Got my new RPi 3s. So exciting! Connect to my [serial cable](https://www.adafruit.com/products/954https://www.adafruit.com/products/954), fire up [Serial](https://itunes.apple.com/us/app/serial/id877615577?mt=12) on the Mac, ready to install my normal way, and….garbled garbage.
Turns out some winner in Piland re-used GPIO pins necessary to make serial work for Bluetooth. I guess they figured that no one used serial console?
To fix, you’ll need a monitor & keyboard. First follow the instructions [here](https://medium.com/where-the-flamingcow-roams/raspbian-setup-notes-677a71de5b9f#.xm7jhawwi) up through “Update firmware” (rpi-update). Then edit /boot/config.txt and add the line:
dtoverlay=pi3-disable-bt
Reboot, and your serial console will work again.
