Replace internal SSD (faulty) with a new, which requires "macOS 10.13 High Sierra"
Hello
I have a MacBook Air (early 2015) A1466 with a faulty SSD.
Now I try to install the new one, but the new SSD is not showing up at Disk Utility.
(At Startup I pressed "cmd + r" to get into the Disk Utility).
In the description of the new SSD, it is mentioned that "macOS 10.13 High Sierra" is required.
So I installed the original mas OS (Yosemite 10.10.5) with the installer to an "external" USB-Drive.
Now it boots (very slow) but I can't make any update.
Because the system (macbook) from the Boot-USB-Drive is very slow, I downloaded "macOS High Sierra 10.13.2 Update" to an other USB-Drive.
At the beginning of the installation I get this alert message "this update requires macos version 10.13"
What can I do?
It cost me now 2 days of trying differnt ways.
Kind regards,
Frank
