After upgrading to 7.4.2 Air Disc won't connect anymore.
I recently updated my AEB to 7.4.2 and it turns out that my MacBook is not able to connect to the Harddrive connected to the AEB. When 7.4.1 was installed (and after downgrading Firmware to 7.4.1) it worked and I could even use it for Backups with TimeMachine.
It's a used AEB, bought on Amazon a year ago, or so. That's why I don't know when it was built etc. But the Model No. is A1143, if this helps.
Would be thankful for any advices.
