How to Start Mac in Recovery Mode? | Step-by-Step Guide

Start Mac in Recovery Mode

Start Mac in Recovery Mode

Starting a Mac in Recovery Mode is a powerful troubleshooting step that allows you to repair disks, reinstall macOS, restore from backups, or reset settings, which can address issues like boot failures, corrupted USB drives , or installation problems with macOS Sequoia.

Recovery Mode loads a lightweight macOS environment from a separate partition or the internet, independent of your main system.

Below is a detailed step-by-step guide to start Recovery Mode on both Intel-based and Apple Silicon Macs, tailored to your macOS (e.g., Sequoia).

I’ll also cover variations like Internet Recovery and common uses, linking to your interests in USB recovery, SMC/NVRAM resets, and macOS installations.


What is Recovery Mode?

  • Purpose: Provides tools to fix macOS issues without a full OS boot.
  • Features:
  • Disk Utility: Repair or erase disks (e.g., corrupted USB).
  • Reinstall macOS: Download and install macOS (e.g., Sequoia) without losing data (if possible).
  • Time Machine: Restore from backups.
  • Terminal: Run commands (e.g., reset passwords, clear NVRAM).
  • Startup Security (Apple Silicon): Adjust security settings.
  • Types:
  • Standard Recovery: Uses a local recovery partition (faster, ~500MB).
  • Internet Recovery: Downloads recovery OS from Apple servers (slower, needs Wi-Fi).

When to Use Recovery Mode

  • Boot Issues: Mac shows a question mark, prohibitory symbol, or black screen (like your prior macOS installation question).
  • Disk Problems: Corrupted internal drive or USB (e.g., your formatted USB recovery query).
  • macOS Installation: Reinstall Sequoia after USB installer fails.
  • Performance: Slowdowns or crashes not fixed by SMC/NVRAM resets (your recent questions).
  • Security: Reset passwords, disable FileVault, or change firmware settings.
  • Data Recovery: Access Terminal to salvage files before erasing.

Step-by-Step Guide to Start Recovery Mode

The process differs between Intel-based Macs and Apple Silicon (M1/M2/M3/M4) Macs due to their boot architectures.

Step 1: Identify Your Mac Model

  • Check Model:
  • Apple menu () > About This Mac.
  • Examples:
    • Intel: MacBook Pro (2019, Intel Core i7).
    • Apple Silicon: MacBook Air (2023, M2).
  • Or in Terminal: system_profiler SPHardwareDataType
    • Look for “Model Name” and “Chip” (e.g., Intel Core i5 or Apple M4).
  • Why It Matters: Intel Macs use key combos; Apple Silicon uses a Startup Options menu.

Step 2: Save Work and Shut Down

  • Close Apps: Save any open files (e.g., recovered USB data from your 4DDiG question).
  • Shut Down:
  • Apple menu > Shut Down > Wait 30 seconds until fully off.
  • If unresponsive (e.g., power issues from your SMC question):
    • Intel: Hold power button for 10 seconds.
    • Apple Silicon: Hold power button for 20 seconds.

Step 3: Boot into Recovery Mode

Apple Silicon Macs (M1, M2, M3, M4: 2020-2025)
  • Models: MacBook Air (2020-2024), MacBook Pro (2021-2024), Mac mini (2023), iMac (2021+), Mac Studio, Mac Pro (2023).
  • Steps:
  1. Ensure the Mac is off.
  2. Press and hold the power button until “Loading startup options” appears (~10-20 seconds).
    • You’ll see a gear icon and disk volumes (e.g., “Macintosh HD”).
  3. Release the power button.
  4. Click Options (gear icon) > Continue.
  5. If prompted, select a user with admin privileges > Enter password > Click Next.
  6. The Recovery Mode screen loads with utilities: Disk Utility, Reinstall macOS Sequoia, Restore from Time Machine, Terminal, etc.
  • Time: ~30 seconds to load (faster with a local recovery partition).
Intel-Based Macs (Pre-2020)
  • Models: MacBook Pro (2006-2020), MacBook Air (2008-2020), iMac (2006-2020), Mac mini (2006-2018).
  • Steps:
  1. Ensure the Mac is off.
  2. Press the power button to start.
  3. Immediately press and hold Command (⌘) + R.
    • Hold until the Apple logo or loading bar appears (~10-20 seconds).
  4. Release the keys.
  5. If prompted, select a Wi-Fi network (for Internet Recovery fallback).
  6. Enter an admin password if FileVault is enabled.
  7. The Recovery Mode screen appears with the same utilities as above.
  • Time: ~30-60 seconds (longer if it falls back to Internet Recovery).
Special Case: Macs with T2 Chip (Intel, 2018-2020)
  • Models: MacBook Pro (2018-2020), MacBook Air (2018-2020), iMac (2020), Mac mini (2018).
  • Steps: Identical to Intel Macs:
  1. Shut down.
  2. Press power button, then hold Command + R until the Apple logo.
  3. Select admin user/password if prompted.
  • Note: T2 Macs may require SMC/NVRAM resets first (your prior questions) if boot issues persist.

