macOS Internals

Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.

You've got two main options:

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

	# Script to easily set resource allocation for GPUs to be passed through into a Hyper-V VM
	#
	# Author: ThioJoe / https://github.com/thiojoe

	### Instructions for copying drivers to VM - Will likely need to do this before running this script
	# NOTE: Instead of manually copying the files, if you have an Nvidia GPU you can use my other script called "Copy-GPU-Drivers-VM.ps1" to do it automatically
	# 1. Open C:\Windows\System32 on host machine and copy any files beginning with "nv" (Except nvspinfo.exe and NvAgent.dll , which are unrelated)
	# 2. Place those files into the System32 folder on the VM
	# 3. On the VM, create the following directory: C:\Windows\System32\HostDriverStore\FileRepository
	# 4. For Nvidia GPUs, open C:\Windows\System32\DriverStore\FileRepository, copy any folders beginning with "nv_" (The number of folders should match the number of GPUs, or at least number of different models of GPU)
