Of course this also means I haven't installed any updates in a while... I'm still at 10.3.2. I guess I should do a backup and give the ol' sotware update a run.

Kinda goes against my "if it's not broke, don't touch it" instinct; it even overrides my "have the latest update, or at least the next to latest update" instinct.
