Q: iMac sometimes ignores left click

It's fast user switching. At least in my case. I *never* have the problem after a reboot. Once the user account has been switched, the problem will not go away until I reboot again. I've been able to get it very reproducible.

I set it on 8 dash

God, it seems to be working. If that really solves it then I owe you a drink.

I've been struggling with this problem for a while and it really hinders workflow and increases my blood pressure.

Okay

Had the same problem, i quit mplayerx and no more dead clicks anymore, will update if anything changes

hello everyone just created an account to show you what i found.

i too have had the left click issue and followed some advice of a clean install.

the left click issue is still present, take a look >

I had the same problem.

I did everything clean install new mouse hit the magic mouse on the wall with no help.

What helped me is to in setting accesibility uncheck the Enable access for assistive devices. A third party application was abusing up this.

I am happy with an old mouse now:)

Well, after reading this post I pulled out my USB bluetooth adapter (which I was only using for a bluetooth keyboard), went wired and problem solved!  I don't even want to try plugging it back in to test my theory; just happy everything's working again; it was driving up the friggin wall for months now.

Thanks for the tip!  Good luck to everyone else still dealing with this.

****!  Nevermind.  Seemed to stop for a while, but started up again recently.   Things are sucky again.

OK, so for anyone who's experiencing this issue and is running the "Typeit4me" text correction and expansion utility in the background,TURN IT OFF.  For some reason it seemed to clear the issue right up for me.  I was hesitant (and still a little shakey) about posting this since the last time I posted what I thought was a solution turned out not to be.  But I've had no click issues for almost a week now since turning that program off which would normally be running in the background.  I'd be interested to know if this solves anyone elses left-click issue.

omg, someone said "shut down spotify" and that works for me like a charm... realy thanks guy! realy thanks!

so, dont forget to uncheck the "open at login" option on dock. for sure i double check this on spotify options, and are still turned off too... btw i turn off "Allow Spotify to be started from the web", no more annoying click problems!

cheers!

I have the same problem. How can i solve this? Any idea?

{{{ POSSIBLE SOLUTION }}}

I was having the same problem. Here's the solution that seems to have solved it for me:

Go to: Apple Icon > System Preferences > Mouse

Then reduce the "Double-Click-Speed" for the left mouse button.

I had mine almost all the way towards "Fast" and I slid it back to the center, and that seems to have done the trick. We'll see..

Same  problem, random left clicks, I read this thread, did all the reboots, clean install, accessibility stuff, etc., to no avail.

Some people got rid of spotify, and it solved the problem, but I don't have spotify, but did recently add the safari exstension curiyo, uninstalled it an problem solved .

Thank you!  This solved my problem.  I must have accidently changed the mouse speed button while holding my mouse.
