How can I root my HTC One for T-Mobile using ADB? I want to use ADB. FastBoot isn't working on my OS X machine.

 ./fastboot devices


lists nothing.

 ./adb devices


shows my device

I downloaded SuperSu from the Google Play store but it says it I had to manually root my phone if I am running 4.3 (which I am).

Can anyone please tell me how to use ADB to root my device? ISIS Mobile Wallet app thinks my phone is rooted.
There's a website called HTCOneRoot.com I guess you can find instructions there (videos at the right side, scroll down)
