If you use my Folderol app, you may encounter issues in Mojave. I have not but I can confirm that some of my users have found that their folders tend to be “sticky”, and will keep their icons and folder colors even when they’ve been changed to new ones.
If this happens to you, the easiest solution is to set up a new folder, customize it with Folderol, and transfer the contents and rename it like the old one. I have reports of the issue with 10.14.3 and 10.14.2. The most common factor among those affected is that the system is running one or more UI customizations like dark mode.
Folderol works by using Apple’s
NSWorkspace method that sets an icon for a file. So the actual “work” beyond creating and blending the icon is done by that class, over which I have no control.
I’m going to try to update the app description with a warning about the problem and add a set/remove/set sequence to see if that helps.
If you’re experiencing issues with Folderol, please let me know your OS specifics, and whether you’re using custom dark mode and/or tints. Thanks!
