Mac driver for OPT

Hello guys, I just unlocked bootloader and try to flash twrp on my brand new OPT. The problem is that osx doesn't recognize the device (./adb devices find nothing).
So when I try to flash recovery it does it, but it doesn't work at the same time.

Any idea to solve this? Where I can find drivers for mac?

Thanks!

edit: I managed to let the device recognized, but even if I flash twrp, I have the stock recovery.
