What does "All on My Mac" mean?
I'm trying to get my head around how the Address Book works in Lion and iCloud.
A bit of background:
I have two Macs (Air and Mini), iPad and iPhone. I use iCloud to keep the address book in sync across the devices. On the iPhone, I also have an Exchange profile to get to a client's Lotus Notes Traveler email and an Exchange account for my work email. I also sync with my gmail address book on the Air. Thus there are many address sources.
I'm trying to understand what does and what does not sync via iCloud.
Based on a bit of digging about in the guts of my Mac and the iPhone, I can see that the address book is actually stored in a sqlite3 database. It would also seem that logically, all the address book sources are kept seperate.
Now, the question.
On my Air, the Address book groups page shows a number of sections:
All Contacts (pretty self-explanatory)
On My Mac
All on My Mac
iCloud
All iCloud
Directories
When I view "All on My Mac" it shows a slightly different set of contacts from "All iCloud". If I create a new contact, it is created in the iCloud Address book. So, what is this "On my Mac" address book? It appears to be the gmail address book, but I'm not sure.
If it is the gmail address book , how do I create addresses in it?
