Launch ssh-agent on boot (OSX macos)

AddSSHKeysAtLogin.plist

<plist version="1.0">
	<dict>
		<key>Label</key>
		<string>ssh-add-a</string>
		<key>ProgramArguments</key>
		<array>
			<string>/usr/bin/ssh-add</string>
			<string>-A</string>
		</array>

</plist>

install.sh

#!/usr/bin/env bash

# Usage:
#   curl -sSL https://gist.github.com/RichardBronosky/429a8fff2687a16959294bcee336dd2a/raw/install.sh | bash
# or:
#   wget -qO- https://gist.github.com/RichardBronosky/429a8fff2687a16959294bcee336dd2a/raw/install.sh | bash


dest="$HOME/Library/LaunchAgents/"
url="https://gist.github.com/RichardBronosky/429a8fff2687a16959294bcee336dd2a/raw/AddSSHKeysAtLogin.plist"

mkdir -p "$dest"
cd "$dest"
curl -sLO "$url"

This is a great example of a login service!

A different approach solved my ssh-agent issues. I added global IdentityFile entries to ~/.ssh/config for each of my keys.

IdentityFile ~/.ssh/git_rsa
IdentityFile ~/.ssh/id_rsa 

Problem solved!

GitHub has also updated their documentation to include similar advice, but I found it necessary.
