I upgraded to iTunes 5, and also ran the latest Panther Security/System upgrade, and now my Finder, iTunes, and a couple of other random applications take ages (like about 5 minutes) to load.

One of the programs that took a long time to load (and appeared to hang) was Quicktime Player: I traced this issue down to a dodgy QuickTimeStreaming.component bundle: I’ve moved it out of the /System/Library/Quicktime folder, and now Quicktime starts up super fast.

I have tried the following techniques:

  • Repairing permissions. Apparently iTunes did have a file with dodgy permissions, but this wasn’t what was causing the slow loading.
  • Updated executable library prebindings. This did make every other app load much faster.
  • Cleaned the system and application caches. Again, other apps load faster.
  • Remove a heap of potential Finder problem cache files. I suspect that most of these were deleted by the above step, but I tried it again anyway. No joy.

I’m about to upgrade to Tiger anyway, so I’ll just backup everything and do that, I think.
