Just did the hack on my Air. It worked perfectly. Here are screen shots of before and after. I did not touch Terminal.

Good for you! I'm glad it also works on the MBA, I will put that in the threads title.


Did you get the file from a late (aluminum) MBP? What is the difference between the original file and yours?

The file (read: the package) comes from an early 2008 MBP. I added the four finger trackpad gestures for the non-unibody MBP's and early 2008 MBA's in the Info.plist in par with the four finger trackpad gestures for the unibodies (they are all in the same list).


worked great for me, thanks! questions: should i keep a backup of the orginal kext file and should i revert back in the event i need to take my mbp in to apple store for any service? thanks.

I honestly don't think that will be necessary. On the other hand it's never a bad idea to have backup. I still have my original file just in case I may need it in the future for whatever unforeseen reason.
 
I've been bitten by the 10.5.6 bug :(

Picture_1-20081216-103334.jpg


And I have one of the Multitouch Feb 2008 MBP's too.. Problem was, was that my trackpad/keyboard was replaced at the store a week or two ago, due to repairs, BUT I don't know if the top case or whatever part was replaced was for a Feb 2008 MacBook Pro, OR from the one before that.

So is there any way I can tell if the part replaced is the right one for the MBP? I guess what I'm saying is, that I don't know if it's 10.5.6 that broke the multitouch options, or that the store replaced the part with one for an older MacBook Pro.

And I assume there's an easier way to check without having to reinstall 10.5 and just install 10.5.5 before going to 10.5.6 ?
 
Were any multitouch gestures working at all before you updated to 10.5.6? If so, it's not a hardware issue.

Anyone care to speculate what will happen after performing this mod when Apple then release further updates?

- four finger swipe will be lost again?
- something even worse might happen?

that file could be rewritten if you install an update, but nothing bad will happen... it's just a single file.
 
I enabled the 4 four finger gestures,but doesen't work the 2 figer gestures (scroll).

Help please!

I have repaired permission before reboot my Macbook Air.
 
I edited my own plist in my original Kext and couldn't get 4 finger gestures to work.

Thankfully the kext i downloaded from this thread and gave me 4 finger gestures on my just pre-Unibody Macbook Pro.

Strangely enough i compared the file i edited in my original kext and the one from this site and they are identical. I can't figure out why it didn''t work.
 
Do you lose the 2 finger scroll? If so I will pass... for now... I love that feature.

Peace

I've tried to reinstall the 1.5.6 update but nothing changes!

help me please,now i re-install the 1.5.6 update...

someone can upload the original file?

I suggest you relax. Freaking out and posting for help every few minutes isn't going to help any, and will probably make people not want top help you.

I also lost 2-finger gestures after doing this "hack", but did a bit of research on the problem while waiting for help. Ended up finding out how to fix it before anyone was able to help me.

Try running the following command from Terminal:
Code:
defaults write -g com.apple.trackpad.scrollBehavior 2

Then restart your machine,

I have this working, but I edited the info.plist myself to include ONLY entries for fourfingergestures (not the secondary corner click). When you do this, the video demo in the preference pane has the MacBook Air Trackpad as an example, and not the new Alu MacBooks.

Furthermore, I didn't edit ALL the entries - just the ones associated with WSTrackpad2, which I assume are the entries related to my hardware (and possibly others too).

One final note - the Extensions.mkext file appears to be a sort of cache file for kernel extensions. Repairing permissions and rebooting is sometimes NOT enough after a simple edit - what needs to happen, I THINK, is that a 'change' has to be made in the Extensions folder AFTER the edits have been made to force a remake of the ./mkext file (for example if you make a copy and then make edits to it, this may not be considered a change). Or something.

Just notes on my playing around. Everything seems Ok so far...

You are absolutely right about ONLY having to include entries for four finger gestures. It doesn't make any sense to also include the "secondary corner click" rule for non-unibody MBP's and early 2008 MBA's.

I will edit will edit the Info.plist in the package attached to my first post as soon as possible.


Thank you for your insights!


(By the way, how did you know which WSTrackpad was associated with your hardware? And on the note; what is your hardware? Do you know with what hardware the other WSTrackpad are associated?)
