MacOS – Serious system issue – kernel extensions installed improperly

kernelmacos

I have just gotten an error message for every single kext file there is.
the error message goes something along the lines of:

The system extension "*file path*" was installed improperly and cannot be used. Please try reinstalling it, or contact the products vendor for an update.

If there is something I could do to fix it, let me know.

Sounds like you're going to need to reinstall. Have you done anything different to your system recently (installed new software, had any weird system issues, things like that)? The only thing you might try is running a permissions repair on your startup volume. This will repair permissions for the /Library directory, but it may not resolve the issue since the error states they're not installed correctly. It's worth a try however. You can do this from Disk Utility located in /Applications/Utilities
