attn LED 1.0 for Mac
Mac Utilitiesattn LED is a small Mac utility with one focused idea: it turns your MacBook's camera LED into a physical notification light. When an important notification arrives, the LED flashes — and keeps flashing until you actually open the app that sent it, which makes messages much harder to miss while you are focused or have sound off. You choose which apps may trigger the light, so only notifications you care about get the flashing treatment.
Key Features
- Flashes the MacBook camera LED when chosen apps post notifications
- Keeps flashing until you open the notifying app, not just glance at it
- Per-app control with automatic discovery of apps that send notifications
- Works even in Do Not Disturb and Focus modes, according to the developer
- Automatically pauses during FaceTime and phone calls, with a one-click LED test
How to Download
- Make sure you use a MacBook with a camera LED and a supported macOS version.
- Get the app from the developer: Download from the official site
- Install it, grant the accessibility permission it requests, and pick which apps may trigger the LED.
System Requirements
attn LED is a native SwiftUI app that works on macOS 12 or later, and it needs a MacBook with a camera LED — desktop Macs without that LED cannot show the effect. It requires accessibility permission so it can observe notifications as they arrive.
FAQs
Does it record anything with my camera?
According to the developer, the app briefly opens the camera hardware only to switch the LED on and closes it immediately; the point of the app is the light, not video.
Will it flash during calls?
No. The developer states that flashing is automatically disabled during FaceTime and phone calls so the LED does not interfere while the camera is in real use.
