Is there an SVG version of the Finder icon from macOS Big Sur?
Solution 1:
I decided to just trace over the macOS Big Sur Finder icon in Inkscape, and it turned out pretty great.
It's simplified compared to the PNG that Apple provides, there's no shadows around the icon and no shading on the eyes and mouth, but that might not be noticeable anyway at small scales. I compressed the SVG file using the svgcleaner tool, it's 1,729 bytes.
