Uninstalling applications on your Mac, specifically OS X Yosemite, might seem straightforward, but there are best practices to ensure complete removal and avoid potential system conflicts. This guide provides dependable advice on how to effectively uninstall apps on your Mac running OS X Yosemite. We'll cover various methods, from the simple drag-and-drop to more thorough techniques for stubborn applications.
Understanding App Installation Methods on OS X Yosemite
Before diving into uninstallation, understanding how apps are installed in OS X Yosemite is crucial. Apps can be installed in several ways:
- From the App Store: These apps are usually easier to uninstall as the App Store handles much of the process.
- Downloaded .dmg files: These are disk image files containing the application. Uninstalling these requires more manual steps.
- .pkg installers: These package installers typically place files in various locations. Again, manual removal is often needed.
Method 1: Uninstalling Apps from the App Store (Easiest Method)
This is the simplest method for apps downloaded directly from the Mac App Store.
- Locate the app: Open the Launchpad (typically found in the Dock).
- Find the app you want to remove: Locate the app's icon.
- Uninstall the app: Hold down the app's icon until it starts to wiggle. A small "x" will appear in the corner of the icon. Click the "x" to begin the uninstallation process. Confirm the deletion when prompted.
This method removes the app and its associated files from your system. It's the most straightforward and recommended approach for App Store applications.
Method 2: Manually Uninstalling Apps (For .dmg and .pkg installations)
For apps not downloaded from the App Store, manual removal is necessary. This usually involves several steps:
- Move the App to the Trash: Locate the application in your Applications folder (typically found in your user's home directory) and drag it to the Trash.
- Empty the Trash: Right-click (or Ctrl-click) on the Trash icon in the Dock and select "Empty Trash." This removes the main application file, but not necessarily all associated files.
- Remove Supporting Files (Crucial Step): Many applications create supporting files in various locations, including:
- ~/Library/Application Support: This folder often contains configuration files and other data related to the app.
- ~/Library/Caches: This folder stores temporary files. Removing cached files can help with performance issues.
- ~/Library/Preferences: This folder contains preference files for various applications.
- ~/Library/Preferences/ByHost: This folder might contain app specific preferences.
- Search for Leftover Files: Use Spotlight search (Cmd + Space) to search for any remaining files related to the app. Manually delete any found files. Caution: Only delete files you are absolutely certain are associated with the uninstalled app.
Method 3: Using Third-Party Uninstaller Apps (Optional)
While not strictly necessary, third-party uninstaller applications can automate the process of removing an application and its related files. Several reputable uninstaller tools are available for Mac. Research carefully before choosing one.
Disclaimer: Always back up your important data before uninstalling applications, especially using manual methods. Improper removal of files could cause system instability.
