Without a full user context, Git and its credential helpers +cannot access stored credentials, so some maintenance tasks are not +functional. + +Instead, `git maintenance start` interacts with the `launchctl` tool, +which is the recommended way to schedule timed jobs in macOS. Scheduling +maintenance through `git maintenance (start|stop)` requires some +`launchctl` features available only in macOS 10.11 or later. + +Your user-specific scheduled tasks are stored as XML-formatted `.plist` +files in `~/Library/LaunchAgents/`. You can see the currently-registered +tasks using the following command: + +----------------------------------------------------------------------- +$ ls ~/Library/LaunchAgents/org.git-scm.git* +org.git-scm.git.daily.plist +org.git-scm.git.hourly.plist +org.git-scm.git.weekly.plist +----------------------------------------------------------------------- + +One task is registered for each `--schedule=<frequency>` option. To +inspect how the XML format describes each schedule, open one of these +`.plist` files in an editor and inspect the `<array>` element following +the `<key>StartCalendarInterval</key>` element. + +`git maintenance start` will overwrite these files and register the +tasks again with `launchctl`, so any customizations should be done by +creating your own `.plist` files with distinct names. Similarly, the +`git maintenance stop` command will unregister the tasks with `launchctl` +and delete the `.plist` files. + +To create more advanced customizations to your background tasks, see +launchctl.plist(5) for more information. + + GIT --- Part of the linkgit:git[1] suite |
