Apple's Mac OS X Lion Installer link warning.
I'm trying to download Mac OS X Lion to have the last version 10.7.5 to install on an old Mac. I'm using Apple's page here: Mac OS X Lion Installer
When I click on it, I get the warning, "This connection is not private." The link is pointing here: https://updates.cdn-apple.com/2021/macos/041-7683-20210614-E610947E-C7CE-46EB-8860-D26D71F0D3EA/InstallMacOSX.dmg
I thought https://updates.cdn-apple.com was officially Apple and safe. Since I can no longer download Lion from the AppStore, is this the only way to get this installer or is there another option? Is this link just old and getting that warning, or should it really be avoided?
Thanks!
