How to Use macOS Recovery Mode: A Complete Guide

Introduction / Why This Is Needed

macOS Recovery Mode is a special boot environment that allows you to perform critical system actions even when the system is not functioning. With it, you can:

• Diagnose and repair the disk using Disk Utility (First Aid, unmounting, formatting).
• Restore the system from a Time Machine backup.
• Reinstall macOS without data loss (if the volume is not erased) or with a full disk wipe.
• Reset your account password or erase all data (Apple Silicon only).
• Clear NVRAM/PRAM cache and update firmware.

This guide applies to Macs with both Intel and Apple Silicon (M1/M2/M3) processors. The entry procedure differs, but the set of utilities is generally the same.

Requirements / Preparation

Before you begin, ensure that:

1. Your Mac is charged to at least 50% or is connected to power.
2. You have access to stable internet if you plan to perform internet recovery or reinstall macOS.
3. A backup has been created via Time Machine. Using some tools (e.g., unmounting the disk) can lead to data loss.
4. You know the administrator password for certain operations (e.g., unmounting the disk).
5. For Apple Silicon, a network connection (Wi-Fi or Ethernet) is required to boot the recovery environment if the built-in partition is damaged.

Step 1: Entering Recovery Mode (Different Methods)

The method depends on the processor architecture.

For Macs with Intel (up to 2020)

1. Shut down your Mac via the Apple menu () → "Shut Down".
2. Turn on your Mac and immediately hold the Command (⌘) + R keys.
3. Release the keys when you see the Apple boot screen or globe icon (internet recovery).
4. After booting, the "macOS Utilities" window will appear.

⚠️ Important: If you want internet recovery (booting from Apple's servers), hold Option+Command+R. For the last installed version of macOS, hold Shift+Option+Command+R.

For Macs with Apple Silicon (M1/M2/M3, 2020+)

1. Completely shut down your Mac.
2. Press and hold the power button until the startup options screen appears (containing "Options", "Macintosh HD", and other volumes).
3. Click "Options" (or "Options"), then "Continue".
4. After booting, the "macOS Utilities" window will appear.

💡 Tip: If your Mac fails to boot into Recovery Mode, connect it to the network via Ethernet or ensure Wi-Fi is available. Apple Silicon always boots the latest compatible version of macOS.

Step 2: Overview of Available Utilities

In the "macOS Utilities" window, you will find the following key tools:

• Disk Utility — the primary tool for disk operations: First Aid, unmounting, formatting, creating partitions.
• Restore from Time Machine — restore the entire system or individual files from a backup.
• Reinstall macOS — install macOS over the current system without deleting user files (if you select the same volume) or with a full disk wipe.
• Terminal — access to the command line for manual operations (e.g., mounting disks, resetting passwords).
• Safari — a browser to search for solutions online (works without extensions).
• Disk Utility in "Recovery" mode — may be unavailable if the recovery partition is damaged.

Step 3: Using Disk Utility for Disk Diagnosis and Repair

Disk Utility is the most common reason for entering Recovery Mode.

1. In the "macOS Utilities" window, double-click "Disk Utility".
2. In the left panel, select the main volume (usually named Macintosh HD or Apple SSD).
3. Click "First Aid" → "Run".
4. Wait for the check to complete. If First Aid finds and fixes errors, restart your Mac and check if the problem is resolved.
5. If First Aid doesn't help, you may need to unmount the disk and format it (this will delete all data!). To do this:
   • Select the physical disk (e.g., Apple SSD AP0256J), not the volume.
   • Click "Erase", assign a name (e.g., Macintosh HD), set format to APFS and scheme to GUID Partition Map.
   • After formatting, close Disk Utility and return to the main menu to reinstall macOS.

Step 4: Restoring the System from Time Machine

If you have a backup on an external drive:

1. In the main "macOS Utilities" window, select "Restore from Time Machine".
2. Click "Continue".
3. Select the backup (date) from the list.
4. Select the destination disk (usually Macintosh HD).
5. Start the restore. The process can take from several minutes to several hours, depending on the backup size.
6. After completion, your Mac will restart with the restored system.

