Open Settings → Appearance to change supported diCleaner visual preferences.
Choose an appearance
Use a mode compatible with your macOS light or dark environment and accessibility needs. Test result lists, confirmation sheets, and secondary text for readability.
Apply and verify
Some windows update immediately; others may need to be reopened. Change one preference at a time.
Restore default
Use the supported default control or return to the system-following option. Restart diCleaner if an old window keeps its previous appearance.
Display problems
Update macOS and diCleaner, restore default appearance, and test without unusual contrast or color filters. Include a redacted screenshot and display configuration when contacting support.
Appearance settings do not change scan rules or file selections.
