After I upgraded to Mountain Lion, I noticed that apps have started asking for permission to access my contacts. Very cool.

When Skype initially asked for permission to access my contacts, I decided not to grant it.

However, when I loaded Skype this morning, I noticed that my Skype contacts screen was still getting populated from my Address Book.

I double-checked in the Security prefpane, and Skype still does not have permission to access my contacts.

How is Skype getting my contacts? Can apps access my Address Book even if I have explicitly denied them permission?

  • I'm not sure how Skype works, but perhaps Sykpe already imported the contacts into itself before, so it has them already? If you add a new contact into your Address Book does it appear in Skype?

As this was an upgrade install, you had used Skype already for quite a while, right? I assume that Skype is simply displaying its own database which it build-up before Mountain Lion.

I myself don't use Skype, so I just installed it and used my firewall to monitor what files Skype accesses:

During the setup I was also prompted by Mountain Lion if I wanted to grant access to my contacts. I denied access. If I had granted access to my Contacts, the firewall would have intercepted as a second barrier (I've set it up this way). But this was not necessary.

After several restarts Skype had written to ~/Library/Address Book Plug-Ins/, but your contacts are stored in ~/Library/Application Support/AddressBook. As you see in the first picture, Skype never gained access to my contacts.

And indeed, there are no entries in Skype's own address book:

So what you have probably achieved now in Mountain Lion is that Skype will not gain access to any new Contacts that you add to your address book. When Skype had access to your contacts in Lion, it copied them already and there's nothing you can do to undo that.

  • Makes sense. That's what I was going to say too.

    "and there's nothing you can do to undo that", well, you could just remove them from Skype.

    @vcsjones I bet Skype has copied them to its servers. Just like many other social apps. That is the actual problem :(

    Confirmed. I deleted the contents of ~/Library/Application Support/Skype, and my Address Book contacts no longer appear in Skype.
