How can I uninstall the FTDIUSBSerialDriver and FTDIUSBSerialDriverInstaller from my MacBook Air with Yosemite? They are shown in System Information → Software → Installations.

The files are highlighted in blue below:


First, find out if the package is installed, and it's name:

pkgutil --pkgs | grep -i ftdi

It should output:


Then get a list of files:

pkgutil --files com.FTDI.driver.FTDIUSBSerialDriver

In my case, this was the result:


Then simply delete the files in question:

sudo rm -r /Library/Extensions/FTDIUSBSerialDriver.kext

And follow it up with "forgetting" the package:

sudo pkgutil --forget com.FTDI.driver.FTDIUSBSerialDriver

    This answer still works in 2018. – nomen Jun 22 '18 at 18:33
  • Hm, I'm following these steps but the device still shows up as an interface in the Mac's Network Prefpane. I'm wondering if there's anything additional I need to do to uninstall. Screenshots here: github.com/mavlink/qgroundcontrol/issues/… – Sam Odio Jun 5 at 0:41
  • have you tried simply removing it from the list of networks with the minus button? Does it keep coming back? Does it also exist in the list of interfaces when adding a new interface? Did you try a reboot? (sorry, just had to check)... – zeraien Jun 5 at 10:17

    Shouldn't you be using pkgutil to forget installations? Depending on when the installation was made it might only show up in the database. I've got three related installation packages: com.FTDI.ftdiusbserialdriverinstaller.FTDIUSBSerialDriver-2.pkg, com.FTDI.ftdiusbserialdriverinstaller.postflight.pkg, com.FTDI.ftdiusbserialdriverinstaller.preflight.pkg (pkgutil --packages | grep serial). None of them show up in /Library/Receipts. pkgutil will allow you to 'forget' them, see the man page. Use kextstat to determine if loaded, kextunload to unload if the driver is. – user90735 Jan 11 '15 at 19:36
