Installing MySQL on Mac OS X El Capitan 10.11
Download the latest version of MySQL available from the official web site. At time of writing this was 5.7.9 and the description didn’t say it was for 10.11 – but it works fine. Choose the DMG package for easiest installation. You don’t have to sign up to the web site, just click “No thanks, just start my download” beneath the sign up box.
