    Hello MacRumors,

    today I woke up starting up my MacBook Air as usual and realized that I have no internet. I have a MacBook Air Mid 2012 and use a original Apple Thunderbolt to Ethernet Adapter.

    In the Network settings it said not connected so I went on and checked several LAN-Cables, router, etc. Everything is fine. Under systesmreport it says that it recognizes my adapter so something else must be wrong.

    I checked every single thread on the internet and followed several solutions like deleting environment, preferences, settings etc. It only left me without the thunderbolt ethernet option. I am not able to add it back with the + sign, the option is missing. There is only a Thunderbolt 1 option which will not add to the interface.

    I attached a picture with how it looks now.

    I hope someone can help me with a solution to this problem.

    Sorry for my english...

    Kind regards

    Hello Weaselboy,

    thank you very much for the link you posted. It seems I have this problem even though it says iMac and MacBook Pro but I guess it is to early to call the group affected by this.

    The thread says that there was a silent security push. I really do not know a lot about Macs, but I always update my updates manually via the App Store. How can I see what is installed without my knowledge and is there an option where I have to accept everything before installing?

    Thank you very much.
