“Will dragging the OnyX App icon from the Applications folder to the Trash remove it entirely along with all associated files?” That’s a thread in the Apple Communities.
OnyX for Mac is a free multifunction utility for maintenance and optimization. To delete this app from your Mac can be quite easy, but erasing all its components from the system is totally not the same thing. If OnyX fails to perform the way you expect, make sure to take proper steps to achieve thorough OnyX uninstall on your Mac.
Here we will discuss the answers to 4 questions to help you have a comprehensive understanding about how to effectively uninstall OnyX and remove app leftovers.
Being prompted that “OnyX cannot be moved to Trash because it is in use”? Here’s the fix: before uninstalling any app on Mac, remember to shut down all its running processes. So, if the OnyX is active, quit this app, and if necessary, launch Activity Monitor to check if there is any associated process running on the background.
The macOS provides multiple options to quit a running or frozen app:
(1)Right click on the app icon on the Dock, and choose the Quit option
(2)Click the app icon in the Menu Bar, and choose Quit [app name]
(3)Launch Activity Monitor, select the process pertaining to the target app, then click the X button on the upper left corner, and click (Force) Quit in the pop-up dialog.
What if the target app cannot be shut down even in Activity Monitor? To solve this issue, you can reboot your Mac into Safe Mode, and then perform the uninstall.
After shutting down OnyX, you can uninstall this app by trashing it in Finder. Here are the regular steps to uninstall OnyX (or other 3rd party apps )on macOS/Mac OS X:
Note: Be cautious when trying to empty the Trash. Deleting OnyX individually in the Trash avoid the risk of mistakenly deleting other files that may still be needed.
>> For some apps that come with a dedicated uninstaller, you can locate the uninstaller in the folder that contains the app, and launch the tool to start the removal.
Some versions of OnyX come with a dedicated uninstall script/option. You can head to the Help menu on the top bar when OnyX is active, and check if the Uninstall OnyX option is available in the sub-menu. If it exists, you can perform the OnyX uninstall by choosing the option and following the prompts to finish the process.
If the Uninstall option is not in the menu, you can double click to open up the Onyx installation file, and see if the Uninstall icon can be found in the package.
>> For apps that are installed through Mac App Store, you can head to the Launchpad, press and hold the app icon until it starts to jiggle, and then click the Delete button.
The aforementioned uninstall ways cannot guarantee you a 100% removal of all Onyx items. To achieve satisfactory result, you may still need to manually remove Onyx remnants from deep system directories. Follow the steps below to handle this task:
Here are the directories that may contain OnyX components:
~/Library/Caches, ~/Library/Preferences, ~/Library/Application Support, ~/Library/Saved Application State, ~/Library/LaunchAgents, ~/Library/LaunchDaemons, ~/Library/PreferencePanes, ~/Library/StartupItems
It is notable that, some items created by OnyX may not contain the title of the app or its vendor, and that means you may still fail to track down all the components. If you are still upset by this uninstall issue, consider to use the one-stop solution below.
