Apple System Profiler

Apple System Profiler is a utility that was pre-installed in Macintosh systems from Apple Computer, starting with Mac OS 7.6 in January 1997. As the name suggests, it is an application created to gather detailed information about the Mac on which it is running. This information can be exported and shared with Apple for tech support cases, or with others for alternate forms of troubleshooting.

Mac OS 7.6 to 9.2.2
Apple System Profiler began as a classic Mac OS application program. It could be found directly under the Apple menu and was located inside the Apple Menu Items folder.

Mac OS X
Starting with Mac OS X (10.0.x onwards), Apple System Profiler was moved to the Utilities folder within the Applications folder.

Starting in Mac OS X 10.2, the About This Mac window includes a More Info... button, and the profiler was automatically launched when that button was pressed.

Starting in Mac OS X 10.3, the name of the utility was shortened to System Profiler, with a new user interface.

With the release of Mac OS X 10.7 in 2011, the utility was replaced by System Information.
