Table of Contents


Tumult is an oh-my-zsh-compatible plugin that adds macOS-specific functions and scripts to your ZSH environment.

Some of these are mine, and have an Apache 2.0 license, some of them were written by other people and just colllected by me - the authors and licenses are embedded in those scripts.

Tumult will check to see if you're running on macOS and not add aliases or inject its bin into your $PATH if you aren't. This was done to enable you to use the same plugin list in all your environments without polluting your $PATH with incompatible functions and scripts on your non-Apple machines.

You may also find the git-extra-commands collection useful, or my zsh-quickstart-kit


The Tumult collection is Apache 2.0 licensed. Some scripts in the bin directory have different licenses - if so, they have those other license statements embedded inline in their source.

Included scripts

Script Description

kick-afp Restart file sharing from the CLI. I got tired of having to remote desktop in to kick the fileserver via the GUI every time Apple's file sharing got wedged, now it can be fixed over ssh
kick-screensharing Sometimes screen sharing just hangs on my Mini running 10.11. This is not new to 10.11, it was exhibiting the same annoying behavior on 10.10 and 10.9. The mini is headless and it's a pain in the ass to plug it into the TV just long enough to restart screen sharing, so I wrote this so I can fix it over an ssh connection.
kill-screensaver Kill the screensaver when it locks up
kill-sophos-dead From a slack, but won't name names lest their employer find out they kill sophos. Kill Sophos' useless scanner when it gobbles up all your CPU. People wouldn't hate antivirus software so much on macOS if it restricted itself to using one CPU core.

set-mojave-disk-warning-threshold Mojave now pops up a warning when you're running low on disk space. Unfortunately the threshold they pick triggers a warning every couple of minutes on my MacBook Air. This script lets you set a different number of free gigabytes to warn at.
