Had the same problem.
More detailed and Windows instructions are here: http://ryancuda.blogspot.com/2013/12/how-to-get-working-adb-drivers-for.html
For my Mac, I was able to connect after doing:
android update adb
- Find your adb_usb.ini file (
locate adb_usb.ini
, mine was in~/.android/adb_usb.ini
) - Get Vendor ID from running
system_profiler SPUSBDataType
. Look for your model or serial number. Mine was "0x2207" for my RCA 7" which showed up as "Fuzhou Rockchip Electronics Co., Ltd." - Add the id to the end of the
adb_usb.ini
fileecho "0x2207" >> ~/.android/adb_usb.ini
adb kill-server
adb devices
- Accept the computer's key on the prompt on your device
