MacKeeper is not an official Apple product' it's a third-party software utility that offers a variety of tools to improve security and performance of Apple computers. It was originally developed in 2009 by ZeoBIT and as of 2015 belongs to Kromtech Alliance Corporation, who acquired it in April 2013.
MacKeeper consists of 16 different tools that offer security, data control, system cleaning and system optimization. The software also offers a human assistance feature that offers technical support assistance directly from the software suite.
MacKeeper offers three different licenses: a Lite License that offers all the 16 tools for a year, a Standard License that adds System Scan & Fix and live chat to the package, and a Premium License that completes the package with 24/7 call center support, a personal tech expert and priority support.
