@Pedro_Neto Yes, I've also disabled the SIP but couldn’t manage to install it properly. I don't know why. My Mac just won't let this program work for some reason. Can you let me know what you EXACTLY...

@Creator1111 I followed all steps and it didn’t work. :(

@Creator1111 Hi, I installed the driver, but it's still not recognizing the device (Archer T9UH V2). Would it be possible for you to help me understand why it's not working properly?
