can't connect to Android File Transfer on Mac

[rayancaleb]

Hi,

I have installed Android File Transfer on my MacBook Air but I keep getting 'If your device's screen is locked, disconnect its USB cable, unlock your screen, and then reconnect the USB cable' whenever I connect the KEYone to my computer. There must be something I need to do first on my phone but I can't figure out what...Can somebody help?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
