Out of the box the tada68 uses a .bin firmware file instead of a .hex like other custom keyboards. By default QMK will build and copy the correct .bin file for you. If for some reason you need a hex file instead, you can add `:hex` to your make command, or look inside `qmk_firmware/.build` to find the hex file.
*When flashing the keyboard from a Mac, you must delete some files that are automatically created by the operating system in order to prevent bricking your keyboard.

1) from the `qmk_firmware\` directory run:
```
$ make tada68:default:flashbin
```
2) Connect your keyboard to your Mac, hit the reset button on the bottom of the TADA, the lights will start flashing.
3) You'll see a new drive on your computer called TADA68. Backup the original factory `FLASH.BIN` file that's inside it.
4) Open the terminal and cd to the folder where the keyboard has been mounted
`cd /Volumes/TADA68\ /`
5) Copy over your new firmware to the keyboard
`cp -r <path to your qmk_firmware folder>/FLASH.bin .`
6) Remove files that MacOS automatically created which interfere with the keyboard
