Setting Desktop not working in High Sierra

[rconradharris]

I'm noticing that that the osascript command to set the Desktop is exiting with 0, but not actually setting the desktop background.

This could be yet another High Sierra bug, or maybe they intentionally broke compatibility here. Either way, the only workaround I can think of is, is to warn the user and recommend that they point the System background selector to the ~/Reddit Backgrounds directory
