My MacBook pro 2012 A1278 is taking all input like shift key is pressed. Like all letters in capital and numbers in special characters. But only when I am trying to login and typing my password. I can't login to it. Not taking any command also like reset command. And my mac's keyboard is fine. Please tell me what to do?
MacBook Pro 13″, macOS 10.13
Before going there...
If your mac sometimes starts in Safe Mode on its own, this is a clear sign that the problem is a physical issue on your keyboard.
You know, the way to start in Safe Mode is to... press and hold the SHIFT key. So you see, that's the problem.
Maybe something got in under the key, or for some other reason the mac is sensing the key being depressed.
Try attaching a USB keyboard when starting your mac - just as a test. Maybe you can borrow it from a friend or colleague for a few minutes.
See if you can type your password correctly using that keyboard.

What happens if you start in Safe Mode? Does it work while in Safe Mode?
Good job troubleshooting this.
By your description it seems something different. It looks like you may have accidentally activated “sticky keys”. Look in System Preferences->Accessibility->Keyboard and uncheck this.
It should not be difficult to find but I am not at my mac now to confirm the exact details. If you have trouble finding it let us know. I think we have found the problem.
It looks more and more like a physical issue with the key itself.
Maybe you should have your mac look at by an authorized repair facility.
In the meantime, you could run Etrecheck and post its full report here, just in case there is some weird software glitch.
That is not something that I am able to say, and most certainly not from a distance. It may be something that you blow away with compressed air, or it may that it is more complicated than that. In any case, we are talking about something that is somewhat fragile, so proceed with care.
Here it is in pictures - you want the box to be UNchecked, like this:
Yes sometime it starts automatically in safe mode. And my password id in capital letters, that's why I can login. But I want to hard reset it. And when I press Command + S, I can't give reset command because its getting everything in capital.
Hey! I checked my keyboard on virtual keyboard in my mac. And I saw there whenever I was pressing shift from my trackpad it was showing remain pressed and if I pressed shift again it was in normal condition. I was doing everything from trackpad. So, is it a software issue? Please help me because I want my mac for my programming classes.

Can it be done automatically by the system? Because I remember I didn't do anything like this.
Not exactly automatically, but if this box is checked, you may have done accidentally:
Hey Dude! I checked the problem you told me last time. But I didn't found this problem in my mac. There's something else happening to it. Sorry I m telling you very late, because I was out of my town and couldn't check the problem. Can you please help me further?
Hey buddy, I checked my keyboard in keyboard viewer. And you were right, one of the shift key is not working. It's the right one. Can it be solved by cleaning it? Because I don't want to change my whole keyboard just because of the single key. And the original one is not available in my area. Can it be done by simply opening the specific key and cleaning it?
Yeah! Lets pray for my beloved Macbook 😂😂. I'll see what can possibly be done to solve it. And thanks dude you gave me your precious time and for your suggestions. Because nothing precious than time it doesn't wait for anybody. Thanks again👍.
Can this problem be solved with installing a new SSD and new macOS?
Thanks for your suggestion. I'll try it surely. Whatever the response will be I'll tell you.
But will it work on terminal also? When I give Command (Command + S) so terminal starts. It behave same there.
But I will definitely check the problem you told me. Thanks again.
