I had logic board replaced in august 2012 and question
Is there anyway to manually enter iMac serial number as I have been unable to sign in iMessage after the board was replaced. In "about this mac", all I see is serial number unavailable.
Thanks
iMac (27-inch Mid 2011), OS X Yosemite (10.10)
Hello ozzyemale,
Thank you for visiting Apple Support Communities.
That sounds very similar to this issue.
OS X: "Cannot connect" or "Cannot connect to the App Store. An internet connection is required"
Where it says:
The system serial number is used for authentication purposes. If the serial number is not displayed in About This Mac, the Mac App Store can't authenticate its connection.
- Choose About This Mac the Apple menu ().
- Click on the version number under OS X in the window that appears. The information should change to a build number.
- Click on the build number under OS X. The information should change to your computer's serial number.
- If no serial number is displayed,contact AppleCare for further assistance.
Best Regards,
