Every time Apple rolls out a new macOS update, no matter whether a minor version update or a major OS upgrade, some people would like to test it out fast. However, downloading and updating macOS is not always successful. Your Mac could be stuck on downloading the installer or on installing the new update. This article will troubleshoot the error and help you finish the macOS update successfully without any data loss.

The methods mentioned below apply to all macOS update stuck scenarios, but we will focus on a Mac that has a problem updating macOS Monterey. macOS Monterey is not officially released to the public yet, and macOS Monterey in this article represents macOS Montery Developer beta.

macOS Monterey update stuck while downloading

Before you can install and use the newer operating system, you must download an installation file in Software Update tool. If the loading bar seems to stop for a long while, you can try the following methods to fix the frozen downloading process.

Wait it out

The downloading of a operating system is not as fast as we usually expected to download a file from a web page. It can be extremely slow if Internet speed is slow or the installer file is large, especially you update to macOS Monterey from macOS 10.14 or below. Since you have started, we recommend you wait it out for at least one more hour. You probably will luck out to have a successful downloading.

Check system status

However, if you have waited for hours and still are experiencing an unfinished system software downloading, it's highly possible that Apple's services could be to blame. An influx of people would rush to download the update as soon as Apple releases the new macOS, especially the first day or first week. This can put Apple's services under pressure.

You can check the status of Apple's services by heading over to Apple's System Status page. Find the "macOS Software Update" in the list. If the accompanying icon is yellow or red, this indicates that Apple's services are too busy to support a complete update on your Mac now.

It is advisable that you quit the update and wait until next day when macOS update is available again.

Check your Internet

As aforementioned, poor Internet performance can lead to an extremely slow installer downloading. After you confirm everything is alright with Apple's support on macOS update, you can get your hands down to check if it is the slow Internet access stops the installer from downloading. You can check by saving a picture from a browser like Safari.

To speed up the Internet speed, you can:

  1. Reboot your router.
  2. Bring your Mac close to the router.
  3. Disconnect and reconnect to Wi-Fi.
  4. Use a different Wi-Fi connection.

Check disk space

A minor software update on Mac requires free space from several megabytes to several gigabytes while a major OS upgrade usually requires at least 12 gigabytes free capacity to download the updated macOS. The insufficient free space on Macintosh HD or full Mac disk will cause the failure in an updating process.

You need to cancel the update and delete some less-important files on your startup disk to free up more space.

If the installer has been successfully downloaded, but Mac won't install it and is stuck on the loading login screen or won't boot past Apple logo after your click "Upgrade Now". We conclude 6 ways below to help you finish the macOS Monterey installation.

Restart you Mac

Still, you should give the rebooting more time because it takes a while until the new macOS Monterey completely replaces the old one. If the progress bar is frozen for hours while rebooting, you can restart your Mac manually to cancel the installation. Then you can perform the update through Software Update again. The macOS update will usually resume from where you left off. If not, it will start from scratch.

Disable FileVault

FileVault is a security feature designed to prevent unauthorized access to the data on Mac’s startup disk. However, it can occasionally interfere with your macOS update, as it may apply encryption to your updated OS. You'd better disable FileVault before update macOS.

Step 1: Click the Apple logo > System Preference > Security & Privacy > FileVault

Step 2: Click the lock button at the lower-left corner, then enter an administrator name and password.

Step 3: Click Turn Off FileVault
