Question: Secondary click in Lion, Macbook Pro 4,1

I have an early 2008 macbook pro (Macbook Pro 4,1).

In Lion, the only way to right-click is using ctrl+click. If I select "Secondary click" in System Preferences/Trackpad, it gets automatically un-selected when I exit System Preferences. This is very frustrating. Any idea how to fix it?

Macbook Pro, Mac OS X (10.7), MBP4,1

To workaround this problem on older macbooks, open Terminal.app from /Applications/Utilities/ run following command:

defaults -currentHost write -g com.apple.trackpad.enableSecondaryClick -bool YES

then log out and log back in (to disable secondary click pass NO instead of YES as the last argument).

OK I have found a fix. I'm sure it can be done better than this, but:

1. move your Library/Preferences folder to Preferences-old

2. create a new account and copy its Library/Preferences folder to your library

3. move back the non-apple pref files from Preferences-old

I've got the same computer and the same problem. I hope it's a bug and fixed soon. I've had lion for an hour and it's already driving me up a wall.

I've also noticed that if you go to trackpad preferences -> Point and Click and just put the mouse over the option for the secondary click, the demonstraition video doesn't change. If you had the mouse over the tap to click, the video stays as that and if you had the mouse over the "Look up" option, the video stays as that.

I also noticed that is doesn't let you keep the selection for the secondary click. If you allow that and close system preferences (not just go back to "show all") and then open systems preferences and look at the secondary click option, it's unchecked.

There's no way to make it stay checked.

Add my name to the list. This happens with ALL 15" Macbook Pros 4,1.
The 17" Macbook Pro 4,1 is immune, and the 13" Macbook Pro didn't exist at the time.

I work for a University, thus we got Lion early for testing purposes. It was obvious on July 1st that this was an issue, and so we posted on the developer forums about it. Got several replies from other developers with the same laptops that have the same issue, but no official response from Apple.

Bought Lion for my personal laptop today (which happens to also be a 15" MBP 4,1), and the issue still exists.

So, I should think Apple is aware of it by now. Hopefully it is fixed in the first round of bug fixes.

Strange. On all nine Macbook Pro 4,1 15" laptops the secondary click wasn't working. But on the two 17" MBP 4,1 laptops, the right click was working, but here people are saying they are having the issue with the 17" and the Air version as well.

Perhaps I am mistaken and the 17" MBPs are the 5,1 MBPs and not 4,1. I know they were bought in 2008, but I can't remember if we got the 17" MBPs at the same time or after the 15" MBPs. I'll check tomorrow.
