To boot your MacBook Pro M4 (which likely refers to a Mac with Apple silicon, such as the M4 chip, though Apple hasn't officially released an M4 chip for Macs as of my last update) into Recovery mode, follow these steps. Note that the process for Apple silicon Macs differs slightly from Intel-based Macs.
Steps for Apple Silicon Macs (e.g., M1, M2, M3, etc.)
1. Shut Down Your Mac: Ensure your MacBook is completely powered off.
2. Press and Hold the Power Button: Press the power button and hold it until you see the "Loading startup options" screen. This might take a few seconds.
3. Select Options: Click on Options and then click Continue.
4. Enter Administrator Password: You will be prompted to enter the password for an administrator account on your Mac. Select the account and enter the password, then click Continue.
5. Access Recovery Mode: Once you've logged in, you will enter the Recovery mode environment. Here, you can access various utilities such as Disk Utility, Reinstall macOS, and more.
Common Recovery Mode Options
- Disk Utility: Use this to manage disks, erase volumes, or repair disk permissions.
- Reinstall macOS: Reinstall the operating system. Ensure you're connected to the internet.
- Get Online Help: Access Apple's support resources directly from Recovery mode.
- Startup Security Utility: Adjust security settings related to booting and software installation.
Note on M4 Chip
As of my last update, Apple has not released a Mac with an M4 chip. The instructions provided are for Apple silicon Macs, which include M1, M2, and M3 chips. If your Mac uses a different processor, ensure you follow the appropriate instructions for that model.
