To uninstall an incorrect application on an iMac, the standard and recommended method is:
* Identify the application in Finder and drag it to the trash can: This action removes the application from the system. After dragging the application to the trash, the user should empty the trash to complete the uninstallation.
* Move the application to the desktop and press delete: This action does not uninstall the application.
* Use Spotlight to search for the application, and then run the application: Running the application does not uninstall it.
* Use Time Machine to go back to the date before the installation: This method can be used to restore the system to a previous state but is not necessary for uninstalling an application.
