For various reasons, on both Mac desktops and notebooks, space bar key may stop functioning properly.

Basically, there can be two reasons. It can be a setting problem. It is highly likely that, however, this is a hardware problem (a mechanical issue), especially if all of the other keys on your keyboard are working as expected. It is possible that the space key (bar) is probably sticking that you can fix easily.

And there are three ways to address and fix this problem:

  1. First, let us see if this is a setting issue. Consider adjusting your keyboard settings. Your Mac has various keyboard settings. So you can control how your Mac’s keyboard works. Try to adjust your keyboard’s “Key Repeat” and “Delay Until Repeat” settings. On your Mac, go to Apple Menu > System Preferences > and Keyboard:Mac Keyboard
    1. Key Repeat: When you press and hold a key on your keyboard, the key repeat itself. How fast you do want it to repeat? Changing this setting may help you. You can turn repeat off completely. Try this. Then type something to test the space key.
    2. Delay Until Repeat: You can also change the delay before a key starts repeating when it is pressed. You can also try to adjust this setting.
  2. If you think your problem is hardware problem, you will need to clean your keyboard. Carefully check beneath the space button, do you see any debris, bits of dirts, hair, various pieces of stuff?Follow the steps below:
    1. Turn off your computer
    2. Hold your laptop or keyboard upside down
    3. Tap the back side
    4. Give it a good shake while tapping
    5. If you have a keyboard vacuum, use it
    6. You may want to use compressed air to blow any debris out.
    7. Another cleaning method that we recommend is to sucking. Cover your space key with your mouth and suck.
  3. If nothing above works. Contact Apple. You may want to make a Genius Bar appointment. If your Mac is still under warranty, Apple will fix this. If you are not sure, you can check the AppleCare warranty status by going to Apple’s check warranty page. If not, consider replacing your keyboard because it is likely that your keyboard is defective and needs to be replaced.

You may use these tips if your keyboard is typing every letter twice, not just the space bar.

  1. The method of covering the space bar with your mouth and sucking is extremely effective. Make sure to find someone with a large mouth and strong lung capacity to really get all the debris out. 10/10 would recommend.

  2. I didn’t want to believe it, but wouldn’t you know, it worked. 5 colorful slams with my middle and ring finger, followed by a nintendo clearing blow under the space bar…everything’s back to normal.
