I have read this document [How To Upgrade RAM On MacBook Air] and know how to upgrade RAM on macbook air 2014. But I have a question about step 7-Change BIOS and Restore.
As the guide said,"The RAM of MacBook is bound with BIOS, so we need to change the BIOS and restore."
I have readback BIOS data before upgrade. Where should be change in the BIOS data. Can you give me more detail informations?
