Enable 4-Finger Gestures on an Early 2008 Macbook Pro/Air
Just a quick post for MacRumors + OSX Hints forum members, that will hopefully save me from typing out these instructions a bunch (more) times.
If you have an early 2008 MacBook Pro, or a Revision A MacBook Air (like me!), it was recently shown that they can be hacked to support the 4-finger swipe gestures of the October MacBooks and Revision B MacBook Air.
Unfortunately, the original hack required you to reinstall Leopard, using an installer CD from one of the newer MacBooks, and was also quite complicated, involving editing .kext files and fooling the Leopard installer into thinking you had a newer MacBook.
Fortunately, with the release of OS X 10.5.6 the hack has become much simpler, and I'm happy to report that I'm providing an edited .kext file that will enable this on Early 2008 Mac Pros and Airs.
Instructions:
- Update to 10.5.6, via Software Update or you can also download delta and combo updates from Apple.
- Download and unzip the .kext file which is attached below.
- Navigate to /System/Library/Extensions/ and copy the file AppleUSBMultitouch.kext to a safe location (a backup copy)
- Delete the AppleUSBMultitouch.kext file in /System/Library/Extensions (You will have to authenticate).
- Move the modified .kext file from Step 2 into /System/Library/Extensions/. (You will need to authenticate again).
- Open Disk Utility (in Applications--> Utilities --> Disk Utility) and click "Repair Permissions" (This will take a while to complete).
- Restart your computer
After the restart, navigate to the trackpad system preferences pane, and 4-finger gestures should be enabled. With 4 fingers, swipe up/down for Expose, and swipe left/right to switch applications.
I've tested this on a Rev.A Air, and also on a multitouch MBP, but you should be sure to backup any critical files before doing this. If you have any problems, or want to revert to the prior state, use the original .kext file you saved in Step 3 above.

please help i cant find
please help i cant find appleusbmultitouch.kext file in system library extensions folder--does anyone know where it is? I have 10.5.6 leopard.
More faster? Don't repair permission, but...
...but all you need, for the point 6. (repair permission) is a simple and fast shell command. Open terminal in the dir /System/Library/Extensions/ and do:
$ chown -R root:wheel AppleUSBMultitouch.kext
It work fine for me.
Bye!

This is wonderful tips ;)

It worked well too on my MBP bought in july (an early 2008 model)
Thank you very much. :)
any idea what would happen
any idea what would happen if i did this to my Early 2008 macbook, the one without multi touch, the black one. i have a file that is called AppleUSBMultitouch.kext and i downloaded the one from here, could it really hurt?
Probably nothing, or worse
Your hardware doesn't recognize 4 fingers, so this won't work. I would say only BAD things can come about if you try it. If you decide to, please post and let us know what happened!
i
Hey mate! i did this yesterday 2 my MBP and i forgot to repair permissions :S now it won't recognize nor trackpad nor keyboard. If somebody makes this same mistake! Don't Panic! simply plug in an USB Mouse and a keyboard and repair permissions. LOL i feel stupid
Perfect
I LOVE IT !!!
Meet the prerequisites.
Follow the simple directions step by step.
Don't skip any steps.
And it works perfectly.
It's really quite simple.
Thank you very much !!!!
It Crashed
Done exactly what u says, and in order.
Now my MBA boots and gives me a login screen, but Keyboard and trackpad is no more responsive. :(.
Any way to recover?
BTW I have updated Mac OS X version. 10.5.6.
Superb! So far so good.
Superb! So far so good. Worked flawlessly.
