Seonie,
Sorry I should have typed Contacts>Preferences...>Default Account>iCloud.
Yes I am, is this incorrect?
No, just trying to eliminate possibilities.
Using the 3 pane view, what Contact categories do you have in the left pane?
I only have iCloud with my sub-groups. No "On My Mac" contacts are displayed.
Do you see the + icon when you hover your cursor over "iCloud?"
Previously you mentioned that "it seems this is a widespread problem especially with iPhones 😟" Could you elaborate on that statement? How does it relate to Mountain Lion Contacts?
OS X Mountain Lion, iPad 3G, iPhone 4, 20GB iPod Color, iPod shuffle
