Solving the 'Required Firmware Update Could Not Be Installed' Error on MacBook Air 2017

If you're encountering the message 'A required firmware update could not be installed' while trying to update your MacBook Air 2017 from macOS Mojave to Monterey, this article will guide you through several trouble-shooting steps to resolve this issue effectively.

Check System Requirements

Ensure that your MacBook Air 2017 meets the system requirements for macOS Monterey. The 2017 model typically should be compatible, but it's always a good idea to double-check these requirements. You can find the detailed system requirements by visiting Apple'sofficial website.

Backup Your Data

Before you proceed with any troubleshooting, make sure to back up your important data using Time Machine or another trusted backup method. Losing data during an update can lead to frustration and potential data loss.

Free Up Disk Space

Ensure you have enough free disk space for the update. macOS Monterey typically requires about 20 GB of free space to install. You can check your storage by going to Apple Menu About This Mac Storage.

Reset NVRAM/PRAM

If your issue persists, try resetting the Non-Volatile Random Access Memory (NVRAM) or Parameter Random Access Memory (PRAM).

Shut down your Mac. Turn it back on and immediately press and hold Option Command P R for about 20 seconds. Release the keys after you hear the startup sound or see the Apple logo.

Reset SMC System Management Controller

If the above step does not resolve the issue, try resetting the System Management Controller (SMC).

Shut down your Mac. Press and hold Shift Control Option on the left side of the built-in keyboard, then press the power button simultaneously. Hold these keys for 10 seconds, then release them and turn on your Mac.

Update from Safe Mode

If the SMC reset does not work, try booting your Mac in Safe Mode and attempting to update macOS again.

Restart your Mac and hold the Shift key immediately after you hear the startup sound. This will boot your Mac in Safe Mode. Once in Safe Mode, try updating macOS again.

Use macOS Recovery

If the Safe Mode update fails, consider using macOS Recovery to reinstall the latest version of macOS compatible with your device.

Restart your Mac and hold the Command R keys until you see the Apple logo or a spinning globe. In macOS Recovery, choose Reinstall macOS. This should install the latest version of macOS that is compatible with your device.

Check for Firmware Updates

Some firmware updates can be installed separately. Go to Apple Menu About This Mac Software Update to check for any firmware updates that may be available.

Install from USB

If none of the above steps work, consider creating a bootable USB installer for macOS Monterey. You can download the installer from the App Store and use a USB drive to perform the installation.

Contact Apple Support

For persistent issues, it may be best to contact Apple Support for further assistance. They can provide personalized support and troubleshooting steps based on your specific situation.

Following these steps should help you resolve the firmware update error and successfully update to macOS Monterey. If you follow them diligently, you should be able to enjoy the latest features and improvements provided by macOS Monterey without hesitation.
