How to Tell If You Have USB 2.0 Ports on an iMac


Apple's iMac, a desktop computer with an integrated processor, hard drive and flat-panel display, is currently available in models with 21.5-inch and 27-inch displays, as of early 2011. The latest iMacs come with one FireWire 800 port, an SDXC card slot and four USB 2.0 ports. You can plug a variety of devices into a USB port, such as a printer, scanner, MIDI keyboard, digital camera, an iPod or an iPhone. If you are uncertain about whether your iMac model has USB 2.0 ports, which allow for faster data transfer than USB 1.0 ports, you can easily find out with the free Apple System Profiler utility that is installed on every iMac.

  • Click on the Apple logo from the top left of the menu on your iMac, and then click "About this Mac." A window will appear showing what operating system version is running on the iMac.

  • Click the "More Info" button on the "About This Mac" window to access the Mac System Profiler.

  • Click on "USB" under the "Hardware" section in the left pane of the System Profiler window. Look at the details about the iMac's USB ports under the "USB Device Tree" in the top pane of the System Profiler window. It will say "USB 2.0" if you have USB ports.

  • Click "System Profiler" from the menu, and then click "Quit System Profiler" to exit.
