I've just picked up a new computer and I'm looking for some advice on the best way to migrate from my old computer, which is suffering from numerous issues: Mail is an absolute mess. I have to input my passwords several times a week (sometimes for all my accounts, sometimes for some of them). Frequent hard freezes and sudden resets. There seems to be no rhyme or reason to when these happen, no common causes, etc. iCould syncing is extremely iffy. iWork documents can take days to show up, Clear (the RealMac App) syncing frequently shuts off. iMovie refuses to work with external libraries and won't export projects iMessage syncing is intermittent. Fan runs at full blast far more frequently than it should, and doesn't appear to be connected to machine usage (ie. Activity Monitor doesn't show anything that's hogging processor or memory). Numerous other small issues. I've heard things like "if it's a software issue, migrating will just put that issue right on the new computer," and obviously I don't want this to happen. I'm typically fairly handy at trouble shooting, but nothing I've done as fixed any of these issues for any left of time. I've gone through the usual PRAM reset, trashing preferences, and gobs of problem solving walkthroughs and nothing has stuck.
