What to Do If macOS High Sierra Freezes and Stops?

Some Apple computer owners complaint that after the installation of the latest macOS High Sierra the system sometimes slows down and doesn’t work smoothly. Under such circumstances, scolding the Apple company is not the most useful thing to do, so we have prepared the real solutions to the problem.

It is also worth noting that with each update of the macOS the system requirements to computers’ hardware rise, which may also be the reason for its unsatisfactory performance. The problem is especially noticeable on Apple models of computers with HDD-disk. Therefore, many users replace them with ultra-fast and reliable SSDs.

Do not rush to conclusions

There is an opinion that often after updating the OS, the computer needs some time to fully update all services and re-index files. On powerful computers, this procedure can last several minutes, on weaker ones – up to a couple of hours. Therefore, you do not need to rush to undertake some immediate actions after the update.

Why does macOS High Sierra freeze?

There are a lot of reports from users that Apple computers with macOS High Sierra freeze or crashes and do not react to any user’s actions. Some claim that the keyboard doesn’t work and the cursor doesn’t move while the music continues to play.

  • Most often this happens after the viewing video on YouTube, Facebook, etc. In this instance, the computer should be rebooted. To avoid such a problem in the future, try installing and using another Internet browser. Apart from Apple’s Safari, this can be Mozilla Firefox, Opera or Google Chrome – the final choice is yours.
  • Sometimes, this type of error occurs because of the incompatibility of macOS and third-party applications. You need to update all apps to the most recent versions.
  • If this does not help, you can try a more fundamental way: roll back the operating system with the help of Time Machine.
  • Reduced productivity of your machine can also be associated with the background tasks, including Siri, iCloud, Search, Photo, etc. In that case, you just need to quit these tasks or leave the computer on for a while to allow it to complete all the background processes.

On the other hand, many Macs work faster after installing macOS High Sierra updates, especially when copying/moving files. This is most likely thanks to the recent APFS file system.

If even after a considerable wait the speed of Mac operation didn’t improve, it would not hurt to check how much memory is consumed by specific apps and services. You can do this using Activity Monitor. Sometimes, the system is slowed by some apps that consume a lot of resources.

What to do If nothing helps?

The radical way of solving the issue is reinstalling the OS from scratch. Otherwise, you’d better contact the service center as the problem might be with a hardware (for example, failing hard drive).
