Building the USB Installer

Once you have your 8+GB USB installer, we need to make sure it's set up properly. If you don't plan on patching the installer (and I don't) - you want the USB setup the following way:

  • GUID Partition Map

  • 1 Partition

  • OS X Extended (Journaled)

To do this, fire up the Terminal (located in /Applications/Utilities) and type diskutil list.

This will give you a list of all the connected disks and their partitions. Take note of the disk identifier for your USB drive. DO NOT GUESS THIS AS WE ARE ABOUT TO ERASE IT! Then run the following replacing disk# with your actual identifier:

diskutil partitionDisk /dev/disk# GPT JHFS+ "USB" 100%

This will partition the disk as listed above and rename it to "USB".

You can now run the corresponding command from Apple's own instructions - for this example, we'll be using the Mojave command:

sudo "/Applications/Install macOS" --volume /Volumes/USB

This will take some time, and it doesn't output much for status updates. It can take upwards of 30-40 minutes, so just be patient. Grab a cup of coffee, read the news, catch up with friends and family - you'll be here for a bit

When this completes, you will have a USB installer that can boot on a real Mac. We just need to get the Hackintosh-related stuff set up, and we'll be in business!

For those that are timid around the command line - I did put together a script awhile back that can perform these actions for you.
