I want to be able to keep a group of contacts on my Mac only, while keeping the rest of them synched to iCloud (as they currently do).
A bit of background: I'm wanting to do this since I'm dabbling with a bit of scripting involving the Address Book, and I want to be able to create test contacts without disrupting my real Address Book, and risking the wrath of the sync gods. My workaround has been using a second account that only has local storage, but it's disruptive having to switch accounts to test something.
The Address Book preferences has an On My Mac account listed alongside my iCloud account, but I don't see any options when creating new contacts or groups for putting them in local storage. If I reveal the groups pane, new groups get put under the iCloud section, and I don't see any local/On My Mac section.
Is the On My Mac account a mirage, not actually accessible if you have iCloud enabled?
