Upgrade Mac OS High Sierra: Fix Common Issues and Troubleshoot

Are you experiencing issues with your Mac after upgrading to macOS High Sierra? You're not alone. While the new operating system is generally problem-free, some users may encounter problems that can be frustrating and time-consuming to resolve. In this article, we'll explore common issues that arise during the upgrade process and provide troubleshooting steps to help you overcome them.

The Repeating Update Loop

One of the most common issues with macOS High Sierra is the repeating update loop. This occurs when your Mac tries to repeatedly update, causing it to become stuck in an endless loop. The culprit behind this problem is often a third-party app that's not compatible with the new APFS file system.

Identifying the Problem

To troubleshoot the issue, check your Console.app for errors from Sandboxd and Hidd (IOKit). If you're experiencing errors, it's likely due to a third-party software. Another potential cause is having a copy of macOS Server in your Applications folder.

Deleting the Installer

Try deleting the downloaded installer (located in your Applications folder) using CleanMyMac and downloading it again. This should resolve the issue if the problem lies with the installer.

Forcing Quit the Installer

If the download completes successfully but the installation doesn't finish, force quit the installer using the same procedure as above. To do this:

1. Launch the App Store app.

2. Go to the Purchases tab.

3. Select the macOS High Sierra installation and click 'Install.'

4. If the installation doesn't complete, select the App Store app and confirm you want to force quit.

5. Press Cmd-Alt-Esc or go to the Apple menu and choose Force Quit.

Resolving Common Issues

Here are some common issues that arise during the upgrade process:

* Download Fails: Try restarting the download by going back to the App Store, selecting the macOS High Sierra installation, and clicking 'Install' again.

* Installation Fails: If the installation fails after downloading, try force quitting the installer using the steps above.

Preventing Issues

To prevent issues with your upgrade, make sure you:

* Check if your Mac is compatible with macOS High Sierra before upgrading.

* Make a bootable backup of your data before starting the upgrade process.

By following these troubleshooting steps and taking preventive measures, you can ensure a smooth upgrade to macOS High Sierra. Remember, it's always a good idea to have a reliable backup tool at hand, such as Get Backup Pro (included with Setapp subscription).
