that you have a few hours available to fix it in case something does go wrong. Which are probably good precautions to take in any upgrade, but particularly important if you’re gonna jump on these big updates immediately.
