It's important to understand that factory resetting a MacBook Pro without the password requires entering Recovery Mode. This process will erase everything on your hard drive, so make sure you have a Backup (Time Machine or otherwise) if possible. If you can't backup your files, they will be lost. Here's how to do it:

1. Start in Recovery Mode: Shut down your MacBook Pro completely. Then, press the power button and immediately hold down either:

   • Command (⌘) + R: To reinstall the latest macOS that was previously installed on your Mac.
   • Option (⌥) + Command (⌘) + R: To upgrade to the latest macOS that is compatible with your Mac.
   • Shift (⇧) + Option (⌥) + Command (⌘) + R: To install the macOS that came with your Mac, or the closest version still available.

   Continue holding the keys until you see the Apple logo or a spinning globe.

2. Open Disk Utility: Once the macOS Utilities window appears, select "Disk Utility" and click "Continue."

3. Erase your Startup Disk: In Disk Utility, select your startup disk (usually "Macintosh HD") in the sidebar. Click "Erase" at the top of the window.

   • Give the disk a name (you can use "Macintosh HD" again).
   • Choose "APFS" or "Mac OS Extended (Journaled)" as the format. APFS is recommended for SSDs, which are common in newer MacBook Pros. Mac OS Extended (Journaled) might be needed for older Macs.
   • Click "Erase."

4. Reinstall macOS: After the disk is erased, quit Disk Utility. You'll be back in the macOS Utilities window. Select "Reinstall macOS" and click "Continue." Follow the on-screen instructions to reinstall the operating system. The mac will need to download MacOS%20Image from the internet.

5. Activation Lock: If your MacBook Pro has Activation%20Lock enabled (tied to an Apple ID), you might still need the Apple ID and password associated with the device. If you don't know the Apple ID, you will need to contact Apple Support with proof of purchase.

Important Notes:

• This process will remove all data from your MacBook Pro.
• Ensure your MacBook Pro is connected to a stable Wi-Fi network during the macOS reinstallation.
• If you have a firmware password enabled, you will need to enter it before you can erase the disk.
• For older Mac OS versions the steps might be slightly different.
