If that's the case, you're in the group where, for unknown reasons, that rev of OS X, AFT and your Android don't get along.
I've seen that more and more without an easy solution because Google isn't updating AFT or because Apple updated OS X.
I really hate to send you for a paid solution, but you might want to look into this - http://www.sync-mac.com/android-sync.html
I haven't used that, so see if they have a demo or something you can try if you're interested.
BTW - have you installed HTC Sync Manager, and it so, is it working?
AFT is working for both phones (although the usb port on my gs2 is haggard and doesn't always play nice)
Sync manager pops up in a window every time I plug the One in, but I haven't set it up/installed it
