Further to trying to find info related to my issues with sleep/hibernation, I am just looking at various other sites related to USB, and I saw that the SSDT-EC-USBX-AMD.aml was designed for a Macbook7,1 or newer, and I am pretty certain that when I originally set this up, the guide said to select a Macbook 6,1.
Could this be the issue?
Should I have selected a newer iMac instead?
