How to uninstall DaisyDisk?
Solution 1:
You may want to reinstall it and use "AppCleaner" to properly remove it and all of its remnants.
Solution 2:
If you installed it from the App Store you can delete it from LaunchPad or Finder. Finder moving it to trash works for the direct download version of the app. Spotlight should reveal the location of the app in most cases.
