You might have set an option that changes how your keyboard operates. Try these tips:
Choose Apple menu > System Preferences, click Dictation & Speech, then click Text to Speech. If "Speak selected text when the key is pressed" is selected, deselect it or click Change Key to select another key.
Choose Apple menu > System Preferences, click Accessibility, then click Keyboard. Make sure Slow Keys is turned off. If Slow Keys is on, you have to hold down a key longer than usual before it's recognized.
Choose Apple menu > System Preferences, click Accessibility, then click Mouse & Trackpad. Make sure Mouse Keys is off. If Mouse Keys is on, pressing keys in the numeric keypad moves the pointer instead of entering numbers.
Choose Apple menu > System Preferences, click Keyboard, then click Input Sources. Select "Show Input menu in menu bar." Choose the Input menu in your menu bar, then make sure the correct keyboard layout is selected.
You can see your keyboard's current layout on your Mac's display to make sure you're using the correct layout:
- Choose Apple menu > System Preferences, click Keyboard, then select "Show Keyboard, Emoji, & Symbol Viewers in menu bar."
- Choose the keyboard icon in your menu bar, then choose Show Keyboard Viewer. You'll see a graphical representation of your keyboard that highlights the corresponding keys you press on your keyboard.
