How to fix Mac App Store error: "Your device or computer could not be verified. Contact support for assistance."

Many Hackintosh users running Mac OS X Lion have been unable to login to the Mac App Store, instead receiving the error, "Your device or computer could not be verified. Contact support for assistance." The verification issue appears to have affected the several legitimate Macs as well, though on less wide of a scale. There is no single, definite solution to this issue, but several possible workarounds are available. Read past the break to find out how to fix the error.

There are several solutions to the login error.

1. Go to /Extra in your main hard drive and open the text file org.Chameleon.boot.plist with TextEdit. This is the configuration file for the Chimera bootloader (which UserDSDT uses). Add this string to the part of the file between <dict> and </dict>:


Then reboot. If this doesn't solve the errors, proceed to the next solution.

2. Open org.Chameleon.boot.plist again. Add the following string:


If this string is currently set to 0, change it to 1. Reboot.

3. If neither of the above solutions fix the issue, open the System Preferences app and go to the Network section. On the left-hand column in the Network section, select each of the items and remove it by clicking the minus sign on the bottom of the column.

Then, go to /Library/Preferences/SystemConfiguration in your main hard drive and delete NetworkInterfaces.plist. Or alternatively, drag it to the desktop (as a backup, in case things go wrong).

By removing all of the Network items in System Preferences and deleting NetworkInterfaces.plist, you have effectively reset the network configuration for Mac OS X. Reboot (you may have to reconfigure your internet connection afterwards).
