macOS High Sierra: Troubleshooting Common Issues

macOS High Sierra, released in September 2017, introduced significant improvements and new features to the macOS operating system. While generally stable, users may encounter various issues during installation or everyday use. This comprehensive guide will provide troubleshooting tips for common macOS High Sierra problems.

Installation Issues

  • Installation Failure: If MacOS High Sierra fails to install, ensure your Mac meets the minimum system requirements. Check for sufficient storage space and verify that the installer is not corrupted.
  • Slow Installation: The installation process can be time-consuming, especially on older Macs or with limited storage. Ensure your Mac is connected to a stable Wi-Fi network and avoid running other resource-intensive tasks during the installation.
  • Installation Freezing: If the installation process freezes, try restarting your Mac and retrying the installation. If the issue persists, create a bootable macOS High Sierra installer on an external drive and try installing from there.

Startup Issues

  • Mac Won’t Start: If your Mac won’t start after updating to macOS High Sierra, try booting into Safe Mode by holding down the Shift key during startup. This can help isolate and resolve startup issues.
  • Startup Disk Errors: If your startup disk is corrupted, you may encounter startup errors. Use Disk Utility in Recovery Mode to repair the disk.
  • NVRAM or PRAM Reset: If you’re experiencing startup issues, resetting the NVRAM or PRAM can sometimes resolve the problem. Hold down the Command, Option, P, and R keys during startup until you hear the startup chime for the second time.
