I was using a Nexus 7 and after I upgraded it to the latest Android 6.0, suddenly I couldn’t connect my tablet to my Mac to transfer files.
The following error appeared each time I plug in the USB cable:
Can’t access device storage
If your device’s screen is locked, disconnect the USB cable, unlock your screen, and then reconnect the USB cable.
Of course, I tried the suggested solution but it didn’t help. Trying another USB cable and plug to another computer didn’t work either, so I think this might be the issue of the mini-USB port. Fortunately, it wasn’t. Here is how I fixed the issue.
- Connect the Android device to my Mac
- Pull down the notification bar, you will see a message saying “USB for charging“, tap on the line to reveal more options
- Choose MTP
- Open Android File Transfer to start transferring your data now.
If you followed the steps and your device still fails to connect to your computer, you might need to contact the manufacturer for warranty or repair service.
