I used to be able to download old versions of the OS from the dev program's download section, though admittedly it's been a while.
I need a copy of High Sierra to resurrect an old MacPro we use for testing. When I try to do it from my iMac (running a newer OS) it tells me I can't get that upgrade (because of course I don't need it for that machine, I need it for another).
And before anyone points me to https://support.apple.com/en-eg/HT211683 -- the links on that page take you to the App Store, so not helpful.
Is there any place to get old OS installers anymore?
