A working .dmg i can download NOT from apples website, that i can use to burn onto a usb stick, to install on a Macbook. I cant find one that works anywhere online and i dont have a Mac to make a bootable dmg.
MacBook Pro 13″, OS X 10.11
macOS versions 10.12 and older are downloaded as .dmg which holds a .pkg that creates the actual installer to /Applications. You can then create a bootable installer from that via a Terminal command. A catch is that you need a Mac that supports that macOS version to do all that fluently although using a VM might be a workaround. Anyway, I'd avoid downloading OS from shady sources.

El Capitan is still available for download directly from Apple.

I clicked on the El Capitan link a ways down the page and it does download an OS X installer, despite the fact it cannot in any way be installed or run on an M4 Pro mini.
Edit: Whoops! Matti Haveri already supplied this link.
i now find out the reasons the dmg files that i was using to try and install macos were broken, using a new one let it install.
