How to wipe Mac mini to factory settings

Welcome to the Apple Support Communities.

If you just need to erase your Mac mini, see the article that applies to you:

• Erasing an Intel-based Mac: Use Disk Utility to erase an Intel-based Mac - Apple Support
• Erasing a Mac with Apple Silicon: Use Disk Utility to erase a Mac with Apple silicon - Apple Support

If you are selling, giving away, or trading in your Mac, see: What to do before you sell, give away, or trade in your Mac - Apple Support.
