I don't know what made it stopped working. I use BetterTouchTools, but not command has that shortcut and even when I close it, Command + Space still doesn't work.

I checked System Preferences → Keyboard → Shortcuts, and there is no yellow triangle warning, and again Command + Space has no other conflicts. I've restarted my computer and still the problem persists.

I don't know what else to try. Is there any way to check what is being triggered when I press Command + Space key sequence?

I am using a 15" 2017 MacBook Pro running macOS High Sierra 10.13.6.

Edit: This was on a work computer I no longer have access to, so I can't try any solution to see if they work.

same thing happen to my 2 MacBooks, must have been an apple update. in sys pref, it seems the shortcut is still the same.

I pressed the "restore default" button, and it worked again on both laptops

I seemed to run into the same or similar issue—the keyboard shortcut showed up fine in System Preferences and there was no conflict in my BTT configuration—but this did the trick for me:

delete the file home directory/library/preferences/byhost/com.apple.HIToolbox... and log out/in.

rm ~/Library/Preferences/ByHost/com.apple.HIToolbox*
