MySQL

MySQL is again a missing component in OS X 10.9 and needs to be dowloaded from the MySQL site use the Mac OS X ver. 10.7 (x86, 64-bit), DMG Archive version (works fine on 10.9).

When downloading you don’t have to sign up, look for No thanks, just take me to the downloads! - go straight to the download mirrors and download the software from a mirror which is closest to you.

Once downloaded install the 3 components.

You may need to adjust the Security and Privacy System Pref to allow installs of 3rd party apps because of the new security feature of Mountain Lion known as the Gatekeeper, which keeps unscrupulous installer packages at bay.

To get around this without changing the global preferences (better!) right click or command click the .pkg installer to bring up the contextual menu and select open, then you get the warning - then click Open.
