How to disable the CTRL+SPACE default shortcut on macOS

- by

Unreal Engine likes to use CTRL+SPACE to bring up the content browser. I’ve never had a Mac powerful enough to run UE5 until recently, and imagine my surprise when that shortcut swapped my keyboard layout from UK to German instead of showing my assets. Turns out macOS has this enabled by default, and I needed to disable it.

Here’s how to do it:

  • head over to System Settings – Keyboard
  • click on Keyboard Shortcuts – Input Sources
  • disable the top option called “select the previous input source”

The UE Asset Browser works a treat now.
