Figured out how to apply any arbitrary SF Symbol to a folder in Tahoe.

xattr -w 'com.apple.icon.folder#S' '{"sym":"camera.viewfinder"}' some/folder/here

It also works with private symbol names!

also because emoji labels are just handled as strings, you can put anything in the emoji config thing.

While I was sharing your hack, someone showed me how to go open info on a folder, then drag a svg onto the info wondow, and it becomes the default image for that folder....

Then I played around a little, and found that I could add, throuth edit and insert on the title field in the info dialog, and I can add an emoji rught there..... So, thanks!

@samhenrigold this seems far too complicated than it ought to be. then again, in windows you need icons in a ICO or DLL (or EXE, or anything else that can hold icons in that format really) to use them as custom icons for folders or shortcuts

Furbland's Very Cool Mastodon™, in macOS you could also set a custom .icns for a folder or a disk since about forever

@samhenrigold Technically this also requires setting the folder as having a custom icon, which the xattr alone is not enough.

@mikeymikey maybe try this mdls flag? that’s the only other metadata i observed that changes when you set an icon

@samhenrigold Custom icon is a Carbon-era filesystem flag. GetFileInfo and SetFile (if you have developer tools installed) will let you toggle it on a stock macOS install directly if you don't go the route of pasting in a custom icon / using APIs to configure a file's icon

I would not be surprised it maps to FinderInfo since that's the name of the struct member
