... Here are direct links I’ve compiled for easy access:

     macOS Sonoma
     macOS Ventura
     macOS Monterey
     macOS Mojave
     macOS Catalina
     macOS Big Sur
     macOS High Sierra

For even older macOS versions, visit Apple’s website, where they keep an 
archive of these files. Look for a DMG file; after you download it, 
you’ll find the PKG file inside the disk image. These versions are also 
a bit tricky to find, so I’ve also made it easy for you. Simply click on 
any of the links to start your download.

     macOS Lion
     macOS Mountain Lion
     macOS Yosemite
     macOS El Capitan
     macOS Sierra
