Hello,

I have done some testing and can now confirm that disable SSID on OS X, is not working as intended.

 

Have anyone else had this problem?

 

 

Test steps taken:

Fresh installed OS X El capitan.

CAT downloaded and installed.

It joins a eduroam instantly.

Confirmed that eduroam and ITU-guest was in the SSID list.

I then left campus and made a SSID called ITU-guest on my phone as a hotspot.

When I turned on the laptop, it joined ITU-guest.

Shut down laptop and returned to campus.

When starting the laptop again, it joins ITU-guest.


Hm, this is indeed not how things are supposed to work. The disabled SSID gets packed in the installer with the "AutoJoin = FALSE" property, meaning no device should connect unless the network is manually clicked upon. If you look at the installer profile, this is the snippet to look for:

        <key>AutoJoin</key>
        <false/>

The catch is: the files for iOS and for OS X are identical. If the disabling of SSIDs works on iOS (does it?) then there is no explanation for a different behaviour on OS X other than a bug in the OS.

Can you verify if the disabling works as intended on iOS?

Is this specific to El Capitan, or did you also test other versions of OS X?

At least Apple's doc is clear that it should work like this across all OS X versions:

"

Optional. Default true. If true, the network is auto-joined. If false, the user has to tap the network name to join it.

Availability: Available in iOS 5.0 and later and in all versions of OS X."


Greetings,

Stefan Winter
