How can I tell if I have MediaMax content protection software on my computer?
(top) Windows PCs onto which MediaMax content protection software has been installed will have a file called sbcphid.sys. You can search for this file in Windows by going to Start -> Search or My Computer -> C:\ and entering “sbcphid.sys” as the filename you are looking for. The music on CDs with MediaMax content protection can be played on Macintosh computers without downloading the MediaMax content protection software. If you played one of the CDs on a Macintosh, it therefore is unlikely that you downloaded the software. To be sure, do two things: (a) check the /Library/Startupitems folder for a directory called “sfpatd,” and (b) check the /Library/ApplicationSupport folder for a directory called “M4.” If either directory appears, the software is on your Mac.
