I have the same issue. I have both my iphone and Mac syncing through my server (mac mini). But I can't find any option to automatically sync when I shut down Omnifocus on my Mac.
I assume if I shut down my Mac half-way between the default hourly sync, then that info won't appear on my phone until I reboot the Mac again and it gets a chance to sync.
I assume there is a way to set the sync intervals, but being fairly new to Omni, think I am missing something quite simple.
Any help is appreciated.
