I recently got an Elgato Stream Deck for the home office, and I’ve set it up mostly to control OBS Studio for a couple of projects I’m working on. Since I also have a couple of Key Light Airs, I also use it to control them.
While setting it up, I figured I needed a sleep button on it, that basically locks my Macbook and turns off the lights in one fell swoop. Conceptually this seemed like an very easy thing to set up, but it turns out there are some macOS quirks that needs to be addressed for this to work.
By default in macOS High Sierra, or newer, there is a predefined lock screen hotkey:
Command ⌘ + Control ⌃ Q which works very well. In fact, it works a little to well as it turns out. The problem was, that when I tried to enter
Command ⌘ + Control ⌃ Q as the hotkey combination in my button settings in the Stream Deck configuration, the screen locked. Naturally. And Stream Deck never recorded the hotkey, since it automatically locked the MacBook.
Luckily, there was a somewhat convoluted but at the same time pretty easy fix for this.
Creating a Lock/Sleep button for Stream Deck #
Assign a temporary lock hotkey
You will first need to temporarily assign a new hotkey for the lock screen, in order to ensure that macOS doesn’t lock the screen when hitting the original hotkey to record it in Stream Deck.
To do this navigate to System Preferences -> Keyboard -> App Shortcuts.
Counterintuitively select to add a new hotkey by clicking the + sign
Under Menu Title, enter Lock Screen This is important, as it needs to match the existing menu item.
Then under Keyboard Shortcut, enter a new key combination that you can assign temporarily.
In this example I used
Command ⌘ + Control ⌃ L, but it can be anything. Then click on add
Create a Multi Action button in Stream Deck
Add a System -> Hotkey to the Multi Action button, and assign it the
Command ⌘ + Control ⌃ Qhotkey.
This time macOS won’t lock up, since the the hotkey for locking as been temporarily changed to whatever you chose in step 1.
In my case, I also added a Stream Deck -> Control Center: On / Off button as well, as I wanted to make sure my Key Lights got turned off at the same time. Close the Stream Deck app.
Go back to System Preferences -> Keyboard -> App Shortcuts and delete the temporary Lock Screen definition, to restore the original
Command ⌘ + Control ⌃ Qhotkey to macOS and profit! Now your new Stream Deck Sleep/Lock button should work, in addition to the original macOS hotkey assignment.
A bit counter intuitive at first glance, but it makes sense that the hotkey for locking the screen needs to be disabled to be able to record it into the Stream Deck App.
