Troubleshooting macOS Recovery Mode

If you’re experiencing issues with your Mac and need to troubleshoot, macOS Recovery Mode can be a valuable tool. Here’s a concise guide to help you navigate and troubleshoot common problems in Recovery Mode.

1. Start by shutting down your Mac completely. Once it’s off, press and hold the power button to turn it back on.

2. As your Mac starts up, immediately press and hold the Command (⌘) and R keys together. Keep holding them until you see the Apple logo or a spinning globe.

3. When you enter Recovery Mode, you’ll see a menu with several options. The first step is to check your internet connection. Click on the Wi-Fi icon in the menu bar and select your network.

4. If you’re unable to connect to Wi-Fi, you can use an Ethernet cable to connect your Mac directly to the modem or router.

5. Once you’re connected to the internet, you can proceed with troubleshooting. If you’re having issues with your Mac’s startup disk, click on Disk Utility in the menu and select your disk. Then, click on First Aid to repair any disk errors.

6. If you’ve forgotten your Mac’s password and need to reset it, click on Utilities in the menu and select Terminal. Type “resetpassword” (without quotes) and press Enter. Follow the on-screen instructions to reset your password.

7. In some cases, you may need to reinstall macOS to resolve persistent issues. From the Recovery Mode menu, click on Reinstall macOS and follow the prompts to reinstall the operating system. This will not erase your personal data, but it’s always a good idea to have a backup before proceeding.

8. If you encounter any errors or issues during the reinstallation process, make note of any error messages and try again. If the problem persists, you may need to contact Apple Support for further assistance.

Remember to provide feedback about your experience in macOS Recovery Mode. This helps Apple improve their products and address any issues you may have encountered.


# Check if the USB drive is mounted
if [ ! -d "/Volumes/RecoveryUSB" ]; then
echo "Please mount a USB drive and name it 'RecoveryUSB'."
exit 1

# Prompt for administrator password
echo "Please enter your administrator password:"
read -s password

# Create the macOS recovery installer
sudo /Applications/Install\ macOS\ Big\ --volume /Volumes/RecoveryUSB --nointeraction

# Verify the process completion
if [ $? -eq 0 ]; then
echo "Mac recovery installer created successfully."
echo "Failed to create the recovery installer."

Please note that this code assumes you have downloaded the macOS Big Sur installer from the App Store and saved it in the default location (`/Applications`). It also assumes you have a USB drive mounted with the name “RecoveryUSB.” The code prompts for the administrator password since the `sudo` command is used to run the `createinstallmedia` tool with elevated privileges.

Keep in mind that this sample code only addresses the creation of a macOS recovery installer on a USB drive. It does not cover the entire range of tasks associated with Mac recovery installation.
