## Command Line Instructions
|
|||
|
|
|
|||
|
|
OS X comes with `Python 2.7` installed, but not `pip`. The following uses Homebrew to install `python3` which includes `pip3`. On MacOS you will use `pip3` instead of `pip`.
|
|||
|
|
|
|||
|
|
:::note
|
|||
|
|
Check if you have Homebrew installed with the following command
|
|||
|
|
```bash
|
|||
|
|
brew -v
|
|||
|
|
```
|
|||
|
|
If it's not installed, follow the instructions on the [Homebrew website](https://brew.sh) before continuing.

1. Install Python3
|
|||
|
|
```bash
|
|||
|
|
brew install python3
|
|||
|
|
```
|
|||
|
|
2. Confirm `pip3` was installed alongside `python3`
|
|||
|
|
```bash
|
|||
|
|
pip3 -v
|
|||
|
|
```
|
|||
|
|
3. Install `esptool`
|
|||
|
|
```bash
|
|||
|
|
pip3 install --upgrade esptool
|
|||
|
|
```
|
|||

|
|
5. Confirm that your device is talking to your Mac by running the following command in Terminal.
|
|||
|
|
```bash title="Command"
|
|||
|
|
esptool.py chip_id
|
|||
|

|
|
```bash title="Expected Output"

7. Install the correct firmware for your board with
|
|||
|
|
:::caution
|
|||
|
|
Be very careful to install the correct load for your board. In particular the popular 'T-BEAM' radio from TTGO is not called 'TTGO-Lora' (that is a different board). So don't install the 'TTGO-Lora' build on a TBEAM, it won't work correctly.
