5 most annoying macOS High Sierra problems and how to fix them

macOS High Sierra is officially available for all Mac owners worldwide. Apple’s newest macOS version adds small and welcome changes to the operating system, encouraging users to upgrade. However, macOS High Sierra still has its own issues that may make your experience less joyful.

We have heard some of the issues Mac owners are facing with macOS High Sierra, ranging from issues with apps to Mac running slowly after the update. If you have just updated your Mac to macOS High Sierra and you are dealing with above-mentioned issues, don’t freak out because we are here to help.

In this article, we have created a list of the five most common macOS High Sierra problems and will show you how to fix them. Keep in mind that we recommend you back up your Mac before trying to update your machine.

  1. macOS High Sierra has failed to download

A lot of Mac owners have reported that they get a message that says “macOS High Sierra dowload has failed” when trying to install Apple’s newest version of macOS. There are several reasons why macOS High Sierra won’t download on your device. However, it’s mostly because you are trying to download the update on the release day.

The best shot now is to pause the download and try again. Besides, make sure you are still connected to a network (you can switch to an Ethernet cable for a better connection). If the problem still persists, delete the macOS High Sierra download file, reboot your Mac and try re-downloading the update.

  1. Mac fails to start after the update

We have got several complaints from Mac owners that their machine fails to start after updating to macOS High Sierra. If you are experiencing the issue, we recommend you restart the NVRAM on your Mac. To do this, turn off your computer, then turn it back on and hold down four keys together Option, Command, P, and R for 20 seconds.

Hold down those keys until your Mac reboots and you hear the startup chime. Release those keys and your Mac will reboot normally. This will bring your Mac into Safe mode. Now just simply run Disk Utility to see if the problem is fixed. If nothing happens, make sure you read on.

  1. macOS High Sierra keeps logging you out

If macOS High Sierra keeps logging you out of your Mac, don’t freak out because we are here to help. To fix the issue, click on the Apple menu at the top left corner of the screen, select System Preferences from the pull-down menu and select Security & Privacy. After that, click on Advanced and untick the box next to Log out of…minutes of inactivity.

If you are automatically logged out of your Mac in Google Chrome, make sure you disable hardware acceleration. To do this, open Google Chrome on your Mac, click on Settings and hit Advanced.

  1. Mac running slowly

If you have recently noticed that your Mac is running slowly after updating to macOS High Sierra, we believe that we can help you out. Before trying to do anything, make sure you restart your Mac to see if the problem is dealt with. If nothing happens, make sure you read on.

Find which apps are taking a lot of RAM on your device and kill them. To do this, open Activity Monitor on your device and force quit all the apps that are eating up your system’s memory.

  1. Apps fail to work in macOS High Sierra

A lot of Mac owners have recently claimed that some of their favorite apps like Final Cut Pro X 10.3.4, Motion 5.3.2 or Logic Pro X 10.3.1 fail to work in macOS High Sierra. If this is your case, there is a good chance that you are running older versions of those apps. So, it’s a good idea to update your apps to a newer version. To do this, head to the Mac App Store and update your apps.
