I'm talking about the System 7/8/9 days of macOS. I really like the aesthetic and workflow in the older macOS versions (call me a masochist) and I'm hoping if someone knows of something that already exists. I know there are plenty of skins/themes that hearken back to Windows 95/98, but most of what you find online when you look for "Linux like macOS 9" is things that make it look like modern macOS.
