How to Fix macOS Big Sur Problems?

Apple has developed a stable and functional operating system. But in some cases, even on the new generation Mac, problems, and crashes with system applications can occur. In this article, we will describe the most common macOS Big Sur problems. This version of macOS is one users are more likely to have problems with.

Let’s take a look at popular bugs and fix them.

How to Fix macOS Big Sur Installation Issues?

First, we need to deal with macOS Big Sur problems that occur at the part of installing the OS. Often, many people can’t even download it and install it correctly. Even on modern laptops and computers that fit all the system requirements.

One of the first reasons for macOS Big Sur issues is the congestion and performance of Apple servers. This regularly happens when a major update is released, when many Mac owners at once try to install the latest version of macOS. The servers fail and stopped working.

Initially, it is worth going to the page with the status of Apple servers and making sure that the light next to the macOS Software Update option is green. If the yellow circle opposite is lit, then Apple is aware of the issues and is probably already fixing them. All you have to do is wait for it to happen.

How to Fix the Mac’s Long Boot Time Problem?

Another macOS Big Sur issue is the long boot time and installation of the Mac.

More often than not, it occurs for two reasons:

  • High load on the servers due to a large influx of people wanting to download the update.
  • Low speed of your Internet connection.

In the first case, there is nothing you can do, and you will have to wait until the download wave subsides to speed up the OS download process.

In the second case, you need to check your network connection. To complete that, you can visit the SpeedTest website and check what maximum download speed is available for your provider and tariff plan. If it does not match the download speed of the macOS image, then it is worth checking to see if someone is straining your connection. Perhaps some other object is downloading. Stop all extraneous tasks and try downloading the update again.

How to Fix the Gateway Timed Out Error?

The Gateway Timed Out error often occurs during macOS upgrades. When this error occurs, the system won’t boot. There is currently no specific solution to this problem, but users who have encountered it say that booting in safe mode helps.

Follow these steps to boot your Mac in Safe Mode:

  1. Turn off the device.
  2. Start it up again.
  3. During startup, hold down the Shift and don’t release it until the OS has fully booted.

After that, you’re required to re-request the update through the system settings. The problem should not occur again.

How to Fix macOS Hanging During Installation?

Sometimes macOS hangs right during installation or during the setup phase. Inexperienced users get scared and don’t know what to do because there is no access to the system.

In this situation, creating new hard drive partitions and reinstalling can help.

Follow a few steps:

  1. Turn off the computer.
  2. Turn it on and press Command + Shift + R to enter system restore mode.
  3. Open the command line by clicking on the Utilities menu and selecting the appropriate option.
  4. Enter the diskutil list command to display a list of available hard disk partitions.

  1. Find the one you want to clean and remember its name for the next command.
  2. After that, enter diskutil eraseVolume JHFS + drive the path to the desired partition (e.g. /dev/disk0s4).
  3. Then merge the empty disks into one partition with the diskutil mergePartitions JHFS command + name of the new disk + path to the first partition + path to the second partition (e.g. MacintoshDisk disk2s4 disk2s6).

After that, you can try to install the system again to a clean partition. There should be no problems during the installation.


That’s all for now. Now you know how to get rid of most of the macOS Big Sur issues. But in any case, it is recommended to do a complete reinstallation of the OS once a year to keep it running fast and stable enough. This is the easiest method to keep even an old Mac up and running. After reinstalling, it’s better not to restore your data from a backup, but to download it from the cloud. In that way, you’ll reduce the chances of macOS Big Sur bugs even more.
