macshome / SKPhyscisBody speed limiter
Created January 9, 2014 17:13
In my asteroids-style game I was looking for a way to limit the speed of the ship so that it didn't get too fast or outrun the missiles it fires. I call this with the update: method on the scene and it just checks the dx and dy values to make sure they are all inside the speed I want to set. In real code I would use a static or value loaded from…
// Speed limiter
- (void)shipSpeedLimit {
// Check the x velocity
if (self.ship.physicsBody.velocity.dx > 500) {
self.ship.physicsBody.velocity = CGVectorMake(500, self.ship.physicsBody.velocity.dy);
} else if (self.ship.physicsBody.velocity.dx < -500) {
self.ship.physicsBody.velocity = CGVectorMake(-500, self.ship.physicsBody.velocity.dy);
}

macshome / StoryboardExtensionsBeta4Fix.swift
Created July 29, 2014 15:26
NSTabView and NSSplitView are busted in beta 4 of Xcode 6 when using OS X Storyboards. If you are using Swift you can drop this file into your project to get them working until there is a fix.
//
// StoryboardExtensionsBeta4Fix.swift
//
// A workaround so that you can use SplitView
// and TabView items in OS X Storyboards on
// 10.10. Just drop this in your Swift project.
//
// Hopefully the need for this goes away in soon
// as it used to work.

How to defang system protections on macOS

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
