Hey folks! I'm trying to reset my old iMac, but I hit a snag at the service center and now it specifically needs macOS High Sierra (version 10.13) to be reinstalled. The issue is that Apple stopped offering the official download link for High Sierra, and the service center mentioned that I need a Mac running High Sierra to create the installer myself.
I'm on the lookout for either a reliable source to download the 'Install macOS High Sierra.app' or a .dmg/.pkg file. If anyone can point me towards a safe link, or guide me on how to make a USB installer if I can get a hold of the installer file, I would really appreciate it! Thanks a ton! 🙏

Why are you stuck on High Sierra? You might be able to use Sierra instead. Here’s a link to that version below if it helps!
You can actually find the download link for macOS High Sierra on Apple's support site. Check this out: https://support.apple.com/en-us/102662. Just a heads up, though, you’ll need a compatible Mac to download it from there.
Thanks for the link! I understand that Apple provides it, but I **don’t have a Mac.** It seems like I can only get High Sierra on a compatible Mac, so I'm still searching for a way to get that installer file directly.

I appreciate the suggestion! The reason I need High Sierra (10.13) specifically is that my iMac's firmware and setup require that version to properly reinstall the OS. Sierra (10.12) just won't cut it for this machine.
