8GB+ USB required.
For post install, all you need to do is open Terminal and enter start. This will run the new script. Choose option 2 for post install.
To use this all you need to do is get your hands on a copy of TransMac and format your USB with the disk image. To do that just follow this,
In the right-side panel of TransMac, right click on your USB Drive >> Format Disk >> Format with Disk Image
There's a TransMac tutorial here.
Install Notes: You may need to hot swap the USB to boot the installer. To do this simply start booting with the installer in a USB 2.0 port and when the USB messages start appearing on the screen swap the installer over to a USB 3.0 port. This is what I had to do and the installer booted up. Also if the installer appears to freeze just reboot and start again but this time while it's installing keep the mouse moving to keep it alive.
Any issues with this please let me know.
