In other news, I've successfully moved an irritating doctor appointment from tomorrow to June. I just didn't need that this week.
Let's see, what else have I done?
I successfully fixed the non-syncing of text messages between phone, iPad, and Mac -- without changing a thing. I just selected the Apple ID settings on all three devices, gazing at them lovingly for a minute, and reopened Messages to find that...voila!... they're now in sync. This is something that just happens now and then. I'll find them not syncing, and then they sync. Ridiculous, no?
