Left-click not working on trackpad or mouse

My trackpad began malfunctioning suddenly. Instead of clicking, it would click + hold (selecting all text). Very soon after, left-click stopped working. I'm able to navigate with the trackpad, but the click doesn't register (the trackpad does physically click). Sporadically, I have some left-click function with the trackpad and mouse when the computer is awakened from sleep, but not always and never for very long.


When the mouse is plugged in, left-click doesn't register. I disabled the trackpad when the mouse is plugged in under Universal Access, but I still am unable to get the left-click to register with the mouse. I'm able to navigate, scroll and right+click with the mouse. I'm able to left-click when using the mouse keys.


My battery is in good condition (diagnostics were fine and it was replaced last year) and isn't swollen, which I know can be an issue that leads to trackpad problems. A technician saw no problems with the logic board. I am running OS X Lion.


Does this sound like an issue with the trackpad that will be corrected if the trackpad is replaced? Or is it another issue? If the trackpad is disabled when the mouse is plugged in, why is the mouse also having a left-click issue?

MacBook Pro (15-inch Mid 2009), Mac OS X (10.7.5)

If you are in the vicinity of a previously connected bluetooth input device, find it and turn it off, or remove it from your bluetooth pairings. Same thing happened to me, and a couple of days troubleshooting, I found that I had my bluetooth mouse in my computer bag. It was on, connected, and depressed in the bag, which interrupted the function of the trackpad.

I have/ had this problem to! I am not sure if I fixed it but it seems to work again.

I have my magic trackpad in the twelve wand (a piece of matching aluminum that holds the keyboard and trackpad together. But I think that the H-shaped small piece you have to put between the both presses the trackpad and that makes it disfunctional.


Do you use the want? Then remove the h-shape piece and see if it solves the problem!

I had this same problem until I figured out it was my fault. I got to work and opened my laptop but the trackpad wouldn't left click. I used the keyboard to restart and the trackpad worked for 30 minutes or so, then the left click stopped working again.


After cursing for a bit I realized the magic mouse in my backpack was on and the left click was being depressed.


If you're having this issue check to make sure you don't have a mouse on somewhere.

I just fixed the problem with the left click. I read briefly a recommendation that worked for me. Here is my experience.


Both my Apple magic mouse and my Microsoft mouse stopped working. Both are wifi. The left click was totally unresponsive on both mice. The right click was inconsistant, but I was able to somewhat maneuver it around, but not enough to work with. I noticed the track pad did work......strange.


The recommendation worked for me. It stated to turn off the unit. When it comes back on press the shift key until the rotating round circle will come up (not the beach ball). Eventually, under the rotating circle a strip will appear that starts to fill. Upon completion of the fill the computer will go black and come back on with a note that asks if you want to close or open the unit. Click open. Then, my desktop came back normally. Both my mouses work now. Everything seems to work like it should.

I am assuming that it is the upgrades. I hate those upgrades.

With apologies to those of you who have a hardware problem, I want to echo Joe's "doh!" moment, and propose that as a very first precaution, you turn off bluetooth. If it is a bluetooth device interfering, your trackpad and click should start working right away.


I rarely use my wireless mouse and kind of forgot about it. Found it buried under a clipboard which was ... DOH! ... locking down the mouseclick.


Embarassed by the time I wasted on this one!

My MacBook started doing the exact same thing; however, mine was a quick-just plain quit functioning. I also get a high pitched squeal that sounds like an extremely high-rpm internal fan. I seem to see everywhere that the closest match is power issues.


I found that the trackpad is also a similar issue- the internal battery lies directly below the pad, and has expanded to the point that a normal tap on the trackpad would not work. If you do a heavy click push (about four times harder) it worked perfectly.


Time for a new Macbook. Color me sucker for smarter computing and integration.

Thank you so much for this comment!!! My mouse was just driving me crazy that I could move the cursor around the screen and I could right-click, but nothing I did would make it left-click. I was able to use my keyboard to tab over to Safari, launch a new tab, do a Google search, and then saw your comment show up in one of the Google results. And guess what - My Magic Mouse that I use with my rMBP was turned on in my backpack, and was connected to my Mac Pro!


So thanks for the help!! 🙂

Dude, this was it! Earlier I noticed that my laptop worked just fine at work, but at home, the left click malfunctioned. I thought that was odd. I then read your post, and sure enough, my bluetooth mouse was on in the next room with a book on top of it - undoubtedly causing the left click. I'm glad it's now fixed. Silly mistake on my part. Great post on your part. Thanks!

It feels so good to be in the company of so many numbskulls! I was loosing it trying to figure out why my left trackpad button was not working. In fact I plugged in another mac keyboard and mouse. I could type, just couldn't click on any icons. Not even the login screen icons to select users. I zapped the pram. But If I plug in my wacom everything works....seemed odd. Thought it was a weird mac virus...cursing the fact I took of my tinfoil hat which left me exposed to cosmic rays.


Bluetooth Magic mouse!!!! Left ON in my laptop bag. Must have been depressed leaning against a chair. What a panic moment....whew! Wife actually solved this one for me. God I love her!


There is an accessibility setting that say's "ignore trackpad when bluetooth mouse is present". Mine was not clicked. I wonder if this is a bug. Seems like that setting should affect this issue.

Ridiculous. Had the same dumb problem. I have a magic mouse that was sitting in a bowl with some other electronics. My wife moved something in the bowl when I was in another room and then all of a sudden my left mouse stopped working.


found my magic mouse that had something lying on it and FREED it. boom, mouse starts working again.

I have no idea if this is already known, or if it will have any help. My mac is also doing this "no primary click thing" and i plugged in a USB mouse, wired, and have to use an auto clicker now.

My left click stopped working a few hours ago, and I didn't care much, I only use the comp for writing. I went into the System Preferences and went to "mouse" and there was a button to change my "primary mouse click" from "left" or "right", now i thought it was that the comp, or the mouse no longer registered the left click. How ever then I changed my "primary click" to the "right" my right click stopped working, and my left now clicked like the right up till that point. as the secondary click. which means my comp registers the click, but takes no action to prioritize the click.


I hope this will help someone figure this piece of s*** out, because i'm find i need a mouse, even for only writing, to change from one window in text edit to the next. or maybe im just to lazy to find a short cut that i ended up here typing this. who knows. I sure don't.


Still hope this info can be of some help.
