Completely Remove Apps: The Smart Uninstaller Guide

The Problem with Dragging to Trash

When you drag an app to the Trash, you're only removing part of it. Applications leave behind:

• Preference files in ~/Library/Preferences
• Application support in ~/Library/Application Support
• Caches in ~/Library/Caches
• Saved states in ~/Library/Saved Application State
• Containers in ~/Library/Containers
• Login items and launch agents

These leftovers can consume gigabytes of storage over time.

How Much Space is Wasted?

Common apps and their typical leftover sizes:

• Adobe Creative Cloud - 2-10 GB
• Microsoft Office - 1-3 GB
• Xcode - 5-50 GB (with caches)
• Games - 500 MB - 5 GB each
• Development tools - 1-10 GB each

Safe Uninstallation

Review Before Removing

Always check the file list before uninstalling:

• Verify you selected the right app
• Check for shared files with other apps
• Note any preferences you might want to back up

Apps to Be Careful With

Some apps share components:

• Adobe apps share common files
• Microsoft Office apps share frameworks
• Apple's built-in apps shouldn't be removed

After Uninstalling

Verify Removal

After uninstalling:

1. Check Applications folder - app should be gone

2. Search Spotlight for the app name

3. Run a Quick Scan to catch any missed files

Restart if Needed

Some apps require a restart to fully remove:

• Apps with system extensions
• Apps with login items
• Apps that modify system settings

Reinstalling Later

If you need an app back:

• Download from the original source
• Preferences will be fresh (clean start)
• No conflicts with old files
