Hey – While I am able to sync consistently, through DropBox, between my MacBook Air and my iOS devices, if I attempt to sync my Mac mini with DropBox, I consistently get a crash. I have even replaced my Accordance Files on the mini with what I have on the Air first and then attempted a sync, and I still get a crash. Mike Garrity offered to chat via Jabber, but I was never able to see him on my Buddy list – probably my fault. I Message on my computer, but I don't think I've ever used Jabber. I probably set something up incorrectly.
Anyway, when you get an answer, I'm hoping it will help me, too.
