Prevent macOS from locking the screen when connected to a specific Wi-Fi network.

Story

I want my MacBook to stay awake while I'm at home, but still sleep and lock normally anywhere else.

anti-locker prevents idle sleep only when the Mac is connected to a Wi-Fi network I have explicitly allowed. On any other network (or when Wi-Fi is off) it does nothing. Manual screen lock (Ctrl+Cmd+Q) and display-off always work.

Technologies

anti-locker is built with:

• Go.
• macOS caffeinate to block idle sleep.

How it works

1. Every interval seconds, check the current Wi-Fi SSID.
2. If the SSID matches a configured network, run caffeinate -i to block idle sleep.
3. If the SSID stops matching (or Wi-Fi drops), stop caffeinate.

Installation

git clone https://github.com/ansidev/anti-locker.git
cd anti-locker
go build -o anti-locker .

Usage

anti-locker                                # use ~/.config/anti-locker.yaml
anti-locker --config /path/to/config.yaml  # custom config path

Configuration example:

interval: 3600 # seconds, defaults to 3600
networks:
  - "Home Network 1"
  - "Home Network 2"
