System Information For Mac
System Information (formerly System Profiler) in OS X provides a detailed breakdown of the hardware and software configuration of a Mac, from Bluetooth information and attached USB devices to installed software and extensions. While most of us have used System Information at one time or another, it’s an often overlooked and undervalued tool. To get the most out of it, we’ll exploring the app, and its lesser-known command-line options, in further detail. Launching System Information There are a number of ways you can access System Information as it has a number of shortcuts in different places, the most common way is from the About This Mac pane. Click on More Info to reveal some additional information about the Mac and then click System Report You can bypass this process completely by holding down the Alt key when in the Apple menu. This will swap About This Mac to System Information and allow you to launch it directly. Finally, you can simply launch the app from where it resides: within /Applications/Utilities.

In 1984, Apple debuted the operating system that is now known as the 'Classic' Mac OS with.
The System Information App The System Information app is nothing more than a tweaked XML viewer. It doesn’t do anything itself, instead relying upon the system_profiler command (which we’ll come to later) to generate hardware and software configuration reports. The report that the command generates is then opened by System Information and formatted in a way that’s easy to view. System Information also views a report that has already been created, though it can be refreshed at any time by selecting File > Refresh Information. Each section is broken down into its respective categories, such as Hardware, Network and Software, and their related reports are separated into subcategories.
Within the app’s menu are a few options that can alter the output of the report. If you’d prefer not to view a full report, you can select Show Less Information which will hide most Software reports. This can be toggled by selecting Show More Information to bring them back.
System Reports A great benefit of System Information is that reports can be saved and opened on any Mac. You can save a report from one Mac and open it on another, useful when trying to troubleshoot an issue with a remote Mac.
