What do you mean by decoded? This is all my original work, I had this sitting for a while and decided to make an app to make it easy. I found out today there is a tutorial for the system version check and I found out while trying to upload the app here.
In addition my patches activate couple of more perks.
Also look for two more apps I am uploading how to get it to run during the El Capitan Installer.
So basically if your question is whether I copied someone and I have to give them credit, no I didn't.
