Refined ALPS TouchPad driver

Recommended Posts

The PS2 controller kexts posted in our D630/D830 Mavericks bootpacks should do. They pre-date this thread and those kexts written by DrHurt.

I have a T440 with 3 button ALPS V7 trackpad.
I successfully installed MacOS with the help of anothers user clover files. There is one problem:

My trackpad is not recognized by the system with original VoodooPS2.kext. Only the 3 Buttons work and some basic functions - but no multi finger gestures.

With R6 ALPS Kext the gestures work perfectly... but no buttons because of the missing VoodooPS2Mouse.kext.
Is there any chance to edit the VoodooPS2Trackpad.kext plugin from the R6 zip to make it work in my original kext (look at attachment) - so that i have buttons working plus gestures?

VoodooPS2Controller.kext.rar

My Dell M4700 has Alps V3, I tried all versions of VoodooPS2Controller v4/v5/v6 RC, VoodooPS2Controller by Bronxteck, VoodooPS2Controller by RehabMan on my High Sierra but the system is still not fully recognize the touch pad, no trackpad found in Preference panel. I can still move the mouse cursor (very slow) with touch pad, using 2 fingers to scroll is fine. But tap to click and 2-finger tap to right-click doesn't work. I heard someone said that the system won't recognize touchpad without battery; unfortunately my laptop battery is dead and I'm using AC power so I cannot confirm if it is true.

If you have an Alps V3 TouchPad, you should have it in your System Preferences if you've set up your USB ports properly. I highly recommend you consult this thread which illustrate a recent experience with that version of Alps Touchpad:

 

Once you get your TrackPad PrefPane re-instated, you'll be able to activate items such as "Tracking speed" or "Tap to click" (which is not enabled by default).

Thank you for replying my post. As you said in another thread, I’ve tried either methods: update USBInjectAll.kext to the newest version + SSDT patch or using USBport.kext only. None of these method work. I can confirm all my USB ports are recognized successfully because I used USB flash drive to test every single port. The weird thing I’m encountering is: I can only use “tap to click” and “2 finger right click” in Recovery mode and at Logon screen (the step that we have to enter our password after apple logo loading completely). Once I logged on, “tap to click” and “2 finger right click” don’t work anymore. Because of these thing, I assume “tap to click” and “2 finger right click” are disable immediately once I logged on, I’m unable to open TracPad PrepPane to enable them also. I’m figuring out a way to enable these feature by edit file but still have no idea. Any of your suggestion about this problem is really appreciated. 

 

Update:

I was successfully enable trackpad tap to click by these commands (using terminal):
 

# Enable tap to click
defaults write com.apple.AppleMultitouchTrackpad Clicking -bool true

# Enable "tap-and-a-half" to drag
defaults write com.apple.AppleMultitouchTrackpad Dragging -int 1

# Enable tap to click for the login screen
defaults write NSGlobalDomain com.apple.mouse.tapBehavior -int 1

# Enable 3-finger drag
defaults write com.apple.AppleMultitouchTrackpad TrackpadThreeFingerDrag -bool true

Increase trackpad speed:

defaults write -g com.apple.trackpad.scaling -float 2.0
