Quit Options+ and note your device settings
Before removal, quit the Options+ interface and record any custom button mappings, gestures, or keyboard settings you may want to recreate. Those settings can be stored outside the main app bundle.
Use Logitech's primary removal path
Logitech's basic macOS guidance is to close Options+ and move it from Applications to Trash. If the product is damaged or an older installer supplied an uninstaller, use that vendor-provided path before searching for leftovers.
Review the two Library locations separately
Logitech's complete-removal guidance points to both /Library and ~/Library, including Application Support, Preferences, Caches, LaunchAgents, and LaunchDaemons. Check exact product and vendor identity before removing an item; do not delete unrelated Logitech software you still use.
Look for LogiPluginService only when it matches
Logitech also documents LogiPluginService as a component that may be present in Applications or Utilities. Remove it only if it belongs to the Options or Options+ installation you intend to remove, not merely because its name contains Logi.
Restart and verify macOS settings
Restart the Mac, then review Login Items and Extensions for a clearly named Logitech entry. Confirm that the mouse and keyboard work normally before emptying Trash. CleanWarden can collect ordinary related files into a reviewable plan, but should leave protected extensions and uncertain device services alone.
Frequently Asked Questions
Why is Logi Options+ still listed after I deleted the app?A login item, helper, preference, or related service can remain outside the app bundle.
Should I delete every Logitech file I find?No. Logitech software can support several devices and apps. Remove only files whose product identity is clear.
Can I remove a Logitech system extension blindly?No. Restart first and use the documented vendor path or support if a protected component remains.
