What is ATSServer? Why is it running?

If like me, you keep an eye on the Mac OSX activity monitor, then you’ve likely seen ATSServer and wonder what the heck it is.

ATSServer is the Apple Type Solution Server; responsible for managing the available fonts and making them available to applications.

There are no user configurable setting for ATSServer. It is a harmless process, but needs to be running for your applications to correctly render/display and/or use fonts.
