How to Move Apps on MacBook to an External Drive (and Free Up Space on a 250GB Hard Drive) -

Running out of space on your 250GB MacBook? Moving apps to an external drive can help you clear up room for essential files and system functions. Here’s a step-by-step guide to safely relocate applications and keep them accessible.

⚠️ Important Notes Before You Begin:

Not all apps can be moved — some require being on the internal drive.
Performance may suffer — apps may load more slowly depending on the external drive’s speed.
Use a fast external SSD (USB 3.0 or Thunderbolt recommended).
Always back up your Mac before making major changes.

✅ Steps to Move Apps to an External Drive

1. Format the External Drive Properly

Open Disk Utility.
Select the drive, click Erase.
Format as Mac OS Extended (Journaled) or APFS.
Name it something recognizable like ExternalApps.

2. Create a Dedicated Applications Folder

On the external drive, create a folder named Applications.

3. Move the App

Go to your internal Applications folder.
Drag and drop the app you want to move to the Applications folder on the external drive.
Enter your admin password when prompted.

4. Create a Symbolic Link (Symlink)

This allows macOS to think the app is still on the internal drive.

Open Terminal and type:

bash

CopyEdit

sudo ln -s /Volumes/ExternalApps/YourAppName.app /Applications/YourAppName.app

Replace YourAppName and ExternalApps with your actual app name and drive name.

5. Test the App

Launch the app from the Launchpad or Spotlight.
If it works, you’re good.
If not, try reinstalling it directly to the external drive.

❌ Apps That Should Not Be Moved

System apps (Safari, Mail, etc.)
App Store apps (some may break or auto-reinstall internally)
Adobe Creative Cloud or similar apps with deep system dependencies

🧼 Tips to Save More Space

Move Photos and Videos to the external drive.
Delete GarageBand loops, iMovie libraries, and Xcode simulators.
Use apps like CleanMyMac X (or free alternatives like DaisyDisk or OmniDiskSweeper) to find large unused files.

Final Thoughts

While moving apps to an external drive can help free up space, consider upgrading your storage or using cloud storage for large files if this becomes a regular issue.
