A logic board failure forced me to migrate (via Time Machine restore) to an older Mac (each on 10.10.1). All other programs seem OK, but OmniFocus will not run (double-click OmniFocus.app in Finder, or click Dock icon linked to same). When launched from the Dock, the icon bounces twice and then … nothing. No warning, no dialog, no window, nothing.
Am in the middle of a very large project (a few thousand Action Items in OmniFocus). Would like to get OmniFocus working on this machine ASAP.
