If a keyboard shortcut doesn’t work on Mac
It’s possible to have keyboard shortcuts for one app that conflict with another app. For example, Command-Space bar opens the Spotlight menu, but in another app it might be used to switch between different input methods.
On your Mac, choose Apple menu
> System Preferences, then click Keyboard.
Click Shortcuts. A yellow warning badge appears next to conflicting keyboard shortcuts. Click the shortcut, then change it. See Use global keyboard shortcuts on Mac.
Thanks for your feedback.
