My Photoshop install from a previous life is a major reason I still keep a 15-year-old Mac running.

Krita is really nice but it's an artist's tool, not a general image editor. GIMP is a general image editor but… not really nice.

I've debated setting up an offline "creative corner" machine with a comfy older OS and Photoshop, something like Snow Leopard and Photoshop CS1/CS2, precisely because the core of what makes PS useful for me hasn't changed in ages. For my use case the new features added in versions since simply aren't worth the bloat and slowness that's come with them.

There are so many of us with this mindset, if there were usable tools that played well with muscle memory of oldschool adobe workflows the market for new versions of PS in particular and to a lesser extent Illustrator, would fall drastically.

I used to try to port Photoshop to newer OSes etc.

Then I discovered PhotoPea web app online and it’s even better! And available anywhere for free! Have you tried it? Just like Photoshop 5 haha
