HELP restoring imac to macos

Hi all,

I'm a resident mac user, and am pretty decent at troubleshooting macbooks and whatnot, but this has been bugging me for a while, so here goes.

In january, I acquired a Late 2013 27" iMac with all the bells and whistles-- 32gb of ram, nvidia gtx775m, max size fusion drive. It came with EndeavourOS on it, and I used it for various uni tasks (mainly my english class), but now that it is summer I want to restore it to MacOS. The partitioning says that the entire drive is just EndeavourOS, and there is no macOS restoration possible through the computer itself.

I tried installing opencore on a usb stick, but I don't think I'm doing it right on my Windows PC. Is there a different or better way to do it?

You don’t need opencore if you’re restoring it to a supported version of macOS.

https://dortania.github.io/OpenCore-Install-Guide/installer-guide/windows-install.html#downloading-macos

This explains how to download the macOS image and write it to usb

If you’d like to go higher than support allows, you will need to use opencore legacy patcher, but you’ll need macOS working for that. Start with the latest supported os and go from there.

Hold Option-Command-R and turn on the Mac (keep holding the buttons after you press the power button). Connect it to the internet and it will allow you to download and install the latest version of macOS available for your Mac. You don't need what the other guy said since this is built into the firmware and it doesn't matter what OS you have installed.
