Ive been playing around with it - nothing important to report.
Just created the dsdt and trying to find a sys def that has the 3225 in. 13,3 seems to be the one but then the AlphaP's cpu script doesnt seem to include 13.3.
The real imac 13,3 has 4 usb3's and 0 usb2's.
Sound shows internal speakers and external mic.
Hardware overview currently showing iMac 13,3
Intel power gadget never shows the processor over 3.3 or any change in the GT (graphics clock?) which stays at 0.35
Temps have been ticking over at 36-38 and rising normally under load.
