Hard Drive Not Recognized After Replacing Logic Board
I recently replaced a failing logic board on a 2011 Macbook Air. The install went smoothly, but on start-up, I get the question mark symbol indicating that the SSD isn’t being recognized. However, when I boot into Recovery Mode, it sees the SSD just fine and even lets me verify/repair. The hardware test also recognizes the drive and gives the computer a passing grade.
I suspect this is a firmware issue. The Macbook Air was running High Sierra, but I have no idea what the firmware situation was on the replacement logic board. I don’t know how to update the firmware if I can’t boot into the OS.
Any advice on how to update it?
