Unable to use unsigned third driver after resolving Mac 10.11

Resolves the latest version of the MAC system cannot use unsigned third-drive 10.12. Multiple

My case is that 10.11.4 Beta (15e27e) uses a green-linked USB adapter that is not normal.

The following command is for some commands to detect whether the driver is loaded.
sudo kextload/library/extensions/ax88772.kext

Error:

Failed to load-(libkern/kext) not found; Check the System/kernel logs for errors or try Kextutil (8).

sudo kextutil-v ax88772.kext
CODESIGN-DVVV Ax88772.kext
Codesign--VERIFY-VVVV Ax88772.kext

It's easy to say, but the new features of Mac
System Integrity Protection shut down.
Closing method:
1. Restart the computer, hold Command and R during startup;
2. After entering the recovery interface, open the terminal in the tool;
3. Enter Csrutil status to view the current status;
$ csrutil Status
System Integrity Protection status:enabled.
4. Input: Csrutil disable close SIP
5. Restart your computer

After restarting if you can go to the network settings to check if there is a NIC in effect, if not effective can be executed:
sudo kextutil-v ax88772.kext

This is the end!
