Moderators Jake Lo Posted June 10, 2018 Moderators Share Posted June 10, 2018 1) Replace PS2 controller with this one for Alps 2) What wireless device does it have? Intel is not supported and needs to be replace, See FAQ 3) Seems to be a common issue even for other iGPU, but could just be cosmetics only Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted June 10, 2018 Moderators Share Posted June 10, 2018 1) Look in /EFI/Clover/kexts/Other for any PS2 Controller kexts i.e..VoodooPS2Controller or ApplePS2Controller or ApplePS2SmartTouchPad Remove it and replace with one from the link 2) DW1510 is good for wireless only, no bluetooth. For combo, go with DW1550 3) Have not really look into it yet Link to comment Share on other sites More sharing options...
