About System Information

System Information is an app included with OS X. It tells you which Mac model you have, the version of OS X you’re using, what devices you have connected, and more. In some versions of OS X this app is referred to as "System Profiler".

Open the System Information or System Profiler app from the Utilities folder of your Applications folder. Or just hold down the Option key while choosing System Information or System Profiler from the Apple menu.

When you open this app, a system report appears. This report contains detailed information about your Mac.

To view the different kinds of information stored in this report, click the items in the left pane of the System Information window. For example:

• Hardware gives you an overview of the model of Mac you are using, its processor speed, and how much memory is installed.
• Software shows you which version of OS X you are using, and which startup (boot) disk your computer is currently using. 
• Memory tells you how much total RAM you have installed in each of your Mac's internal memory slots.
• Network shows you which networking features, like Ethernet and Wi-Fi, are available on your Mac. It also tells you what your current IP address is for each connection.
• USB shows you how many USB ports you have on your mac, their speeds, and what devices are connected to these ports. Some of the connections listed may be internal for items built into your Mac. For example, the FaceTime HD camera on a Mac portable is connected to an internal USB connection on the computer's logic board.
• FireWire tells you how many FireWire ports you have available on your computer, and which devices are connected to your FireWire ports.
• Thunderbolt lists how many Thunderbolt devices you have and what devices are connected to each Thunderbolt port. This includes Thunderbolt ports on connected Thunderbolt displays.
• SATA shows you drives that are connected to your mac using a Serial ATA connection. These drives are normally connected internally to your computer's logic board.
