Hey, guys, I recently installed (and quickly uninstalled) Duet Display, but it messed up several things on my MacBook. First of all, various app icons aren't showing, whether they're in the dock, grid, or Finder (screenshot attached). I've Googled similar issues, but they were specific for the dock and involved repairing the disk, which I doubt is necessary. Has anyone experienced this before? Any help would be appreciated.
