Top MacOS High Sierra Problems And How to Fix Them

MacOS High Sierra - MacBook Pro

Several months after Apple officially released their latest operating system update, the macOS High Sierra, to the public some of its users are still experiencing different types of problems and errors. While Apple is known for developing and offering top-notch software and hardware, performance issues cannot be totally avoided. Fortunately, there’s a solution for every macOS high sierra problem you might be experiencing right now. Here are some of the top masOS High Sierra problems and how to fix them.

1. Mac Won’t Start After Upgrading To macOS High Sierra

If your Mac is not starting an OS upgrade, do not worry because it is not an OS-exclusive problem. This was also one of the main reported problems when El Capitan was released and that users had and have been encountering this before. When your Mac refuses to boot up after installing High Sierra, you can try an NVRAM or PRAM reset.

NVRAM (non-volatile RAM) and PRAM (parameter RAM) are small RAMs that store particular Mac settings. Modern Macs have NVRAM while older models have PRAM. When you turn off your computer, these RAMs do not fully shut down as they are powered by a separate battery or capacitor in the motherboard. When they become corrupted, they are likely to prevent your Mac from booting up. The only way to stop them from doing so is to reset them.

To help you boot your Mac from scratch, here’s how you can reset the NVRAM or PRAM:

Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.

  • Press the Power button while pressing down on Option, Command, P, and R keys all at the same time.
  • Wait until the second startup sound or chime before releasing the buttons altogether.

Once your NVRAM or PRAM resets, consider launching Disk Utility to scan for other problems that may be preventing your Mac from starting up. Similarly, you can use a third-party tool like Mac repair app to easily and quickly look for problems to get rid of them.

2. MacOS High Sierra Slows Down or Freezes Randomly

If you just finished installing High Sierra, give your Mac some time to adjust and configure itself. If it’s still too slow or if it freezes randomly, try restarting. If this doesn’t do anything, you’d want to know what’s making it slow. To do this, launch Activity Monitor, which can be found in the Applications folder. Pay attention to apps eating up the CPU space, then force quit individual apps.

You might also need to delete system caches, which are temporary files left by programs. Over time, they can pile up and cause software conflicts. To clear cache folders manually, follow these steps:

  • Go to Finder > Go menu. Click on Go to Folder.
  • Type in ~/Library/Caches. Press Return/Enter.
  • Go through each folder to clean out the files inside them. Note: Do not delete the folders, only the files.
  • When you are done deleting old cache files, rename ~/Library/Caches to /Library/Caches.

Note that some cache files might still be needed to run certain programs properly, so be careful as to which cache files you need to delete. If you don’t want to do this manually and make a huge mistake, use a3rd party tool to do the job for you with just one click of a button.

3. Apps Freeze and Crash After Upgrading to macOS High Sierra

Apple has completely moved from 32-bit apps to the 64-bit structure with the High Sierra release. While most app developers have already prepared for the change, there are those who are yet to keep up.

If an app repeatedly freezes and crashes after you installed macOS High Sierra, check if an update is available for it. If there is, go ahead and update the app. Re-setting the app might help, but if not, you may need to uninstall it.

Uninstalling apps on a Mac can be complex. Tools like Outbyte macAries offer a more automated approach for removing apps and their associated files. Make sure to check if this solution is appropriate for you.

4. Slow Wi-Fi on macOS High Sierra

Nowadays, you’d rarely find anyone who doesn’t rely on wireless connectivity especially when it concerns the Internet that is why a slow net speed is a no-no. This is especially true if you’re using Macs which are designed to be the best of its class. Resetting current Wi-Fi settings can help solve the problem. To do this, here are the steps:

  • Launch Finder.
  • Press Command + Shift + G.
  • Type in the following: /Library/Preferences/SystemConfiguration/
  • Within the directory, select all files with the .plist file extension, then move them to the Trash.
  • Now, restart your Mac and router for the changes to apply. When your Mac comes back to life, it will create a fresh set of available Wi-Fi connections and settings.
