Hi there,

Thanks to your help my system is now stable, I would just like to mirror real iMacs and enable iGPU (headless) so that I can use Sidecar etc.

In order to achieve that, do I just add the following to the DeviceProperties section of the config plist :

PciRoot(0x0)/Pci(0x2,0x0) : ig-platform-id : <Data> : 0300923E

and then boot into BIOS and enable iGPU, saving and resetting NVRAM or do you recommend to do it using another method?

Thanks!

Do you want to enable SideCar using USB or over Network?

Hmmm I always had it working both with USB and over network using the above method but if I need to choose I'd say over Network

Cool. Yes, you need to configure the IGPU Device Properties, for a Headless configuration and you can have it enabled. Of course, don't forget to enable IGPU in BIOS. The DVMT should be set to 64MB.

Ok I made it work but...
When using the iPad connected with USB I have no issues everything is smooth but when connecting wirelessly the mouse pointer is very laggy and the iPad disconnects sometimes. I don't remember having this before so could it be a tweak to do within the plist or maybe trashing preferences and rebuilding the kextcache?

That could be even your Network too. Make sure to check ExtendBTFeatureFlags in your config.plist>Kernel>Quirks.

What's your WiFi Card?

Provide your new PR files to check further. Also, include VideoProc details.
