Mac Pro Missing Serial Number after SSD install
After installing a new SSD in an unused bay in my Mac Pro (OS 10.8.4) and setting it as my start-up disk with only System, Apps, Library and Users Folders on it, I have had a remarkable improvement in performance - things simply snap open now & I have not seen a spinning beachball/cogwheel until....
Messages will not work now - on opening, the program asks me to enter my Apple ID & Password but will not accept the entries (which I have double-checked & confirmed on my Mac Book Pro, iPad & iPhone) - I get a prolonged spinning cogwheel & then a message that it could not connect and I should check my Network Connections - I did & they are all working fine for other programs.
On line sources indicate that the iMessage Registration process involves the Mac's Serial number.
This no longer appears under the About This Mac Menu item when I click on the Version 10.8.4 line (the Build Number does appear).
This 4 year old Mac Pro has never had the Logic Board replaced.
And iMessages worked great prior to the SSD install.
Any ideas?
Thanks!
