I want to downgrade the OS of my Mac Mini which has the sole function of playing media from HIgh Sierra to an older OS. I wonder if anyone can point me to a location to download either an El Cap or SIerra MacOS installer. Many Thanks.
FWIW, if your Mac mini came with High Sierra you can't downgrade to Sierra. If it came with an earlier version you should be able to download Sierra but, you will have to create a USB bootable installer, boot from it, erase your internal drive and install.

You're welcome.
