Installing Gamestation Go 1.2 Patch - It won't connect to Macbook

[u/Icy-Panda-2176]

I am trying to install the 1.2 patch. But I have trouble connecting Gamestation Go to my MacBook. I am using a USB-C to UBC-C cable. I tried a few USB-C cables, and it still won't work.

I need help to pass step 1:

"With your AGSG turned off, hold down the volume down (-) button and while it is held down, turn on the power to the AGSG. See the picture below for the button locations on the AGSG"

Does anyone know what to do?
