If you’ve been a PC user before switching to Mac, you know what a truly seamless experience updating macOS is compared to Windows.

What’s more, they are completely free!

Installation Of Macos Could Not Continue Download

Dec 18, 2017 Now I'm new to apple and MacOS products and such. I bought a MacBook Pro on eBay for cheap cause it is having the blinking folder icon problem. I thought I could fix it as I'm an expert when it comes to computers (windows computers, that is.) I know very little about macs but what I do know is that I could recover the os from command + R but the 'Reinstall Mac OS' option isn't working. Reinstall macOS. Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions. Follow these guidelines during installation: If the installer asks to unlock your disk, enter the password you use to log in to your Mac. If the installer doesn't see your disk, or it says that it can't.

Fix macOS issues with Setapp

From installation to performance monitoring, Setapp has 190+ apps that help you safely upgrade to a new macOS.

Here’s how to update OS on Mac at any time:

  1. Go to System Preferences ➙ Software Update

  2. If there’s a MacBook update available, click Update Now

In 95% of cases, that’s all you need to do to update Mac software. However, very rarely, you might also see an error saying that the macOS installation couldn’t be completed or macOS update could not be installed or something similar. And there are a few ways to fix that.

What To Do To Get A MacBook Update

When you start analyzing what gets your macOS Big Sur install stuck, the first thing to pay attention to is the version of your Mac. As new and more feature-rich macOS updates appear, they stop supporting older Macs that are simply not powerful enough.

Here are all the Mac models supported by macOS Big Sur:

  • iMac (2014 or newer)
  • iMac Pro (2017 or newer)
  • Mac Pro (2013 or newer)
  • Mac Mini (2014 or newer)
  • MacBook (2015 or newer)
  • MacBook Air (2013 or newer)
  • MacBook Pro (2013 or newer)

If you compare macOS Big Sur 11 system requirements to those of macOS Catalina, you’ll notice the latest version moved a year to two years ahead. So make sure you have a compatible Mac before trying to install an update.

Well, it’s technically possible to run Big Sur on even older Macs by installing a third-party patch, but this is not officially supported by Apple and is not generally recommended for the security of your Mac. Since macOS support usually lasts for more than five years on various Macs, it might be time to actually upgrade your setup — it’s going to serve you well.

Running a brand new Mac? Here are some more things to consider to make sure you never have your macOS update stuck again.

Check the system status at Apple

Being one of the largest tech companies in the world, Apple’s systems are very stable and rarely have a glitch. Still, fate might have it that you’ve tried to update Mac software exactly at the time when a server was undergoing maintenance.

To check that the Apple software update download problem is not on their end:

  1. Go to

  2. Look for macOS Software Update and see if it’s green

Make sure your WiFi network is up

If the problem is not with Apple’s network, it might be with yours. Having a volatile WiFi connection could easily be the reason behind the macOS installation couldn’t be completed error. Luckily, it’s easy to test:

  1. Visit and click Go to see your current internet speed

  2. Try switching to the Ethernet connection, if that’s an option

  3. Contact your internet provider for support

In case you still see your Apple software update downloading, maybe you should just give it some more time (e.g. a couple hours) and wait.

Restart the update and your Mac

Let’s say that a few hours have passed and your update doesn’t seem to be moving anywhere — just cancel the process if it’s downloading or restart your Mac, by holding the power button, if you find macOS update stuck in installation.

Update Mac software via App Store

It might come as a surprise for some, but Apple software update downloads are also available via Mac App Store. The only catch is that those updates have to be between major versions (e.g. Catalina ➙ Big Sur) and not minor releases of the same macOS.

So if you’re still running on Catalina:

  1. Open App Store on your Mac
  2. Type “Big Sur” in the search field
  3. Click Get

What if you need to get an incremental update? For example, macOS 10.15.3 to 10.15.4. You’re in luck, since Apple posts all its software versions on its website as well:

  1. Visit
  2. Click Download on any update that interests you
  3. Double-click the .dmg file from your Downloads folder to start the process

Set date and time to automatic

For one reason or another, you might have set your laptop to display custom time. Unfortunately, such a change might interfere with the MacBook update. To resolve this, try to set your time and date to be determined automatically:

  1. Go to System Preferences ➙ Date & Time

  2. Check the box next to “Set date and time automatically”

Go into Safe Mode

In some unique situations, you might have your Big Sur install stuck in black screen with no apparent ways out. Hold ⌘ + L to see the log of all activity and verify that no progress is being made. If not, it might be because some random processes are interfering with the proper installation, so you need to turn off your Mac and try to use it in Safe Mode.

Safe Mode starts up your Mac while blocking most of the external scripts, logs, or preferences, so nothing can get in the way of the system working properly.

To get your Mac in Safe Mode:

  1. Turn it off

  2. Press the power button while holding Shift

  3. Try to do the MacBook update once again

Reset NVRAM on your Mac

A more involved step beyond getting into Safe Mode is wiping your non-volatile random-access memory (NVRAM) clean. NVRAM is used to store certain settings and preferences while your Mac is turned off, which could make it difficult to update Mac software if a logging error has crept in somewhere there.

To wipe out NVRAM, restart your Mac and hold ⌘ + Option + P + R. Then try to initiate the update once again.

Reinstall macOS in Recovery Mode

If neither Safe Mode nor resetting NVRAM helps, you could try the most definitive solution — reinstalling macOS in Recovery Mode.

Unlike Safe Mode, Recovery Mode basically forces you to get a brand new version of the operating system, preferably deleting all the contents of your hard drive in the process (using Disk Utility) to ensure that errors like “macOS could not be installed on your computer” don’t appear again in the future.

To reinstall macOS in Recovery Mode:

  1. Hold ⌘ + R when you’re restarting your Mac to get the same macOS. For the newest version possible, use ⌘ + Option + R.

  2. Choose Reinstall macOS out of the options given

  3. Click Continue

  4. Go through the installation process

How to restore your Mac from backup

For active Mac users who haven’t done much in the realm of optimization for a while, it’s strongly suggested to delete all their hard drive contents during the reinstallation of macOS using Disk Utility. Naturally, no one wants to lose years of their data — that’s why frequent backups are so essential.

Get Backup Pro is by far the most complete backup solution available today. You can easily do straightforward backups, and the app will compress the size of the archive by up to 60%, or you can do backups incrementally, only updating the files that have changed since the last backup. Other options include cloning your whole volume to a new external drive, so you can have your Mac with you anywhere on the go, and synchronizing folders between Macs to always have the same access to critical information.

What’s more, with Get Backup Pro you can schedule all the processes to never forget to update your backups and never lose more than a few days (or even hours) of data.

How to keep your Mac optimized

What if the macOS update could not be installed because your Mac is simply too old? Don’t despair, you can still get a lot of the perks of having a brand new macOS by properly optimizing your Mac.

Prepare Mac for new macOS

Too much clutter and system junk can cause macOS installation problems. Get CleanMyMac X to optimize Mac before upgrading.
