  1. Pattern of MLB (Main Logic Board)

    Not always. On current hardware ROM is a subset of Thunderbolt MAC address with some additional specific characters. Older hardware can have ROM derived from either Ethernet or Firewire depending on model. I was using apple derived genuine MLB and ROM from a non internet/iMessage connected Mac Mini.

    Five days later and it's still not working.
  3. Pattern of MLB (Main Logic Board)

    I simply used the MLB/ROM values and created a new UUID incorporating the ROM values, all had been well for months until the inability to send messages occurred yesterday morning. I'll try to log back in after three days and see if it has resolved. Was using a 13 character MLB with a newer iMac 14.1 system definition

    Ok - got "disconnected" from iMessage this morning although it still shows as logged in. Used real values from a non internet connected mac mini media centre and it had been working flawlessly for ages until today.

  6. Pattern of MLB (Main Logic Board)

    Interesting. Only a partial match with my ROM and slightly less than yours...
  7. Pattern of MLB (Main Logic Board)

    I'm typing this on the wife's MacBook Air 6,2 and can confirm that the ROM on this machine bears no relation to any of the network interfaces: WiFi, Bluetooth PAN or Thunderbolt.
  8. Pattern of MLB (Main Logic Board)

    I have managed to extract a bunch of 13 character MLB/ROM values from older macs and some of the ROM results are a bit garbled, however they are all based on the Firewire address with the middle hex pairs removed. Run this command in terminal to get all the MAC values of the network adapters, the ROM will be the Firewire one. networksetup -listallhardwareports

    nvram 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14:ROM and nvram 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14:MLB

    Was only a matter of time. However it's back up and running using the ROM/MLB of my media centre mac mini which never connects to iCloud.

    ... And as if by magic I have now been remotely signed out after 5 weeks.
  12. Pattern of MLB (Main Logic Board)

    Yes this is the most likely case. I have completely non-standard made-up MLB and ROM values and after contacting Apple support with the error code they were succesfully paired with my AppleID. They may have implemented tighter controls now.

    I have been using my own user generated SN, MLB and ROM using only the basic Clover guidelines from last month and it works just fine so far. Updated to 10.10.1 and can sign out then back in to iMessage with no problems. Had to phone Apple with the customer code about a month ago when first updating to Yosemite + Clover but fine ever since. I wonder if the Apple agent "added" my user generated variables to his database or perhaps am I living on borrowed time and will eventually be signed out permanently...?

  15. Ok that makes sense. My DVD Player app was not working and throwing an error as it thought the internal DVD drive was external. I fixed that problem by editing /System/Library/Frameworks/DVDPlayback.framework/Versions/A/DVDPlayback with 0xED app and replacing any reference to "Internal" with "External" My DVD drive is on the Intel ICH10 AHCI controller, what bad things will happen to my HDDs if I change it to ESB2?
