Spacebar Not Working on Mac (Sequoia/Sonoma)? 5 Quick Fixes

Why Is My Spacebar Not Working on Mac?

The reasons behind a malfunctioning spacebar on a Mac are similar to other key issues, like when the Mac escape key stops working. It’s typically due to a software error, hardware problem, or a mix of both. Because the spacebar is larger and located in the middle of your keyboard, it’s more likely for dirt, food crumbs, and liquids to slip through the gaps around it. Over time, debris can build up under the keycaps, blocking the connection between the spacebar and the circuit board underneath it and making your Mac keyboard spacebar stick.

In some cases, the spacebar not working on your Mac could be caused by software bugs and glitches. This issue is more likely to occur if you are running an outdated version of macOS, if there are unknown bugs in your current system, or if a particular application is interfering with the spacebar's functionality.

Finally, the MacBook spacebar misbehaves due to hardware damage from a heavy drop or worn-out components. Typically, fixing this involves opening up the keyboard, troubleshooting the issue with specialized equipment, and either repairing the keycap or replacing the entire keyboard. We do not recommend attempting this yourself; instead, it's best to take your keyboard to a repair shop.

Mac Space Bar Not Working, How to Fix

Before we begin, clean your keyboard by holding it at a steep angle and using a can of compressed air to spray the problematic spacebar. This can help remove any tiny particles that may be causing the spacebar to stick or malfunction.

Additionally, if you're using a Bluetooth keyboard with your Mac, turn Bluetooth off and then back on, and try reconnecting the keyboard. For a USB-connected keyboard, attempt to plug it into a different USB port on your Mac.

1. Restart Your Mac

If your Mac has been running for a while, cache and background programs might cause your keyboard to act up. The easiest solution is to restart your Mac. This refreshes your system and can fix any temporary issues affecting the spacebar.

2. Reset SMC

The System Management Controller (SMC) on a Mac is responsible for managing various hardware functions, including keyboard operation. As a result, resetting the SMC can sometimes fix keyboard issues such as the Mac spacebar not working.

  • For Intel-based Macs without a T2 chip:
  1. Completely power off your Mac using either the Apple menu or the power button.  
  2. Wait about 10 seconds, then press and hold the Shift + Control + Option keys on the left of your keyboard, along with the power or Touch ID button on MacBook Air/Pro.

  3. Keep holding these keys for 10 seconds, then release them.
  4. Now start up your Mac normally.

For Macs with an Apple Silicon chip, the SMC resets automatically after a restart, so no manual reset is needed. However, some users have reported that holding down the same key combination used for Intel-based Macs can help resolve spacebar issues on M-series Macs as well.

3. Uninstall Conflicting Software

If the spacebar stops working after installing a specific application, uninstalling it may restore functionality. However, simply dragging the software to the Trash won’t fully remove it, as it will leave behind cache files and other leftovers buried in your system.

The most effective way to uninstall an app from your Mac is by using a powerful app remover like BuhoCleaner. Its advanced algorithms can precisely locate all files related to the application and quickly remove any stubborn leftover data from your system.
