How to Fix Double Space Keyboard Issue on Mac

Multiple Apple users have encountered problems with the space bar on their Mac. It has been reported that pressing the space bar once ends up typing two spaces. This is due to malfunctioning space keys, for both Mac notebook and desktop keyboards. You can use these tips for other keys repeating as well.

Why does this happen?

The double space issue could be caused by improper setting of the space bar on the keyboard. However, this is much less likely than a hardware issue, like your space bar being sticky. Sticky keys are easily fixed. This article will explain how to troubleshoot the double space issue on Macs.


  1. Check for a Setting Issue

First, check to see if the problem is being caused by an inadequate key setting. If your key was installed improperly or has become faulty, this can be causing the problem. Start by going into your keyboard settings.

To access your Mac’s keyboard settings, go to the Apple Menu > System Preferences > Keyboard. Toggle the “Key Repeat” and “Delay Until Repeat” settings and see what happens.

  • Key Repeat – Press and hold any key on your Mac until it begins repeating. Determine how fast you want the key to react when it is held down. If you do not want a character to repeat itself at all when a key is held down, you can turn the repeat setting off. Play around with typing and see what your space bar does.
  • Delay Until Repeat – You are able to adjust the delay period before a key begins repeating after being pressed down. Adjust this setting to your liking and see if it makes any changes.


  1. Clean Your Keyboard

If you think it is a hardware issue, make sure your keyboard and keys are clean. Look carefully under the keys. Check your space bar for any debris, dust, or any other small objects that could be obstructing it. If you notice tiny objects stuck under your keys, follow these cleaning procedures:

  • Power off your Mac.
  • Hold your laptop or keyboard upside down.
  • Carefully tap on the bottom and try to shake the objects loose.
  • If you have a keyboard vacuum handy, now is the time to use it.
  • You can also use compressed air to blow any dust and debris out from under the keys.


That Didn’t Work. What Do I Do?

If you weren’t successful with any of the previous steps, it may be time to consider contacting Apple Support. You can visit their support website here. Check their FAQs and forums for any helpful advice on the issue. You can also enter a live chat with a customer service representative here.


If you believe the issue is being caused by a hardware problem, schedule a Genius Bar appointment. They will be able to determine the issue and make recommendations for repairs if you need them.


AppleCare Warranty

If your Mac is still under Apple’s warranty, they will pay for the repair. If you don’t know your Mac’s warranty status, visit their warranty page here. If you are not covered, you will likely need to replace your keyboard. This can be very expensive, so make sure you aren’t still under warranty.


In conclusion, repeating keys can be very annoying. The fix can be very easy, but can also be very expensive. Try to determine if the issue is with the key setting, or if your keyboard just needs a good cleaning. Don’t hesitate to contact Apple if you cannot fix the issue yourself.
