Ever since migrating to new iMac from an old Mac Pro, I used Time machine to restore all my stuff..Small errors started creeping in such as being unable to update stuff and now location services won't work..My question is I backed up this morning (errors and all)..I would like to restore to factory condition, but migrate my Mail and all its milboxes back to the restored OS...Will it do it..?? (Sierra to Sierra)..or should I wait until Monday and hope the new OS will over write all my scripts and permissions for the fix...??
