Wired Mighty Mouse acting like single button mouse

I had the same problem with my Mighty Mouse.

I fixed it in the following way.

1. Install "USB Overdrive".

2. Set up the right click.

3. Check the right click is working.

4. Enable the "USB Overdrive". (checking option "Enable")

5. Set up the original mouse preference.

6. Check the right click is working.

7. Uninstall "USB Overdrive".

Hope this helps.

I've just tried USB Overdrive to fix the problem - I can get right-click to work as soon as I install USB Overdirve, but when I uninstall, I'm back to square one.

Have you tried the mouse on a different Mac? It might just need to be retired or a bug with the latest Mac OS X not thinking about older mice (in your case try an OS update or a recovery boot to isolate OS issues).

i've tried it on my mac book pro and right click is fine. Also, if I leave USB Overdrive installed, the mouse functions correctly.

Hmmm... Looks system specific. If you do a recovery reboot on the problematic mac and check out mouse functionality does it work? 10.7.5 was the last OS X Lion release. Do you remember if it worked under 10.7.4 release? 10.7.5 was patched in Sept 2012. Is your Macbook Pro running 10.8?

Both run 10.7.5. The Mac Book Pro was upgraded in two stages: firstly the original 10.7.5 and then I applied the supplemental update to 10.7.5. The iMac was upgraded to the original 10.7.5, then rolled back using time machine to 10.7.4 (I couldn't cope with my main machine on the original 10.7.5 with the time machine issues). I then applied the fixed version of 10.7.5 (which included the time machine/index fix). However, I then discovered that Time Machine was not backing up the recovery parition because I no longer had one on the iMac. This presumably arose because the restore to 10.7.4 did not restore that parition. The approved fix for this was to reinstall 10.7.5 on top of the 10.7.5 machine to get a recovery paritition. At that point, right-click stopped working! All of this was caused because of the faulty 10.7.5 release😕

You willing to bite the bullet and upgrade to 10.8?

I'm not sure why the 10.7.5 works fine with your right click wired mighty mouse on the Mac Book Pro, but not on the iMac, but if the timeframe of the 10.7.5 updates & time machine issues aligns with the loss in functionality then I think you've narrowed down the possible culprits.

Good luck on a OS X upgrade or reinstall. When you get it working again repost so anyone else running into this will benefit from your pereserverance!

Same here. Installing USB Overdrive restores the right-click function, but uninstalling breaks it again.

I've submitted a bug report to Apple on this issue.

Works for me.

hey,

I just talked to German Apple telephone suppert. They fixed the problem for me! With fresh installs of 10.7.5 the problem is, that two files are missing that are needed for the mouse. In my case I could get them from another computer I own that ran Lion and did have the files. To get to the files you need do this:

Go to

/System/Library/LoginPlugins/BezelServices.loginPlugin

control-click that file and choose "show contents"

now in the finder window navigate to

Contents/PlugIns/

In this folder should be two files named

AppleBluetoothHIDMouse.plist

and

AppleHIDMouse.plist

If you don't find these files, you need to get them and put them in.

Till's solution was the right one for me. 🙂

USB Overdrive works too, but don't last after uninstalling it.

Ok, excellent for finding the root of the problem.

Now, where can I find those files, of course, I don't have them.

Do you know somewhere to download them from?

Thank you. Regards, Charlie.

Till's solution also works with the same two files copied from Snow Leopard (10.6.x).

FIXED! Not sure if this is still a hot topic but I recently unpacked an Apple Wireless Mouse which had been unused for a couple of years and tried it on my MacBook Pro running 10.7.5. The right-click function didn't work. I checked for the system HID files, as advised by another poster, and mine were complete. I tried curing the problem with USB Overdrive and that didn't work either. No function whatsoever could be assigned to the right click.

Then I found the 100% workaround.

Instead of letting my middle finger rest on the mouse (on the left-click area), I lifted it up in the air so that it wasn't touching the mouse. Eureka! Right-click worked.

Just occasionally, I also needed to lift up my 3rd finger as well - from its usual resting place down the left flank of the mouse (I'm left handed).

So, now that I know there is a flaw in either the mouse design or my finger, how can it be properly fixed? Should I ask Apple for a new mouse? Or my maker for new digits?
