Macbook Pro 4,1 trackpad right-click

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

I have a 4,1 MBP and the secondary click preference is working fine for me. This was with both an upgrade of SL and the unsupported clean install of Lion burned to a DVD. I think there was at least one other person with a 4,1 MBP and we did not experience any issues with the secondary click using the built-in trackpad. And I believe there were a couple of people with older MBPs and I do not recall reading any reports of non-functioning secondary click. (Just complaints that they couldn't use gesturing.) So I do not believe Apple "doesn't care". But of course they are concentrating on machines that have the newer no-button trackpads, as gesturing is obviously easier on those since the trackpad is larger.


I'm not sure what preference file to check/delete. Hopefully someone who knows will post. I would suggest verifying/repairing your disk with Disk Utility, just in case it's a corrupted preference file. (I had similar experiences in the past.) Otherwise, all I can think of is a clean install. Either by clean install SL, then upgrade to Lion or clean install Lion.

I have the same problem.


Enabling Secondary Click in the Trackpad Options in System Preferences will select the option, but the next time I check in System Preferences, it got unselected again. And no surprise, double finger tap doesn't work. And the secondary click tutorial video is missing too.


Lion with MacBook Air 2,1 (Mid June 2009).


I've some additional info to add though:


1. The problem only occurs for one user profile created after the upgrade to Lion. Not another one and not the one which was migrated. I.e., other users can still two-finger tap!!


2. Therefore, a deletion and recreation of a user will most likely cure the problem. I don't think an entire clean install is in order. But I don't recommend to do this: As it may happen again and over again 😟


3. Even for the user profile with the problem, two-finger tap *did* initially work just fine. It broke some time after. Lion is the most current patch as of the date I write this.



I really suspect there is a glitch in writing some user preferences file. Anybody knows which file this preference is stored in?



And APPLE: please fix.

I just found a possible work around in an older thread here,

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


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).

I'll try it out and report back. But I can't check it right now. Maybe, somebody else can report back too.
