You could install a Virtual Machine on your new Mac with the appropriate version of macOS and Adobe Photoshop. Just another answer to add to the list of options. However, Adobe gives no other option really. I understand that none of these options are really that great it's something I've struggled with too, personally. There's some info floating around about it, but nothing is really guarenteed to work.Īs it stands, your options are basically as follows: Though CS3 does support Intel Macs without Rosetta, and in theory, the binaries should launch on modern versions of macOS, compatibility with newer versions is.
This means that, at least on a new machine, partitioning and installing an older version on bare metal is out of the question.
Macs very rarely support booting versions of macOS older than the one they shipped with-exceptions are few and far between, and never more than a year's release.
