So I have some older Macs I still use from ~2009 and it seems Adobe dropped support for those older CPUs after 2020. Basically I need the installer for Photoshop 2020 v21.x. Thats the last version that will run on my 2009 MacBook Pro. I have the latest creative cloud installed and it does let you pick older versions of Photoshop but the oldest version available that way is v22.2 which doesn't work. Searching online people have said that Adobe support can give you even older installers and I tried that but the oldest they have via direct support is v22.0 which still doesn't work. Seems like the only way to get v21.x is from someone who backed it up when it was still available. I believe it will still work and activate fine with the latest creative cloud app.
