Troubleshooting: List installed 3rd-party kernel extensions

TerminalBack in the days prior to OS X, it was easy to find 3rd party (and Apple) system extensions on your Mac. They were all located in the System>Extensions folder. With OS X though, the task of even knowing which kernel extensions are installed isn’t quite as easy, which can be particularly frustrating when you’re troubleshooting an issue on your Mac.

For the geeks among you, it’s quite easy though. To list all 3rd party extensions, simply launch the Terminal app located in your Utilities folder and type the following:
kextstat | grep -v com.apple

You can also list all the Apple-installed kernel extensions by typing:
kextstat

I came across this little hint over at OSXDaily, a site I visit quite often because of the variety of topics covered.
