The pointer crosses onto the display beside your game.
For League players on Mac with two screens
Your cursor just left the match. Again.
You pan to the edge. Your mouse slips onto the MacBook screen. The camera stops—and sometimes the whole game loses focus. Display Lock turns off the spare display in macOS until the match is over.

Try the toggle. This is what the Mac app changes.
If this sounds familiar
Yes. It’s that Mac bug.
League loses focus, the camera stops, or your FPS drops.
Until it behaves—then it happens again next fight.
The workaround without the ritual
Stop rearranging your entire Mac just to queue.
Players have been moving displays into tiny corners, mirroring screens, playing at smaller resolutions, and repeatedly switching out of the game. Display Lock gives the practical fix its own button.
BEFORE DISPLAY LOCK
- Drag the monitor arrangement into a weird corner
- Switch to a smaller window and avoid the edges
- Mirror the MacBook display or close the lid
- Cmd-Tab out and back when focus breaks
WITH DISPLAY LOCK
1Turn off the spare screenmacOS removes that desktop entirely.
2Play the matchThe edge is a real edge again.
3Turn it back onYour normal setup returns after GG.
Not a cursor cage
It removes the second desktop.
Blackening a monitor is not enough—your pointer can still disappear into the invisible desktop. Display Lock asks macOS to disconnect that display from the active layout, then restores it when you are done.
⌃⌥⌘W
Always have a way back
The last active display can’t be turned off. The global shortcut wakes every detected display.
Pick the screen you’re playing on
Keep the external gaming monitor or the MacBook display—your call.
Flip the other display off
Windows come home and your cursor has nowhere else to go.
Bring everything back after the match
One click restores the display, including a screen that is currently off.

Straight answers
Before you install.
Is this specifically for League of Legends?
That dual-monitor Mac issue is why it exists. Display Lock does not modify League, though the same display toggle may help other games with escaping cursors.
Does it just make the other screen black?
No. The spare display is removed from the active macOS desktop, so your cursor and windows cannot move into it.
Can I turn off every screen by accident?
No. Display Lock refuses to disable the last active display, and Control–Option–Command–W restores every detected screen.
Is the beta Apple-notarized?
Not yet. This early build is locally signed, so macOS may ask you to confirm it in Privacy & Security before opening it.
