I've used my Go with my 2015 MacBook. Worked okayish. Windows doesn't require any special software to do this, but Mac does. You need the Android transfer utility from https://www.android.com/filetransfer/ installed on your Mac. The cable that came with your Go should work fine for this task.
I have Android Studio installed, after I put Go to developer mode, I can use "adb devices" to list Go ... and using "Android File Transfer" i can exchange files between my Mac and Go.
It seems that first oculus go has some known problem to connect to PC. I guess Mac too. wangwjun, I turn on enable adb device and go is in developer mode, but i can't find the way to list devices in studio... I'm not a developper just upload it to mount my go...
Same here, the Go was recognised a few times, copying went troublesome, losing connection in the process. Now the Go is no longer found when connected. Tried different cables, other Macs newer Android File Transfer but nothing seems to get it connected.
