Instaler for apple tv OSX 11 (el Capitan)

The installer on the site says OSX 10.7 and up.
Tried to run the installer but it requires OSX 12 !

Where to find the OSX 11 version ?
(a USB version preferably)

Or is there a manual / tutorial for a disk image?
And how do I know which one I need?
Any version history?



I think the minimum requirements have changed
You could write the image with dd instead


Hi Sam thanks,

How do write the image to an USB stick?
Only the site still says:


See this steps but be careful as you can break your system

thanks fzinken.

I’ll give it a try tonight…