Step 5: Reinstalling macOS

If the system is severely damaged or you want to "clean" your Mac:

1. In the main "macOS Utilities" window, select "Reinstall macOS".
2. Click "Continue" and follow the on-screen instructions.
3. Select the volume for installation (usually Macintosh HD). If you want to completely wipe the disk, format it first via Disk Utility.
4. Important: Reinstallation does not delete your user files if you select the same volume and do not format it. However, for guaranteed safety, having a backup is best.
5. Your Mac will download macOS from the internet (connection required) or from the built-in partition. Installation may take 30–60 minutes.
6. After completion, your Mac will restart and prompt you to go through the setup (create an account, sign in to iCloud, etc.).

Step 6: Additional Actions (Terminal, Password Reset)

Resetting your account password

1. In the main window, select "Terminal".
2. Enter the command:

   resetpassword
   

3. Press Enter. The password reset utility will open. Select the volume, account, and set a new password.

Reset NVRAM/PRAM (Intel only)

• After exiting Recovery Mode, restart your Mac and immediately hold Option+Command+P+R for 20 seconds.

Erasing all data (Apple Silicon)

• In the main "macOS Utilities" window, select "Erase All Content and Settings" (requires entering the administrator password). This will permanently delete all data and restore the Mac to factory settings.

Verifying the Result

After performing the necessary action:

1. Restart your Mac via the "macOS Utilities" menu → "Restart".
2. If you repaired the disk — check if the system boots normally, and if there are no errors when opening files.
3. If you restored from Time Machine — ensure your files and applications are in place.
4. If you reinstalled macOS — go through the initial setup and check Wi-Fi, Bluetooth, and sound functionality.
5. If the problem persists — the disk may need replacement (hardware failure) or deeper diagnostics may be required.

Potential Issues

Issue: Mac won't boot into Recovery Mode (just a black screen or stuck on the Apple logo)

Solution:

• For Intel: try internet recovery (Option+Command+R).
• For Apple Silicon: ensure the Mac is connected to the network (Wi-Fi/Ethernet). If the network is unavailable, create a hotspot with your iPhone (in the "Personal Hotspot" section).
• If that doesn't help, the Mac may have a hardware problem (e.g., a faulty drive). Contact Apple Support.

Issue: No internet in Recovery Mode

Solution:

• Intel: in the boot window, select a Wi-Fi network via the menu in the top-right corner.
• Apple Silicon: internet is required to load the recovery environment. Connect the Mac directly to your router with an Ethernet cable (using a USB-C to Ethernet adapter) or create a hotspot with your iPhone.

Issue: Disk Utility doesn't see the disk or shows "Error"

Solution:

• This often indicates a physical drive failure (SSD/HDD). Try internet recovery and reinstalling macOS. If the disk is not detected, the drive needs replacement at a service center.

Issue: After reinstalling macOS, Mac asks to activate with Apple ID, but I forgot the password

Solution:

• This is Activation Lock for Apple Silicon. You will need the Apple ID and password previously used on this Mac. If you've forgotten them, recover access via iforgot.apple.com. Without this, the Mac will remain locked.

Issue: Time Machine restore doesn't see the backup

Solution:

• Ensure the external drive is connected directly to the Mac (not through a USB hub).
• The disk must be formatted as APFS or Mac OS Extended (Journaled).
• If the backup was created on a newer version of macOS, it may not appear on an older system. Try internet recovery to the same macOS version as the backup.

Final Recommendations

macOS Recovery Mode is a powerful yet simple tool. Always create a backup before performing disk operations. For everyday issues (slow performance, app errors), try standard methods first: restart, update macOS, clear caches. Use Recovery Mode only for critical system failures or when preparing your Mac for sale (erasing data).

If the problem persists after all manipulations, the issue may be hardware-related (disk, memory, logic board). In this case, contact official Apple Support or an authorized service center.
