SSD not detected by EFI
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)
- MacBook Mid-2010 (7,1)
Recently i have purchased 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
- 256 Gb HDD
- OS X El Capitan
- (Perfectly working)
- MacBook Mid-2010 (7,1)
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 EFI 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...
So i have installed another HDD in the MacBook 2 with high sierra and updated the EFI.
The SSD is still not detected by EFI.
I also tryed PRAM end SMC reset.
Last thing : In the parameters of High Sierra on the MacBook 2 HDD i can set the startup disc to the SSD (when i plug it in USB or SATA) but it's display "?" once it rebooted...
Many thanks for your help !
Sorry for my bad english.
(I have already posted the same thing on MacRumors forum but i think this forum is more technial)

Yes, the MacBook1 can boot MacBook2's HDD.
@deval82 :
Hum... I see... Maybe the EFI rom on the MacBook2 don't recognise the EFI partition on the MacBook1's SSD ?
I am going to try to install macOS High Sierra on the MacBook2 with another SSD to see first if it works, if not i will try your complete procedure.
Thanks you!

So, i think i have found the problem, When i install macOS High Sierra on my MacBook2 with SSD in HFS, it can boot, if i do the same but SSD formated in APFS, it's not detected.
Now i need to know how to enable APFS on the MacBook2...
I am sure it is possible because the MacBook1's SSD is in APFS and work great on it.
Do you know how to enable it ?
Thanks you !

You don't need to swap the HDD for a SSD, just run the High Sierra OS installer on the system.

@yojx21 - You can also compare the EFI versions between the two systems to make sure its at the correct level. Its found under the Hardware Overview section when you click on 'Hardware' header.

They don't have the same EFI version, i don't know which one is more recent... Do you know how to know that ?
Yohan さんによる
Give me your version numbers (both)
