Android File Transfer Mac “Could not connect to device”

I have installed Android File Transfer on my Mac but, although it recognizes when the phone is connected and auto-starts, I get the error message “Could not connect to device. Try connecting or restarting your device.”

Connecting doesn’t work (it’s already connected but disconnecting and reconnecting doesn’t either) and nor does restarting.

Has anyone got this to work on their S6?

Had the same problem and spent quite a bit of time trying to fix it? While transferring files between your computer and Android device via USB, Android File Transfer is definitely your first choice. It allows you to browse and transfer photos, music and other files between your Mac computer and your Android device with a USB cable.

It seems that you’re not the first person who came across issues Android File Transfer not connecting or recognizing device. Plugged your Galaxy s6 in order to transfer a bunch of files, but encountered the error message as below:

Android File Transfer Cannot Access Device Storage

Can’t access device storage. If your device’s screen is locked, disconnect its USB cable, unlock your screen, and then reconnect the USB cable.

I know it’s frustrating when something should work but doesn’t. Don’t be so upset. Let’s focus on the Android File Transfer not working problem and give you several handful solutions to get the issues fixed.

Troubleshooting Android File Transfer Mac

There are several reasons when you’re having trouble transferring Android files through USB.

  1. USB cable doesn’t support file transfer
  2. Device not set up to accept files via USB
  3. You have Samsung’s Kies file transfer installed
  4. Your micro USB port is broken (sorry, can’t help you with that one)

How to Fix Android File Transfer Mac Issues?

Part 1. Test USB cable and port

  1. Try a different USB cable. Not all USB cables can transfer files.
  2. Test the mini-USB port on your device by connecting your device to a different computer.
  3. Test the USB port on your computer by connecting a camera or other device with USB.

Part 2. Enable file transfer on your Android device

Enable USB file transfer to ensure that transferring files to your Android device is even possible.

To turn on USB debugging mode on your device, go to “Settings” > “Storage” > Tap on the three vertical dots in the top-right corner of your screen > “USB computer connection” > Tick the box next to “Media device (MTP)”.

The solution to the problem on Android Marshmallow 6.0

  2. Back to Settings > Developer Options > Enable USB debugging
  3. Lock device (turn screen off)
  4. Connect your device to computer with a USB cable
  5. Unlock your Android device
  6. Pull down the list of notifications, then tap on “USB for charging”
  7. Bring up the dialog, select “Transfer files (MTP)”
  8. Lock the device and unlock it again

When you do this, the Android File Transfer app will either automatically start (which it does on my Mac), or you can go ahead and start it manually, at which point you’ll see the Android File Transfer main window:

Once you see this window you can go ahead and start dragging files from your Mac (or Windows) computer to this Android File Transfer window.

This method should work on all Android devices running stock Marshmallow 6.0+, like the new Nexus 6P or Nexus 5X.

Part 3. Mac Troubleshooting

  1. Check the version or your Mac OS and Android OS
    You must have Mac OS X 10.5 or later and Android 3.0 or later.
  2. Reboot your Mac computer.
  3. Make sure that the Android File Transfer application is open.

Part 4. Android Troubleshooting

  1. Update your Android version to the latest version available.
  2. Reboot your Android device.

Part 5. Uninstall Samsung’s Kies file transfer software (skip if not installed)

The issue might be caused by the program Samsung’s Kies, which most of us have installed on our Mac from when we first plugged our phones in, messes with AFT.

  1. To uninstall Kies, download SAMSUNG KIES from Samsung’s website and run the dmg.
  2. Then select Uninstall and wait.
  3. Rebooted after uninstall

uninstall Samsung Kies Mac

Then reconnect your Android device and you should be set. Couldn’t believe it but so glad that Android File Transfer is working again. Good luck!
