Prior to a Frozen High Sierra Installation

Whenever Apple releases an update for High Sierra, many Mac users will rush to download it. Because of that, Apple’s servers slow down. Thus, your first course of action should be to check the System Status page of Apple and see macOS Software Update to find out if there are problems.

How to Know If the Installation Has Stalled
Generally, if there is a problem with the software installation, it will show on the screen. In some cases, an Apple logo with a loading status bar will show. Sometimes, you will see a “spinning beach ball”. On some other Macs, the screen will turn white, black, or grey that one cannot tell if the Mac is switched on or not.
Alternatively, you may also find your Mac frozen on the installation page with a message saying, “macOS could not be installed on your computer.” And if you click the Restart button, the same message will show.
As you can see, your Mac has many ways of telling you that the installation of Mac OS has stalled. But before you take action, you have to be sure that the installation is no longer running in the background. Otherwise, you might lose your data when you interrupt the installation process with a forced reboot.
If you are uncertain whether or not your Mac has frozen during the installation, consider our advice below:
- Know if your Mac has really stalled.
Before you come up with a conclusion that your Mac has stalled during the installation, you have to be aware of certain things.
Sometimes, the High Sierra installation can take very long to the point that it looks frozen already, but when you leave it for hours, the process has eventually completed. So, it’s best that you leave your Mac overnight to complete the installation.
Generally, the installation of the updates can take 16 hours or more, and the status bar you see during the installation is only a guess at how long the installation will take.
- Check the Log to know if your Mac is still installing the update.
To bring up the Log, press the Command + L keys. It should show added information and details about the total time left for the installation. It will also give you a better idea of what files are currently being installed.
- Be patient.
If you think that the installation has not stalled, just be patient and wait for the process to be completed for a few more hours.
Fixes to a Stuck Mac OS Sierra Installation

- Restart your Mac.

Press and hold the Power button to switch off your Mac. Wait for a few seconds and restart your Mac.

- Install the Combo update.
As mentioned above, the Mac App Store is not the only place to download the High Sierra update from. You can also download it from Apple’s website.
We highly suggest you get your update from Apple’s website if you are having problems with the installation. If you visit the website, you can find the Combo update, which contains all the files needed to update your OS.

- Install the update in Safe mode.
To install the High Sierra update in Safe mode, press the Power button and hold down the Shift key. Once your Mac has restarted, go to the App Store and install the update in Safe mode. Then, reboot.
- Allocate more space.
One possible reason why the update failed is that there is not enough storage space available to perform the installation. While in Safe mode, you might as well start deleting some files.
- Reset your NVRAM.
If the installation in Safe mode still does not work, reset your NVRAM. Restart your Mac and then hold down the Command, Option, R and P keys. That should reset the NVRAM. Wait for a few seconds until your Mac restarts and wait if the installation starts.
- Start in Recovery mode to reinstall High Sierra.
You can also restart your Mac in Recovery mode by holding down the Command + R keys at startup. From here, you will be presented with a few options. But we suggest you select the Install new OS option.
While reinstalling your OS, your Mac will replace all the system files and overwrite the problematic ones which may cause the error.
