System extension cannot be used

The system extension /System/Library/Extensions/hpPluglnlnit.kext was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

System extension cannot be used


Though I’m not using a Mac OS X, it seems that problems with system extensions in Macintosh computers are pretty common and if you are a beginner and it is your first time to use a Mac PC, it will surely give you a headache. Problems with faulty or buggy system extensions in a Mac OS X computer can be due to previous application removal.

If you recently remove or uninstall an application, the said system extension file must have been a leftover of the uninstalled software. Because we all know that when you install a program, most of the time it creates and copies files to different folders in the hard drive and when you decide to uninstall the application, sometimes these files the program created and copied are not entirely removed during the process and that’s when you get file remnant.

In your case, to fix your problem with the buggy system extension, open Finder and navigate to Computer, Macintosh HD, System, Library, Extensions. Find “hpPlugInInit.kext”, select it, and move it to your desktop. Restart your computer and it should work normally again.

Kext files are used for drivers. 

Follow the steps to solve your problem:- 

1) Go to Finder > Computer > Macintosh HD > System > Library > Extensions

2) Find a .kext file with name AppIelnteIE1000e

3) Move this file to the desktop.

It will resolve your problem, because this file might have been stored in your folder, when you have run any driver.
