High Quality Content by WIKIPEDIA articles! System Profiler is a software utility derived from field service diagnostics produced by Apple`s Service Diagnostic Engineering team, at that time located in Apple satellite buildings in Campbell, California, that has been bundled with the Mac OS since Mac OS 7.6 (until Mac OS X it was called Apple System Profiler). It compiles technical information on all of the installed hardware, devices, drivers, applications, system settings, system software programs and kernel extensions installed on the host computer. It can export this information as plain text, RTF or in the plist XML format. This information is used to diagnose problems. System Profiler can be extremely useful if attempting to diagnose a hardware problem. A user can send the information directly to Apple if the user desires. It has support for scripting automation through AppleScript and some limited support in Automator.
