Why don't you want to download from Apple? That's the only official place to
get macOS.
10.6 and earlier were never on the App Store; they're on DVD.
10.9 was the first free version. Before that the OS cost money.
If you ever downloaded 10.7, 10.8, or 10.9 on the App Store you should still be
able to get it that way; check your Purchased tab.
For 10.10 and newer, use the download links in this article:
