Left shift does not capitalize - Macbook Pro 13''

I recently bought Macbook Pro 13'' mid 2010.

From the beginning I can't capitalize letters with left shift key. Instead, with combination of most letters, it marks the words I wrote. I restarted shortcuts, it didn't worked. At the keyboard preferences, after pushing left shift all letters are disabled.


I'll be thankful if anyone could help me with it.

MacBook Pro, macOS Sierra (10.12.1), mid 2010

Hello Vito_PL,

Thank you for using Apple Support Communities.

I understand that the left shift key on your MacBook Pro isn't reacting correctly. I have a couple of things that I would like you to try to sort out on this issue.

First take a look at these two articles and reset the SMC and NVRAM on your computer.

Next take a look at the following settings in System Preferences to make sure that another feature or function isn't utilizing the left Shift key and that it's correctly mapped to your physical keyboard.
  • Choose Apple menu > System Preferences, click Accessibility, then click Keyboard. Make sure Slow Keys is turned off. If Slow Keys is on, you must hold down a key longer than usual before it’s recognized.

  • Choose Apple menu > System Preferences, click Keyboard, then click Input Sources. Select “Show Input menu in menu bar.” Open the Input menu, then make sure the correct keyboard layout is selected.

    To see the keyboard layout, click Keyboard, then choose “Show viewers for keyboard, emoji, and symbols in menu bar.”

If these don't resolve it, let's try testing with an external keyboard, either Bluetooth or USB.

We can also test in a new user to further isolate the issue. How to test an issue in another user account on your Mac​
