Ответ на "MacBook Pro with battery removed: strange behavior, no serial number"Well I did not give up and created a solution. These are the steps: (1) Get hold of the Apple Service Diagnostics DMG (ASD_3S162) for MBPr 2013 (2) Extract the ASD EFI DMG from within ASD_3S162 DMG and restore it to a USB stick (to make it bootable). (3) Get hold of the Blank Board Serializer (BBS) DMG ( v1.1 part number 063-07137) and mount it . (4) View hidden files in Finder (type SHIFT + CMD + . on the keyboard). Do the same to hide again later. (5) Copy the hidden Apps folder & the hidden diag.env file from the BBS to the root of the ASD on a USB stick. (6) Restart and boot from that USB and it will start the Blank Board Serializer App. Search the net for Blank Board Serializer instructions (and WARNINGS !) I rebooted and now About-This-Mac displays the Serial Number and I have access to iCloud, etc. My theory was that the original BBS’s EFI is too old for the 2013 MBPr’s EFI Firmware to boot it but the BBS App is not.

Ответ на "MacBook Pro with battery removed: strange behavior, no serial number"I have exactly the same issue as @Johnbon jovi described on my MBP Retina 13 late-2013. Serial number "Unavailable" Blank Board Serializer v1.1 does not boot off the USB on this MBP. The battery is now connected but the serial number is not back. Please do not suggest take it to Apple as it’s end-of-life and out of service contract. Was this issue ever solved ? If so how ?
