Events & Delegates
------------------

Events and Delegates were something I struggled with when I was first learning how they worked. Once I figured it out it became one of the most useful and powerful techniques for games. Its especially useful for helping to decouple classes while allowing for messaging. 

Delegates - Simply a container for a function that can be used as a variable. 

Events - Allows you to specify a delegate that gets called when some event in your code is triggered.

To summarise the above:

1. Very important, go to System Preferences -> Security. Click on the Privacy tab and choose Full Disk Access. Click 🔒 at the lower left hand corner to unlock. Then √ the Terminal.app.
2. In Finder, choose from the menu Go -> Go to folder, then paste the following line: ~/Library/Application Support/MobileSync
3. You should then see a folder called Backup. Copy this folder to the external hard disk.
4. Optional: Create a folder called Backup somewhere else on your external harddisk.
5. Open Terminal app then type: sudo -s When asked, type your Mac login password.
