What is an Unrecoverable Error?

An unrecoverable error is a fatal system error that prevents Mac OS from booting up or functioning correctly. It is different from a regular error because the system cannot recover from it automatically. The only way to fix an unrecoverable error is through manual troubleshooting and intervention.

Unrecoverable errors often occur due to file system corruption, installation failures, hardware problems, or software incompatibilities. They can cause the system to freeze, crash repeatedly, or fail to start up. Since the system cannot fix the error on its own, users need to investigate the cause and apply the appropriate solutions.

The Most Common Unrecoverable Errors in 2023

Here are some of the most reported unrecoverable errors Mac users encountered in 2023 and how to troubleshoot them:

1. “An error occurred while preparing the installation”

This error occurs when trying to install or update macOS and indicates the installer data is corrupted. It prevents the installation from completing.

Possible solutions:

  • Retry installing macOS. The data may download properly on the next attempt.
  • Use a different internet connection or network to download the installer again.
  • Try installing from a USB installer instead of downloading from the App Store.
  • Recreate the macOS installer USB drive if corrupted.

2. “Security Agent was unable to create requested mechanism”

This error indicates a problem with security permissions and mechanisms in Mac OS. It can occur when enabling FileVault encryption or installing certain apps.

Possible solutions:

  • Boot into recovery mode and reinstall macOS. This will reset permissions and certificates.
  • Delete affected kext files from System/Library folders and reboot.
  • Reset NVRAM and SMC to clear out old data.

3. “This copy of the Install macOS [Version Name] application is damaged”

This refers to corruption in the macOS installer app that prevents installation. The app becomes unusable.

Possible solutions:

  • Delete the installer from the Applications folder and redownload it from the App Store.
  • Create a bootable installer on a USB drive instead of using the app.
  • Try downloading the installer on a different network. Slow/intermittent connections can cause corruption.

4. “macOS could not be installed on your computer”

This generic error indicates the macOS installation failed due to issues with hard drive permissions, storage corruption, or hardware faults.

Possible solutions:

  • Boot into recovery mode and run Disk Utility to check for errors.
  • Repair disk permissions in Disk Utility.
  • Reset NVRAM and SMC.
  • Try installing macOS on an external drive to isolate hard drive issues.

5. “An error occurred while preparing the update”

Similar to error 1, this message indicates corrupted files when trying to install a macOS update. It fails the verification check.

Possible solutions:

  • Delete the macOS Installer under /Applications and redownload the update.
  • Create a bootable installer on a USB drive.
  • Use a different network connection to redownload the update.

6. “Installation failed with error: POWERPC_BOOT_VERSION_TOO_OLD”

This error occurs when trying to install an OS version that is older than the current boot ROM. For example, installing OS X Snow Leopard on newer Macs.

Possible solutions:

  • Check compatibility and install a supported macOS version for your Mac.
  • Some workarounds exist by editing boot files but have risks.

Tips for Troubleshooting Unrecoverable Errors

Follow these tips when troubleshooting unrecoverable errors on your Mac:

  • Boot into recovery mode or Internet recovery mode to access Disk Utility and terminal.
  • Use Disk Utility to verify/repair disk errors and permission issues.
  • Reset NVRAM and SMC to clear old settings and boot caches.
  • Create a bootable macOS USB installer drive for reinstallation.
  • Determine if the error occurs when booting from an external drive. This can isolate hardware issues.
  • Back up important data before making major system changes and reinstallations.
  • Research the specific error code or message to find known solutions. Apple communities and forums are helpful.
  • Try installing macOS updates individually to pinpoint any problematic updates.
  • Seek help from Apple tech support if available or an expert technician for tough errors.

Common Causes of Unrecoverable Errors

Understanding the potential causes of unrecoverable errors can aid troubleshooting:

  • Corrupted system files: Critical OS files get damaged, often during installations/updates.
  • Drive errors: The Mac hard drive has developed bad sectors, formatting issues, or file system corruption.
  • Incompatible hardware: Certain Mac hardware components are not fully supported by the installed OS.
  • Faulty RAM: Memory problems can lead to crashes and boot failures.
  • Software conflicts: Installing/uninstalling apps incorrectly can break required OS processes.
  • Permissions issues: Incorrect file/drive permissions prevent accessing critical system resources.
  • Outdated firmware: Old EFI, SMC or BIOS firmware versions may be incompatible.

When to Seek Professional Help

If you have attempted all recommended fixes and the unrecoverable error persists, it is wise to seek professional help. A qualified technician can perform advanced troubleshooting and diagnostics to identify any underlying hardware issues. They have access to internal tools, replacement parts and OS debugging capabilities beyond what typical users can attempt.

For severe errors that completely block system bootup, professional assistance is the fastest solution. Seeking help promptly can prevent permanent data loss and avoid invasive reinstallation procedures.


Unrecoverable errors require patience and care to fix. Try not to force-quit or hard restart the Mac as this can further corrupt files. Instead, research the specifics of the error online to find proven solutions. Determining the underlying cause, whether software flaws or hardware faults, is key to resolving the issue for good. Maintaining backups and being cautious during system modifications can also prevent these errors from occurring in the first place.
