Since this guide is specifically for the Proxmark3 Easy, we will use either the stable or non-stable release for generic (non-RDV4) devices. The GitHub documentation was a little confusing on this part, but the releases come in stable and non-stable versions for three different categories: the standard release (for RDV4 devices), the standard release (for RDV4 devices) with BlueShark Bluetooth module support, and the generic release for non-RDV4 versions of the Proxmark3. There are multiple releases, so choose the one that best fits what you are looking for. Tapping a repository (a reference to tapping a keg) allows you to access third-party repositories that aren’t included in Homebrew’s master repository. Now tap RFID Research Group’s Proxmark3 repo: If you don’t already have the Homebrew package manager installed, you’ll need to do that now: If you get a related error in the future, just re-install them with the same command above. It’s important to note that sometimes macOS updates will mess with the Xcode Command-line Tools. You can do this by running the following command: The first thing you will need to do is install the Xcode Command-line Tools package if you don’t have it installed already. These steps follow instructions from as documented on RFID Research Group’s Proxmark3 GitHub repository. If you need to manually install Rosetta 2, you can do that by running the following command: Rosetta 2 ships with macOS Big Sur, and the first time you go to run an Intel-based application you should get a prompt to configure Rosetta if necessary. If you are using a Mac with an Apple Silicon M1 chip, you need to make sure you have Rosetta 2 installed and working. Rosetta is the translation layer that allows Intel-based applications to run on the M1 chip’s ARM architecture.

However, while the Dangerous Things guide is for using a Windows host (with a link to RFID Research Group’s macOS instructions partway through) and the GitHub documentation covers instructions for the various versions of the Proxmark3, this guide is written specifically for using the Proxmark3 Easy with a macOS host. This guide will follow Dangerous Things’ getting started forum post and instructions from various GitHub READMEs. You can find the Proxmark3 Easy from Dangerous Things here. The Proxmark3 is an RFID diagnostic, testing, and programming tool, and this pre-loaded version makes for an easy way to get straight into RFID research without having to install firmware and bootloaders yourself like you would need to do with the standard Proxmark3 that comes with no software pre-installed.

This is a getting started/set up guide for the Proxmark3 Easy from Dangerous Things that comes pre-loaded with the Iceman firmware. Getting Started with the Proxmark3 Easy (macOS) – Poetsec
