10.6: Flip around (invert) the Magic Trackpad System 10.6
Snow Leopard only hintThe Magic Trackpad normally slants up to match the keyboard angle. Some may prefer to use it slanted down in their lap, on the couch, or on low desks with a gel palm rest. With this hidden pref, the trackpad auto-detects hand orientation from 5 resting fingers and rotates the coordinate system to match.

When slanted down, the mechanical button is at the front, activated by the fingertips instead of the thumb. If you don't like this, try turning on tap-to-click and 3-finger drag in the trackpad control panel. (You may then want the defaults write that moves navigation swipes from three to four fingers, displacing Exposť and application switch).

Type this in terminal:

defaults write com.apple.trackpad.orientation TrackpadOrientationMode 1

The orientation detection should become active after rebooting, reconnecting the trackpad, or changing other settings in the trackpad control panel. Just rest 5 fingers on the Magic Trackpad after turning it around and the cursor will thereafter move in the desired direction.

[crarko adds: I haven't tested this one. It has been suggested that the following command will work where the other does not. Give it a try and let us know. You will need to supply your admin password for this.]

sudo defaults write com.apple.MultitouchSupport ForceAutoOrientation YES

Sweet !
And I guess if you want to revert back you would use "0" instead of "1"?

10.6: Flip around (invert) the Magic Trackpad

Personally, I think it'd be best to just remove the preference rather than set it to zero. After all, I assume the original state was that the preference did not exist.

defaults remove com.apple.trackpad.orientation TrackpadOrientationMode

I can't get this to work. I set the preference (and checked it with defaults read) but nothing happens. I tried turning the trackpad off and on, changing a trackpad-related setting and rebooting the machine, but nothing worked.

Can someone describe what is meant by "resting 5 fingers on the trackpad"? Do I need to put the full fingers down or only the fingertips? Is the trackpad only inverted while 5 fingers are on the pad or does the 5 finger trick toggle normal and inverse modes?

Superuser default that actually works?
Authored by: sureshot on Nov 01, '10 07:08:08PM

Here's an alternate default that definitely works but will prompt you for the system's root (Administrator) password, and require reboot (or reconnect?):

sudo defaults write com.apple.MultitouchSupport ForceAutoOrientation YES

Turn the trackpad the way you want it then place 5 fingertips on it all at once, with them fairly spread out like somebody's taking your fingerprints.

You DON'T have to remove the preference to switch back to normal orientation. Just turn trackpad back around and touch 5 fingers again.

I can confirm that this second variant works. It doesn't need the other preference, too.

I can't get it to work either.

I think it would be great if you could hold the trackpad on it's side by the battery compartment and swipe with your other hand. That would be great for doing presentations.

Has anyone had success with this hint? It ultimately seems to have come from the same source as the previous hint about switching the navigation swipe from 3 to 4 fingers, and I can report that the latter works as advertised (it has been added to the Secrets database, BTW, for those using their preference pane (download link is near top right)). I can't, however, get any joy with this latest hint for the Magic Trackpad...

Try the sudo variant. There is no visible UI in the preference pane for this. It responds silently and instantly to the five finger magic.

Nice trick. Thanks... I had to reboot to make it work.
