Back in the Windows world there was a Device Manager control panel that would list all the devices that were connected to your computer.

There was even an option to show "hidden devices", basically a list of items like thumb-drives, SD cards, etc. that were once connected to your PC.

I'm just curious if something like this exists in OSX? Is there a list of devices that are connected or ever were connected?


Search for System Information in Lion or later (or System Profiler in Snow Leopard and earlier versions of Mac OS) in Spotlight (press and Space).

The program is in /Applications/Utilities and is the tool to see the connected USB devices and other hardware details. It is quite simliar to Device Manager on Windows.

Alternatively you can access it via the Apple Menu

-> About This Mac -> More Info... -> System Report...

System Information

The System Information can save system profiler information to a file, so you could review an older snapshot to see what was connected once, but the Mac OS doesn't record all the devices connected - just the ones actually connected when you run the tool and it scans the current items on the device tree.

    +1, BUT: System Profiler does NOT offer you any option to change device settings.

    Still wondering if is possible to manage (not only list, like the System Information do) my USB devices, like turning off the trackpad USB.

    Use Command+R to refresh the list of connected devices
