How to Defang macOS System Protections

If you want to change things on the root drive of a Mac you will need to take some steps to disable the built in security of the system. Most of these steps are the same regardless if you are on Intel or Apple Silicon. If there is a difference it is noted.

Note that all of these things put a Mac into an unsupported and less secure state.

Make sure you either perform these steps in a VM or that you reset the protections after you are done poking around

Protections and Terms

(This list is not exahustive on the details of each. Check the links at the end for more info.)

Objective-C implementations in Swift

Proposal: SE-NNNN
Authors: Becca Royal-Gordon
Review Manager: TBD
Status: Awaiting implementation (but only of resilience support)
Implementation: In main and release/6.0, behind the ObjCImplementation experimental feature flag
Upcoming Feature Flag: ObjCImplementation

Introduction

GPG signing –

Here is a short guide that will help you setup your environment to create signed commits or signed tags with Git locally. This has been extensively tested on Windows with Git and the Github Desktop application: I use it every day for my professional development projects.

I you face any issue, feel free to leave a comment below.

How to use

1. boot in recovery (command+r)

You can temporarily disable SIP by rebooting into Recovery Mode (press and hold Command-R from the time the computer starts until you see the Apple logo), then opening Terminal from the Utilities menu and entering this command:

csrutil disable

2. boot in normal:

UPDATED 22.11.2022

It's been two years since the last update, so here's the updated working script as per the comments below.

Thanks to BryanHaley for this.

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

 video.querySelector('#primary button[aria-label="Action menu"]').click();

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

	// Run code in Browser Console after enabling chrome debugging --
	// about:config => devtools.chrome.enabled => true
	// https://developer.mozilla.org/docs/Tools/Browser_Console
	try {
	var tabPromise = SyncedTabs._internal.getTabClients();
	tabPromise.then((arrDevices) => {
	if (arrDevices && arrDevices.length > 0){
	// Generate a string with the format of a bookmark export file
	var d, e, out = '<!DOCTYPE NETSCAPE-Bookmark-file-1>\n<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=UTF-8">\n<TITLE>Bookmarks</TITLE>\n<H1>Bookmarks Menu</H1>\n<DL><p>\n';

	Reverse Engineering the Apple Airscan / eSCL Protocol

	I am not certain of the origins, one person involved in IPP printing claimed it was proprietary of HP , but then again they have their own protocol. AirScan/eSCL is used by other manufacturers too like Xerox, Kyocera, Canon and more. Mopria also seems to claim some responsibility for it but then again it seems not completely. In any case it seems shrouded in such secrecy that to date several years after its implementation, unless someone wants to take it all apart.

	I offer this as my contribution. It is not perfect but almost there.

	As I began looking for information to make a scanner more compatible, I could only find fragments of information. Even Apple Developer Forums offered zero help.

	Server/Client in eSCL / AirScan:
	There is a “server”and a “client” the client can be a desktop computer or mobile device. The server is a scanner or another device configured to emulate a hardware scanner, even a desktop computer. In my case I did this on Linux, so

	'use strict'

	import { app, BrowserWindow } from 'electron'

	/**
	* Set `__static` path to static files in production
	* https://simulatedgreg.gitbooks.io/electron-vue/content/en/using-static-assets.html
	*/
	if (process.env.NODE_ENV !== 'development') {
	global.__static = require('path').join(__dirname, '/static').replace(/\\/g, '\\\\')
