Mac OS X 10.10 doesnt recognize 1 and 3-finger gestures I have Macbook Pro 13" 2014. Everything was working fine. But suddenly it stopped recognizing some gestures.
I was always using built-in trackpad. But now my computer doesn't respond to tap or physical click. 3-finger gestures are not recognized as well.

A few hours before this, the computer was working fine. Then I left my laptop open for about 40 min. When I returned, it looked like the mouse button was clicked and stuck in the clicked state (I don't have a mouse, it is just how it looked like). Of course, I tried to stop it, but nothing helped... The laptop was unusable at all, so I just restarted it by holding power button.

When I connect a standard PC mouse, I get the same outcome - 2-finger tap, zooming, swiping work. But not clicking.

If I go to settings and set the secondary click to be the click in the right bottom corner of trackpad - this click is recognized.

Clicks are also recognized in login screen, but not recognized in recovery mode.

When I log in - clicks are detected, so I am able to log in. But it stops responding to clicks after that. Even when I log out, the clicks doesn't have any effect. I cannot login back!

I believe this is not a hardware problem and I can fix it as soon as possible.
But how? I cleaned it, performed reboots, cannot reinstall OS though - simply cannot click "next"! 

On the forums say that it might be a battery problem, but from the outside I don't see anything abnormal. And I cannot open the laptop and look at the battery.

How to make my laptop recognize clicks? Please, help me!

UPD: I added a few details.
One Queston, then my suggestion.

Did the machine respond normally to the mouse click?



Given your description of the issue, here’s how I would proceed:


Make sure your software and firmware is up date. Apple Logo > About This Mac.. > Software Update
Disconnect all peripheral devices. Hold down Shift at the boot chime to enter Safe Mode. If you can’t recreate the problem, it’s software related. The most likely culprit would be a third party driver that's interfering with your trackpad functionality. 
Run Apple Diagnostics on the machine. Do so two times, back to back, regardless of the result. The machine must be plugged into your MagSafe. If the machine is not plugged in, you may receive a false positive that there is an issue with your battery. If you do receive an error code, follow the on screen instructions. Make an appointment to bring your machine in for a definitive diagnosis and servicing. 
Follow these instructions to reset the SMC. Components such as the keyboard lights, fans, battery, power supply, and trackpad all rely on this controller. If one is behaving abnormally, a reset may do the trick. See if the issue persists. If it still does, then proceed to reset the PRAM. 
Make an appointment with Apple to bring the machine in for a free and definitive diagnosis. Remember, your machine is covered under warranty. The last thing you want to do is void that warranty. Especially when you can’t even pinpoint the problem. Simply unscrewing the bottom enclosure will void it if detected. So, do not try a DIY fix. Bring it in. If it’s a hardware problem, they’ll fix it free of charge. If it’s a software issue, they’ll proceed accordingly (see below) until the problem’s solved. No matter what the issue is, as long as it’s under warranty, they assume responsibility for fixing it until it’s fixed. I don’t mean to come off as preachy, but I can't stress this point enough. 
I see no purpose in reinstalling OS X before diagnosing the issue. It’s the first step Apple will suggest to take after the hardware checks out. Not before.  However, if you do so, I’d recommend a clean install (wipe the machine completely, then selectively restore your data). 


Best of luck.
