I have a mac mini with MySQL installed. The database is owned by my account (yeah, that is dumb, I know now... and if the machine is ever rebooted either to install updates or maybe the machine loses power, I have to manually launch mySQL using launchctl. I've tried adding entries to /Library/LaunchAgents based on the example provided by homebrew, but it always seems to fail. I did add in the key/value pair for UserName, but that doesn't seem to work. Any suggestions what I have done wrong?
