Downgrade itunes in high sierra So I need to downgrade itunes to 12.0.1 for a jailbreak (6.1.6 on ipod 4g). Currently, you can't just delete itunes. What would I have to do?

My idea is:


Disable SIP (boot into recovery mode and disable)
Delete the Itunes Application
Install the 12.0.1 Itunes


Is it that simple? Anything else I need to remove? I'm trying to get either redsn0w or p0sixspawn to work.
So if you are reading this, this may not be how to downgrade itunes, but this is how I used a different version.


Install VirtualBox
Obtain a .iso version of windows, and Boot it in VirtualBox
download itunes version needed from here within VirtualBox
Do what you need
