Henric, I'm really sorry for the trouble this is causing! I don't think we have enough information yet to determine exactly what happened - it sounds like some combination of changes in System Preferences (changing the sharing name of the Mac) and in OmniFocus' preferences are involved.
If you contact the
support ninjas, we'll be happy to investigate this further with you, though!
The good news is that OmniFocus for Mac backs up your data periodically - you mentioned you tried to revert to a backup and it didn't work, but just in case you tried some other sequence of steps, here's what I would recommend:
- Turn off sync in OmniFocus' for iPhone's settings for the time being, to prevent a recurrence.
- On your Mac, open this folder:
<your home folder>/Library/Documents/OmniFocus Backups/
- Select View -> As List from the menu bar.
- Click the top of the "Date Modified" header until the items that were modified most recently are at the top of the window.
- You can now double-click these backups to open them alongside your "real" data. You want to work backwards through the backups until you find the most recent one that was before the bad sync.
- Once you locate that backup, make a note of the file name - it's at the top of the window.
- Next, select File -> Revert to Database Backup... from OmniFocus' File menu.
- A new window will appear. Select the backup file you noted in the previous step in the file list. Once you press the "Open" button, OmniFocus will roll your data back to the state it was in when that backup was made.
It's important to note that any changes made after that backup will be lost, so be careful, but that should get you back to the state you were in before the bad sync. Contact our support ninjas at that point and we can help sort out what happened here.
