Summary: The system folder com.apple.desktoppicture created inside /private/var/folders/**/** grows out of control when changing the wallpaper. Steps to Reproduce: 1. Change systematically the wallpaper using API: [NSWorkspace setDesktopImageURL:forScreen:options:error:] using images not in PNG format and of different resolution than your screen 2. Find your /private/var/folders/**/**/com.apple.desktoppicture Expected Results: 1. Change systematically the wallpaper using API: [NSWorkspace setDesktopImageURL:forScreen:options:error:] using images not in PNG format and of different resolution than your screen 2. Find your /private/var/folders/**/**/com.apple.desktoppicture 3. Folder size should keep constrained using a limited disk space Actual Results: 3. Watch it size grow –the older optimized wallpapers are not deleted. Version: 10.11.3 (15D21) Notes: This can be solved by passing a PNG image that has the same resolution as the screen to [NSWorkspace setDesktopImageURL:forScreen:options:error]. There are users reporting sizes of 7+GB (https://github.com/ifrins/Snappr/issues/3) Configuration:
