🚀 Ultimate Guide: How to Permanently Delete Microsoft Edge WebView2 on Mac (Step-by-Step Removal)

Is Microsoft Edge WebView2 cluttering your Mac, slowing things down, or just taking up precious space? You're not alone! Many Mac users encounter remnants of this Windows-centric runtime when developing cross-platform apps, using Electron-based tools, or installing Microsoft software bundles. While Microsoft Edge WebView2 is primarily designed for Windows, stray files or dependencies can linger on macOS via development kits, npm packages, or Edge browser caches.

This comprehensive, no-nonsense guide walks you through how to permanently delete Microsoft Edge WebView2 on Mac. Follow these proven steps for a spotless uninstall—your Mac will thank you with lightning speed and freed storage. Let's dive in! ✅

What is Microsoft Edge WebView2 and Why Remove It from Mac?

Microsoft Edge WebView2 is a control that lets developers embed web content into native apps using Edge's Chromium engine. On Windows, it's a standalone runtime; on Mac, it rarely installs natively but appears in developer environments like VS Code extensions, Electron apps, or Homebrew formulas tied to Microsoft tools.

• 👉 Reasons to delete: Bloats storage, causes compatibility glitches, privacy concerns from telemetry, or conflicts with Safari/WebKit apps.
• ⭐ Frees up 500MB+ space instantly.
• 😊 Restores smooth performance—no more random crashes!

Prerequisites Before Uninstalling

Backup your Mac with Time Machine. Close all Microsoft apps (Edge, Teams, Office). You'll need admin privileges. Pro tip: Download a free tool like AppCleaner for easier residue hunting, but we'll cover manual methods too.

Step-by-Step: How to Permanently Delete Microsoft Edge WebView2 on Mac

We'll use a hybrid approach: official uninstall + manual cleanup. This ensures permanent deletion—no ghosts left behind!

1. 1️⃣ Uninstall Microsoft Edge Browser (Primary Source)
   Open Finder → Applications → Drag Microsoft Edge.app to Trash. Empty Trash. If Edge isn't there, skip to step 2.
2. 2️⃣ Remove WebView2 Runtime via Terminal (Key Step)
   Open Terminal (Spotlight: Cmd + Space, type "Terminal"). Run these commands one by one:
   

   sudo rm -rf /Library/WebView2
   sudo rm -rf ~/Library/Application\ Support/Microsoft/EdgeWebView
   sudo rm -rf /usr/local/lib/libWebView2.dylib

   Enter your password when prompted. These target common WebView2 paths on Mac dev installs.
3. 3️⃣ Clear Caches and Preferences
   In Finder, press Cmd + Shift + G. Delete these folders:
   
   • ~/Library/Caches/com.microsoft.edge.WebView2
   • ~/Library/Preferences/com.microsoft.WebView2.plist
   • ~/Library/Saved Application State/com.microsoft.edge.WebView2.savedState
   Pro tip: Use rm -rf ~/Library/Caches/*microsoft* in Terminal for speed.
4. 4️⃣ Purge Homebrew or npm Installs
   If installed via package managers:
   brew uninstall --ignore-dependencies microsoft-edge-webview2
   Or for npm: npm uninstall @microsoft/edge-webview2 (in project dirs).
5. 5️⃣ Restart and Verify
   Reboot your Mac. Open Activity Monitor → Search "WebView2" → Force quit any processes. Use Spotlight to search—no results? You're done! 🎉

• ❌ Edge Reinstalls Itself? Disable auto-updates in Edge settings first.
• 💡 Stuck? Check for Electron apps (e.g., VS Code) embedding WebView—update them.
