#### macOS
First, you need a Ubuntu/Debian Linux (virtual) machine to convert the `.elf` file from into a `.bin` file that the `dfu-util` understands. Copy the latest `.elf` for your board from [here](https://github.com/madcowswe/ODrive/releases). Proceed to convert the binary (tested on Ubuntu 18.04):
First, you need to install the arm development tools to copy the binary into the appropriate format.
```text
$ brew cask install gcc-arm-embedded
```
Then convert the binary to .bin format
```text
$ sudo apt install binutils-arm-none-eabi
$ arm-none-eabi-objcopy -O binary ODriveFirmware_v3.5-48V.elf ODriveFirmware_v3.5-48V.bin
```
Back on the macOS machine (tested on macOS High Sierra), install `dfu-util`:
Install `dfu-util`:
```text
$ sudo port install dfu-util # via MacPorts; for HomeBrew use "brew install dfu-util"
```
Then, copy the new `.bin` firmware file to the macOS machine, find the correct device serial number to use.
Find the correct device serial number to use:
```text
$ dfu-util --list # list the DFU capable devices
