    Hello all,
    I got a problem with not booting SSD.

    I have a first MacBook mid 2010 with the fellowing specs :

    MacBook 1
    MacBook Mid-2010 (7,1)
    Core 2 Duo 2,4 GHz
    8 Gb DDR3 Ram
    240 Gb SSD
    macOS 10.13 High Sierra

    (Perfectly working)

    Yesterday i have bought another one (exact same model) in better condition than mine:

    MacBook 2
    MacBook Mid-2010 (7,1)
    Core 2 Duo 2,4 GHz
    2 Gb DDR3 Ram
    250 Gb HDD

    OS X El Capitan
    (Perfectly working)

    So i decided to swap the rams and the SSD/HDD of both machine.

    And surpise :

    • The SSD of the MacBook 1 isn't detected by the Bios of the MacBook 2. Even when i plug it with USB adapter and press "option" key to choose boot disk.
    • The SSD is detected by Disk Utility on the Macbook 2 (with macOS High Sierra install USB Key to access Disk Utiliy)
    • If i plug the SSD with usb adapter in the MacBook 1 it works.

    What a strange thing...

    Do you have an idea ?

    Many thanks !


    (Sorry for my bad english ;) )

    The New machine probably needs a firmware update. I would recommend putting the old SSD back and Upgrading the OS. That should take care of the firmware too. Then you can swap the SSDs and it’ll probably work.

    So,
    I have tried to reset PRAM and SMC, it didn't work.
    I also installed macOS high sierra on a HDD i have put into the MacBook 2, and upgraded EFI manualy but the ssd is still not detected by the bios (in USB and internal SATA) but can still boot on MacBook 1...

    Any other idea ?

    Here is how i solved the issue.
    • In the MacBook2, i have installed another spare SSD i was having.
    • I have formated it in Mac OS Extended (Journaled).
    • Then i installed macOS High Sierra on it.
    • Once High Sierra was set up, i downloaded High Sierra upgrade from AppStore and ran it.
    During the installation, my EFI rom was upgraded and now i can boot MacBook1's SSD !

    Thanks you everybody for your help!!