Step 4: Use Recovery Mode Tools

  • Disk Utility:
  • Select your internal drive (e.g., “Macintosh HD”) or USB (e.g., “SanDisk 16GB” from your recovery question).
  • Click First Aid to repair file system errors.
  • If corrupted, erase as APFS (or Mac OS Extended for older Macs) > Reinstall macOS.
  • Reinstall macOS Sequoia:
  • Choose Reinstall macOS Sequoia > Continue.
  • Follow prompts to download (~12GB, needs internet) and install without erasing data (unless you erased the disk).
  • Use your Sequoia USB installer (from your prior question) if offline:
    • Shut down, insert USB, boot with Option (⌥), select “Install macOS Sequoia.”
  • Restore from Time Machine:
  • Select a backup to restore files/settings.
  • Terminal:
  • Reset NVRAM manually (your recent question):
    nvram -c reboot
  • Reset password:
    resetpassword
  • Startup Security Utility (Apple Silicon):
  • Adjust Secure Boot or external boot settings (e.g., for USB installers).

Step 5: Exit Recovery Mode

  • Restart:
  • Click Apple menu (top-left) > Restart.
  • Or select Shut Down to power off.
  • Boot Normally:
  • If no startup disk is set, hold Option (⌥) and choose “Macintosh HD.”
  • Verify Fix:
  • Check if the original issue (e.g., boot failure, USB not mounting) is resolved.
  • For USB recovery, reinsert and check Finder or Disk Utility.

Step 6: Try Internet Recovery (If Standard Recovery Fails)

  • Why: No local recovery partition (e.g., erased drive, failed macOS install like your black screen issue).
  • Apple Silicon:
  1. Shut down.
  2. Hold power button until “Loading startup options.”
  3. Click Options > Connect to Wi-Fi > Continue.
  4. If it fails, macOS defaults to Internet Recovery (shows a globe).
  • Intel:
  1. Shut down.
  2. Press power button, then hold Command + Option + R.
  3. Release when a globe or “Starting Internet Recovery” appears.
  4. Connect to Wi-Fi when prompted.
  • Details:
  • Downloads recovery OS (~1GB, takes 5-20 minutes on fast Wi-Fi).
  • Loads same utilities but reinstalls the Mac’s original macOS (e.g., Monterey for a 2021 Mac) unless you specify Sequoia via USB.
  • Note: Slower than standard Recovery—ensure a stable connection.

Troubleshooting

  • Recovery Mode Won’t Load:
  • Intel: Ensure Command + R is pressed immediately (within 1-2 seconds). Retry with Command + Option + R for Internet Recovery.
  • Apple Silicon: Hold power button longer (~20 seconds) if no options appear.
  • Check keyboard (use a wired USB keyboard if built-in fails).
  • Black Screen or Error (Your Prior Question):
  • Try Internet Recovery (globe indicates it’s working).
  • Reset SMC/NVRAM first (your recent questions):
    • SMC: Power cycle (Apple Silicon) or key combo (Intel).
    • NVRAM: Command + Option + P + R (Intel) or nvram -c in Recovery.
  • If it persists, use your Sequoia USB installer (Option boot).
  • USB Not Detected (Your Recovery Context):
  • In Disk Utility (Recovery), check if the USB appears.
  • Run: diskutil list
    • Mount manually: diskutil mountDisk /dev/diskX (replace X with USB’s number).
  • If unreadable, use 4DDiG (your prior question) post-Recovery.
  • Wi-Fi Issues (Internet Recovery):
  • Select a 2.4GHz network for stability.
  • Use Ethernet if available (via USB-C adapter).
  • “No admin user” Prompt:
  • Enter any admin account password.
  • If forgotten, use Terminal’s resetpassword command.
