NG7 Level 1 Level 1

After updating to OS 10.7.5, my Apple Magic Mouse stopped right clicking.


I logged in as root, dumped everyone's plists for the mouse, as well as zapped the pram, but still cannot right click.


Any ideas?

    I've had the same problem on my Mac Pro, except I'm using a USB Mighty Mouse... gonna try reinstalling Lion now.

    I reinstalled Lion, but it didn't work. Noticed that Time Machine backups were taking a really long time. So I then deleted the Spotlight index; however, re-indexing was estimated at '6 months' to complete!


    I wound up downloading Mountain Lion and performing a clean install (from a USB drive), it looks like that finally solved the problem for me.

    Hi NG7 & mustgroove,


    same story here.


    Right-Click on the BT Mighty Mouse doesn't work in 10.7.5 (iMac Mid 2007, clean install).


    It works without problems with a HP USB-Mouse.


    Hmm, no workaround

  • mustgroove Level 1 Level 1

    So one mouse works & another doesn't? Same thing with me - my USB Mighty Mouse (which is what was connected when I installed 10.7.5) has no right-click, but if I connect my Bluetooth Magic Mouse, right-click works fine...


    Weird that one mouse doesn't work but another does... especially since it's the Magic Mouse that's broken for the OP... perhaps the update breaks whatever mouse happened to be connected at the time the update was performed, but any mouse that's connected subsequently is OK?

    Should also mention - reinstalling Lion doesn't fix this. Still no right-click.

  • citrus101 Level 2 Level 2

    Yes, only the Mighty Mouse has a problem with the Secondary Button. The Secondary Button shows the same behavior as the Primary Button.



    No problems with the Magic Mouse.

  • citrus101 Level 2 Level 2

    @ NG7,


    did you enable the Secondary Button for Magic Mouse in the Mouse-Pane of System Preference?

  • NG7 Level 1 Level 1

    Yes, after purging all the prefs I went to each user on the computer and turned on the secondary click.


    Everything has been working fine since upgrading to Mountain Lion.

  • citrus101 Level 2 Level 2

    It seems to be a driver problem in 10.7.5



    You're right, no problems in Mountain Lion.

  • MadDogZ06 Level 1 Level 1

    I just updated to 10.7.5 and have the exact same problem (right click on Magic Mouse no longer works even though it is enabled).  I see no solution to this other than upgrading to Mountain Lion, which I do not want to do.



  • NG7 Level 1 Level 1

    Sorry to hear that you're having problems too.


    Since going to Mountain Lion the right click issue has become nonexistent; however, a few times now my Magic Mouse has been non-responsive (frozen) when I wake the computer from sleep. The batteries are good but the mouse doesn't respond… that is until I plug in my Mighty Mouse, then both mice work!


    I'm wondering if it's a Bluetooth bug that hasn't quite been fixed yet?

  • fongtl Level 1 Level 1

    I face the same problem here.

    Clean install 10.7.5 and using wiressless mighty mouse

    No secondary click right now...


    How can I (we) solve it??

  • earlduke Level 1 Level 1

  • RG777 Level 1 Level 1

    USB Mighty Mouse don't work with my Mac Pro too. Only left button is working after installing 10.7.5.

    Very annoying fact.

    Any solutions?
