# Homebrew (Mac OS X)
These instructions comes from @Chrisfu, where we got the proxmark3.rb scriptfile from.
For further questions about Mac & Homebrew,  contact @Chrisfu  (https://github.com/chrisfu/)

1. Install homebrew if you haven't yet already done so: http://brew.sh/

2. Tap this repo: `brew tap RfidResearchGroup/proxmark3`

3. Install Proxmark3: `brew install proxmark3` for stable release or `brew install --HEAD proxmark3` for latest non-stable from GitHub.

## Upgrading HomeBrew tap formula

*This method is useful for those looking to run bleeding-edge versions of RRG/iceman's client. Keep this in mind when attempting to update your HomeBrew tap formula as this procedure could easily cause a build to break if an update is unstable on macOS.* 

Tested on macOS Mojave 10.14.4

*Note: This assumes you have already installed RRG/iceman's fork from HomeBrew as mentioned above*

Force HomeBrew to pull the latest source from github

```sh
brew upgrade --fetch-HEAD proxmark3
```

## Flash the BOOTROM & FULLIMAGE

With your Proxmark3 unplugged from your machine, press and hold the button on your Proxmark3 as you plug it into a USB port. Continue to hold the button until after this step is complete and the `proxmark3-flasher` command outputs "Have a nice day!"

```sh
sudo proxmark3-flasher /dev/tty.usbmodemiceman1 -b /usr/local/Cellar/proxmark3/HEAD-<Commit-ID>/share/firmware/bootrom.elf /usr/local/Cellar/proxmark3/HEAD-<Commit-ID>/share/firmware/fullimage.elf
```

> Replace \<Commit-ID\> with the HEAD-XXXX ID displayed by brew.  
> Depending on the firmware version your Proxmark3 can also appear as `/dev/tty.usbmodem881`



## Run the client

```sh
sudo proxmark3 /dev/tty.usbmodemiceman1
```
