= macOS Service (launchd)
This option installs OliveTin as a launchd service, so it runs in the background and starts automatically. This is the macOS equivalent of running OliveTin as a Linux systemd service or a xref:install/windows_service.adoc[Windows service]. If you just want to run OliveTin as a regular application, follow the xref:install/macos.adoc[macOS Desktop install] instructions instead.
Before continuing, complete the xref:install/macos.adoc[macOS Desktop install] steps (download, extract, and clear the Gatekeeper quarantine) and confirm OliveTin starts correctly by running `./OliveTin`.
== Choose LaunchAgent or LaunchDaemon
launchd offers two ways to run a background service, and which one you pick decides whether you need root:
* *LaunchAgent (local user)* - runs as your user and starts when you log in. *No `sudo` required*, and everything lives under your home folder. Best for a desktop Mac. Follow <<local-user,Local user installation>>.
* *LaunchDaemon (system-wide)* - runs as `root` and starts at boot, before any user logs in. Requires `sudo`. Best for a headless, always-on Mac. Follow <<system-wide,System-wide installation>>.
You only need to follow *one* of the two sections below.
[#local-user]
== Local user installation (no root)
Everything - the binary, configuration, the `var` data folder, and the `webui` folder - is kept together under `~/Library/Application Support/OliveTin`, so you never need `sudo`.
=== Install the files
Run these from the extracted archive directory:
[source,shell]
----
# Create the application folder and a place for logs
mkdir -p ~/Library/Application\ Support/OliveTin/var
mkdir -p ~/Library/Logs/OliveTin
# Copy in the binary, your config, and the bundled web UI
cp OliveTin ~/Library/Application\ Support/OliveTin/
cp config.yaml ~/Library/Application\ Support/OliveTin/
cp -R webui ~/Library/Application\ Support/OliveTin/
----
This gives you the following layout, all owned by your user:
[source]
----
~/Library/Application Support/OliveTin/
├── OliveTin # the binary
├── config.yaml # your configuration
├── webui/ # the web interface assets (shipped in the archive)
└── var/ # runtime data OliveTin writes (logs, etc.)
~/Library/Logs/OliveTin/olivetin.log # service stdout/stderr
----
=== Create the service definition
Create a file named `app.olivetin.olivetin.plist` with the contents below.
[IMPORTANT]
launchd does *not* expand `~`, so the paths must be absolute. Replace `YOUR_USERNAME` with the output of `whoami` in every path.
[source,xml]
----
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>app.olivetin.olivetin</string>
<key>ProgramArguments</key>
<array>
<string>/Users/YOUR_USERNAME/Library/Application Support/OliveTin/OliveTin</string>

</dict>
</plist>
----
`WorkingDirectory` makes the relative `webui` and `var` folders resolve inside the application folder, `KeepAlive` restarts OliveTin if it exits (like systemd's `Restart=always`), and `RunAtLoad` starts it as soon as the service is loaded.
=== Register and start the service
[source,shell]
----
cp app.olivetin.olivetin.plist ~/Library/LaunchAgents/
launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/app.olivetin.olivetin.plist
----
[NOTE]
`bootstrap`/`bootout` replace the deprecated `launchctl load`/`unload`. They take a _domain target_: `gui/$(id -u)` is your own per-user GUI domain (`id -u` is your numeric user ID).
To stop and disable it:
[source,shell]
----
launchctl bootout gui/$(id -u) ~/Library/LaunchAgents/app.olivetin.olivetin.plist
----
=== Restart after a change
After editing `config.yaml` or replacing the binary, restart the service so the change takes effect. To restart in place:
[source,shell]
----
launchctl kickstart -k gui/$(id -u)/app.olivetin.olivetin
----
If you changed the *plist* itself, `kickstart` is not enough - boot the service out and back in so launchd re-reads it (`bootstrap` errors if the service is still loaded):
[source,shell]
----
launchctl bootout gui/$(id -u) ~/Library/LaunchAgents/app.olivetin.olivetin.plist
launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/app.olivetin.olivetin.plist
----
=== Verify
Open http://localhost:1337 in a browser. If the page does not load, check the service log:
[source,shell]
----
tail -f ~/Library/Logs/OliveTin/olivetin.log
----
[#system-wide]
== System-wide installation (requires root)
Use this for a headless or shared Mac that should start OliveTin at boot, before anyone logs in. It installs the binary on the system `PATH` and runs as `root` via a LaunchDaemon, so the commands use `sudo`.
=== Install the files
[source,shell]
----
sudo cp OliveTin /usr/local/bin/OliveTin
sudo mkdir -p /usr/local/etc/OliveTin
sudo cp config.yaml /usr/local/etc/OliveTin/config.yaml
sudo cp -R webui /usr/local/etc/OliveTin/
----
[NOTE]
OliveTin looks for `config.yaml` in the directory given by the `-configdir` flag, which defaults to the current directory. The service definition below passes `-configdir /usr/local/etc/OliveTin` explicitly, and sets `WorkingDirectory` so the `webui` and `var` folders resolve there.
=== Create the service definition
Create a file named `app.olivetin.olivetin.plist` with the following contents. Adjust the paths if you installed OliveTin elsewhere.
[source,xml]
----
<?xml version="1.0" encoding="UTF-8"?>

`KeepAlive` restarts OliveTin if it exits (like systemd's `Restart=always`), and `RunAtLoad` starts it as soon as the service is loaded.
=== Register and start the service
[source,shell]

----
[NOTE]
`bootstrap`/`bootout` replace the deprecated `launchctl load`/`unload`. The domain target for a LaunchDaemon is `system`.
To stop and disable it:
[source,shell]
----
sudo launchctl bootout system /Library/LaunchDaemons/app.olivetin.olivetin.plist
----
=== Restart after a change
After editing `config.yaml` or replacing the binary, restart the service so the change takes effect. To restart in place:
[source,shell]
