How to Install CentOS on a Mac Pro

By Jeff Cunningham

CentOS, or "Community Enterprise Operating System," is a popular distribution of the Red Hat Enterprise Linux platform for Web servers. Supported by donations, the operating system is free and open source software, and the source code is made freely available to the public. It requires no purchase before downloading and installing, and it can also be ordered on a DVD for a fee.
