Using a Samsung Galaxy S7 (Android 7.0) and a MacBook Air (macOS Sierra 10.12.5), I connect the phone's charging port to the computer's USB port. Neither the phone nor computer bring up any notifications.

I vaguely remember that I used to get a notification when I plugged the phone into the computer, saying they weren't compatible, but I may have opted to stop getting the notification since it happened every time, and I was just plugging it in to charge.

On my Mac I downloaded Android File Transfer, and on my phone I did Settings -> Developer Options -> USB Debugging, but nothing doing. Opening Android File Transfer gives the message "Please connect your Android device with a USB cable to get started.", even when it is indeed plugged in.

Anything I'm forgetting, or ideas for troubleshooting?

(As a note, my goal is to move things from icloud.com to my new android device. For example, I exported a vCard of my Contacts, and I want to move that to my phone to then import into Contacts, etc.)


Some computers only recognize devices when they are plugged into the right usb ports. Have you tried using a different port? Also, some chords can be finicky, some of the cheaper ones don't like you when you try to do get into a device like that.

  • Using a different USB cable worked :)
