Removing a Mac's Firmware Password By Reflashing EFI ROM

According to Apple, the only way to remove an unknown firmware password from a MacBook (2011 and later) is to take it to the Apple Store with the original proof-of-purchase. However, I've found that there is another way, which I've been successful with for the unibody MacBook Pro--it's essentially just modifying a couple bytes in the EFI ROM, which should be simple. What's not simple, however, is figuring out how to read and write to the EFI chip. In this post, I'll talk about the process that I figured out and what worked for me.

The Official Method

Apple's method of resetting the firmware password is not reproducible, as Apple generates an SCBO file that unlocks the EFI using their private key. You can read more about this process here. The problem with this system is that, if you are in the unfortunate situation of neither having the firmware unlock pass

Works for macOS Sierra and High Sierra

Taken from 2011 Macbook Pro Graphics Card FIX 100% WORKING!!!

EDIT This method works! But there is an improved version for better thermal management and brightness keys functionality. See improved version -> https://gist.github.com/cdleon/d1eff7246a25193304284ecec40445b0

Enter Recovery Mode (text mode)

if you are on high sierra 10.13.6+ you might need to use Command + r instead

Boot up holding down Command + r + s

Known Issues: On High Sierra there are problems related to the screen brightness and sleep issues.

1. Reset SMC and NVRAM

NVRAM: https://support.apple.com/en-us/HT204063

2. Change the gpu-power-prefs and disable SIP

GenStage Tutorial

Introduction

So what is GenStage? From the official documentation, it is a "specification and computational flow for Elixir", but what does that mean to us?
There is a lot to something that can be described as that vague, and here we'll take a dive in and build something on top of it to understand its goals. We could go into the technical and theoretical implications of this, but instead lets try a pragmatic approach to really just get it to work.

First, Let's imagine we have a server that constantly emits numbers. It starts at the state of the number we give it, then counts up in one from there onward. This is what we would call our producer.

#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault
