Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

  1. Open Automator.app
  2. Create new Quick Action
  3. Select Run AppleScript
  4. Add this:
set inputVolume to input volume of (get volume settings)
if inputVolume = 0 then
	set inputVolume to 100
	display notification "Volume set to 100" with title "✅ Microphone is on"
