Trying to do the finishing touches on an otherwise working build for my Dell 5290 Audio - ALC255 using Alcid=30 ALPS Trackpad detected as internal USB - ALPS Trackpad (HS02) does not work when VoodooI2CHID.kext is enabled. However, Touchscreen works as intended with Apple gestures. (I2C1@15,1) - Trackpad works when VoodooI2CHID.kext is disabled. However, Touchscreen does not work. Also, Cannot get Apple trackpad gestures to work. Can't get them both working together - Sound works (Speaker OUT, internal Mic IN) however, external LINE IN Mic does not work. Have tried using ALCPlugfix without success other than that it helped detect my headphones faster when inserted and ejected from audio combo jack. Was very delayed before. I've tried as much as I can to figure this out but would like some assistance wherever possible. Please help or link me to proper guides that I may not have come across. Thanks MacBook Pro IOREG.ioreg

Since the old voodoops2controller.kext no longer working on el capitan 10.11.4/10.11.5 So I took some time to get a new voodoops2controller for my Dell Precision M4800. This is version that merge of ReHabMan, bpedman. It also resolve the issue KP on el captain 10.11.4/10.11.5. Note: the version VoodooPS2Controller.kext20160602.zip need to be put on S/L/E please do not put this on clover or usb. Also try reboot with "-f -v" if you got KP. Update 2016 06 14: add more v7 for E7250/E7450/E5450 Updated version 20160620: supported MacOS Sierra VoodooPS2Controller.kext.zip VoodooPS2Controller.kext20160602.zip VoodooPS2Controller.kext20160614.zip VoodooPS2Controller.kext20160616.zip VoodooPS2Controller.kext20160620.zip VoodooPS2Controller.kext20160707.zip VoodooPS2Controller20160825.kext.zip
