Syncing iMac and MacBook via MobileMe
 

My iMac and iPhone are working wonderfully. I fired up OF on my MB and copied the latest backup and that started off great. I went to the pref pane for syncing and went to select MobileMe, but all options are grayed out and I cannot sync. What do I need to do to sync my MB via MobileMe?

Did you configure MobileMe on the MB with your login credentials? If not, OmniFocus won't allow you to configure sync via MobileMe.

By the way, to extend OmniFocus to another machine, the best way to do it is to simply configure sync on the new machine and do a sync. You'll be prompted about replacing your database and starting to sync, and once you agree, you're off to the races. However, if you copy your database over, make some changes, and then try to set up sync, you may run into difficulty.

That worked
 

Had to log out and log back in using System Preferences and then it synced right up. Thanks for the help!
