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

This Gist provides examples of providing global IPv6 addresses inside OpenVPN tunnel.

If you have /48 subnet which is most likely routed prefix, see https://community.openvpn.net/openvpn/wiki/IPv6 If you have /64 subnet which is most likely link prefix, see openvpn-link64-v6-over-v4.md file If you have some other configuration (i.e. just /124 -- digitalocean, i'm looking at you), or just want to use weirdest config ever, see openvpn-nat6.md (which is yet to be created)

All configurations I've tested work great on Windows, Linux, iOS and Android. For macOS, either use Viscosity (paid), or see Tunnelblick/Tunnelblick#452 for Tunnelblick.

Combining two git repositories

Use case: You have repository A with remote location rA, and repository B (which may or may not have remote location rB). You want to do one of two things:

preserve all commits of both repositories, but replace everything from A with the contents of B, and use rA as your remote location
actually combine the two repositories, as if they are two branches that you want to merge, using rA as the remote location

NB: Check out git subtree/git submodule and this Stack Overflow question before going through the steps below. This gist is just a record of how I solved this problem on my own one day.

Before starting, make sure your local and remote repositories are up-to-date with all changes you need. The following steps use the general idea of changing the remote origin and renaming the local master branch of one of the repos in order to combine the two master branches.
