Hi, running Big Sur on Macbook Air and trying to copy a kext to the system extensions folder. I have SIP disabled, I am logged as an administrator but I still cannot access the systems extensions folder. When I try to change the permissions of the folder, I get a msg saying I don't have the necessary permissions...but I'm the admin. I downloaded and ran three KEXT loaders, each say they ran succesfully, but the kext does not appear in the folder and it is not loaded. I suspect it is a folder permission issue, but I can't seem to get it solved. Help?
