macOS Internals

Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.

You've got two main options:

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus

	# Place me in ~/.config/fish/functions
	# Then add me to `fish_vcs_prompt`: `funced fish_vcs_prompt` and save it to
	# your personal config: `funcsave fish_vcs_prompt;`

	function fish_jj_prompt --description 'Write out the jj prompt'
	# Is jj installed?
	if not command -sq jj
	return 1
	end

	#!/bin/sh

	# Called by "git push" after it has checked the remote status,
	# but before anything has been pushed.
	#
	# If this script exits with a non-zero status nothing will be pushed.
	#
	# Steps to install, from the root directory of your repo...
	# 1. Copy the file into your repo at `.git/hooks/pre-push`
	# 2. Set executable permissions, run `chmod +x .git/hooks/pre-push`
