Bootable installer for "any" MAC OS

Updated 2023-06-11 !

The use case is that I had an old iMac, max OS is High Sierra, that crashed and it didn't work with an Internet or Time Machine restore.

The other MAC:s I have are running Catalina or Big Sur and if you try to download and older OS, via app-store, you just get an error saying that the running OS don't accept the download of an old OS.

The universal way to create an USB installer seems to be using the command "createinstallmedia", requires OS X 10.7 Lion or later, but you need the respective OS install app !

A new, better ??, without Python dependences is found here.

macOS Ventura on unsupported Mac

In former posts, Big Sur(11.7) and Monterey(12.7), I went through how to update an old MacBook Air 4.2, (mid 2011, SSD, 4 Gb memory) which has a Non-Metal GPU.

In this post I will update a MacBook Air 6.2 with SSD, Mid 2013, to Ventura(13.5) with the same patcher but the latest version 6.2 !! 

This is despite that max OS for this Mac is Big Sur

Awesome !!!

Supported models are found here.
