The System folder is reserved by macOS
Apple states that Finder cannot delete apps required by the Mac, including many apps installed by macOS and apps in the System folder. A third-party uninstaller should respect the same boundary instead of presenting a disabled button without explanation.
QuickTime Player, Chess, and Stickies are not ordinary leftovers
These Apple apps can appear beside removable third-party apps, but their location and code signature identify them as system software. Their presence after a cleanup is not evidence that the cleanup failed.
Removing a Dock icon does not remove the app
If you only want a cleaner Dock, drag the icon out of the Dock or use Remove from Dock. This changes the shortcut, not the protected app or its documents.
Deleting personal data is a separate decision
Documents, recent-item history, saved preferences, and the built-in app itself are different things. Remove your own files only when you no longer need them. Do not delete broad Apple containers or shared system data just to hide an app.
Do not disable macOS protection for storage savings
Disabling System Integrity Protection or modifying the sealed system volume creates risk for little practical storage gain. If an app is protected, leave it installed and focus on large third-party apps, downloads, installers, caches, and clearly identified leftovers.
What a safe uninstaller should show
A safe uninstaller should label the item as an Apple system app, show its protected location, explain why removal is unavailable, and keep the action locked. CleanWarden treats that information as context rather than a deletion target.
Frequently Asked Questions
Can I delete QuickTime Player from my Mac?On current macOS versions, Finder normally treats QuickTime Player as protected system software. Leave the app installed; remove only your own media files if you no longer need them.
Can I delete Chess or Stickies?They are installed by macOS and may be protected. Their small app bundles are rarely meaningful storage targets.
Why does CleanWarden show a locked app?The locked state explains that the item is visible but protected, system-owned, or not safe to remove through a general cleanup action.
Should I disable SIP to delete a built-in app?No. Weakening system protection to remove a small built-in app is not a reasonable cleanup tradeoff.
