right click not working mountain lion

Since upgrading to Mountain Lion from Snow Lepard, my right click no longer works on magic mouse. I have checked the mouse settings and the right click has been selected. I have re-started, re-linked the the bluetooth connectivity and replaced the batteries. If I transport to MacAir it works fine, but if I re-connect to iMac it simply doesn't activate. Suggestions?

iMac (21.5-inch Late 2009), OS X Mountain Lion (10.8.2), Upgraded from Snow Leopard

Hi....control + click works as if I was right clicking....It's annoying, but the work around(control+click) will have to work for now. I know that the click is being picked up by the OS because if I go to desktop I can create a 'select' box by dragging the mouse. Doesn't seem to be regognizing the right click functionality though.

You're not going to believe this. The mouse is working now. Strange way though....On a hunch I logged in as guest user....It's the one I set up for vistors. When I did, it asked for iCloud logininformation. I skipped through and logged in. The right click was working on the guest account. So, I logged out and back into my primary account. This again prompted me to add iCloud information. I entered the information and logged in. The mouse is now working.


When I first upgraded to Mountain Lion I added this info for the cloud so, I don't know why it didn't take. I restarted and logged in many times when my mouse wasn't working and the OS never asked for iCloud login. I assumed it went through. I don't know if this is a glitch, but now it seems to be working. Thanks for all your help.

There are a number of posts similar to this. I recently experience my Magic Mouse losing its right-click function. I thought it was something wrong with the mouse itself. Coincidentally, I also recently got a trackpad for the iMac and the right click feature there wasn't working either, so I presumed it must be the iMac itself of the system software. I was already running Mountain Lion 10.8.3, but on a whim I donwloaded the 10.8.3 Combo Update from Apple and installed that over my existing installation.


Presto ! The mouse and the trackpad are now working. So happy.


Haven't really used a trackpad much with the iMac, and I do not have a laptop. I am actually starting to like it better than the mouse.


Liking the iPad Mini also. I works pretty well as a laptop when I am travelling, and if I carry the wireless keyboard and the trackpad with me with the iPad Mini is works pretty well as a little laptop. With all of the apps out there there is a plethora of gadgets, in some respects better than those available for the Mac itself.


I installed a little VPN thingy to give me access to my iMac at home, which is virtually always running, in case I need something remotely.


Parenthetically, I got onto all this because I had to bring the 27" iMac, only 1 year old, in for repairs, overheating with the fans running wildly. I kind of suspected that it was the CPU fan the SMC Fan Control thing indicated that my CPU fan speed was 0. That is what the tech said. Have to wait for the part to arrive yet though. Thank got for the mini. I miss my iMac.
