System Info For Mac

System Info is a free and easy to use Mac OS X application that makes it simple to get detailed information about your system's kernel extensions and hardware devices.

After you start the System Info tool, it will automatically start scanning for all the devices available on your Mac and, using the data from Michal Vaner's and Martin Mares' PCI ID Project, it will build a comprehensive list of devices and kernel extensions available on your system.

On the Devices tab, the System Info app displays a full list of all active devices, together with their vendor and device IDs, for easily finding compatible kernel extensions if needed.

System Info's Kexts tab lists all the loaded kernel extensions and, with the help of a simple icon-based system, if they work and are compatible with your Mac.

You can also check if all the devices installed on your system are compatible, with the help of the "Check compatibility" feature, easily accessible via System Info's File menu.

Another worth mentioning feature is the fact that System Info also makes it possible to effortlessly export your list of devices and kernel extensions for further troubleshooting on help forums.
