AppStore and iCloud aunthefication problems (maybe hardware related things)
Hi. I have MBP (2006) with broken ethernet port but working wifi. I never woried about it cause I've used wireless everywhere.I had the interface "Ethernet" in the list of interfaces for years but MBP has not seen any cable plugged into it.
But after update to 10.7.x (I didn't really noticed when it had happened) ethernet interface has been missed from the list of interfaces. And at the same time AppStore stoped to work with my apple id with the message "Your device or computer could not be verified. Contact support for assistance". And now after starting iCloud services it doesn't work too: "This Apple ID is valid but is not an iCloud account"
My apple id is ok, I've checked it 4 times, everything is verified, I can buy applications and music at iTunes Music Store, authorize and deauthorize computers use it for iMessage on my iPad etc. iCloud works too on my iPad and at the website icloud.com — I can sync everything, backup to iCloud etc. But neither purchases at AppStore nor iCloud features works on my MacBook Pro.
I think its some eth0/eth1 related things, cause most of solutions for broken Apple ID on Macs are: "Remove /Library/Preferences/SystemConfigurations/* then reboot". I did it thosands of times but nothing happens. I tried to reset SMC but it doesn't work too — ethernet interface is still missing, AppStore and iCloud give me strange error messages and doesn't work.
MacBook Pro, Mac OS X (10.7.2)
