After this operation, you can go to update your macOS to see whether the installation can complete successfully. If the issue persists, you should try the next solution.

Fix 3: Free up Disk Space for the macOS Installation

Usually, a macOS installer can take up about 5GB of disk space on your Mac. But during the macOS installation process, the installer needs more space to unpack the related files and folder. This extra space is about 15GB. Thus, the minimum free space you need to prepare for a macOS installation is 20GB.

Is there enough free space on your Mac? You can have a check.

You can click the Apple Menu and then go to About This Mac > Storage to check how much free disk space on your Mac.

After accessing Apple’s official download center, you can switch to the macOS section and then select a suitable one to download.

Fix 5: Reset PRAM/NVRAM

PRAM or NVRAM saves some certain settings like sound volume, display resolution, startup disk selection, time zone, and recent kernel panic information. If you can’t install your macOS successfully, you can reset PRAM/NVRAM to have a try.

It is very easy to do this job. You can just shut down or force shut down your Mac (select one method according to your situation). After that, you need to press the Power button and immediately press and hold the Option, Command, P, and R keys together. About 20 seconds later, your Mac should restart. Then, you can re-update your Mac to see whether it can finish successfully.

3. Select the startup disk you want to fix and then click First Aid.

macOS Could Not Be Installed on Your Computer FAQ

A new version of macOS is always exciting. But it can quickly become frustrating if, instead of being presented with a brand new Mac, ready to use, you see an error message like “macOS could not be installed on your computer.” Fortunately, you can do lots of things to fix the problem, so let’s get started.

Before you try to install a new version of macOS

It’s essential that before you perform any major upgrade, say from Catalina to Big Sur, that you backup your Mac. One of the steps described below involves a complete reinstall of the operating system, resulting in erasing data from your drive. It’s best to do the backup using Time Machine, as you can then use Recovery Mode to restore your Mac from the backup. But if you don’t want to use Time Machine, create a bootable clone of your startup disk using a tool like SuperDuper or Carbon Copy Cloner.

Macos Could Not Be Installed

Why does “macOS could not be installed on your computer” appear?

There are several reasons you might see this error message. Here are some of the most common.

• Your Mac doesn’t support the version of macOS you’re trying to install
• There was a problem downloading the installer
• You don’t have enough space to install a new version of macOS
• There’s a problem with the disk on your Mac
• A piece of software like a launch agent or launch daemon is interfering with the upgrade

Before you try to fix the error

Check if your Mac is compatible with the version of macOS you’re trying to install. The best way to do that is to launch the App Store app, search for the macOS version you’re trying to install, and scroll down the Compatibility section. You should see a message that says, “works on this Mac.” Alternatively, go to Apple’s website support pages and search for the minimum system requirements. You might need to reboot in Safe mode, see below, to check because if you do a normal restart, your Mac may immediately relaunch the installer.

How to fix “macOS could not be installed on your computer”

Mac Os Cannot Be Installed

1.Restart your Mac in Safe mode

Safe mode disables startup items, launch agents, and everything else except the bare minimum macOS needs to function. Restart your Mac from the Apple menu or by holding down the power button, and press Shift until you see the Apple logo.

2. Try running the installer again while in Safe mode

If the problem were that launch agents or daemons were interfering with the upgrade, Safe mode would fix that. If it works, you should restart your Mac normally after the installation and remove any launch agents and daemons you don’t need.

The simplest way to remove launch agents is to use CleanMyMac X.

Here’s how:

1. Download, install and launch CleanMyMac X.
2. Choose Optimization from the sidebar on the left.
3. Select View all items.
4. Check the box next to Launch Agents
5. Press Run.

3. Free up space

You’ll need up to 20GB of free space on your main drive to download and install an update to macOS. If you don’t have that much free space, it’s time to clear out the junk and free up space. I’ve found that the quickest and easiest way to do that is to use a popular app CleanMyMac X by MacPaw. It can free up tons of gigabytes of space with a couple of clicks.

Install CleanMyMac X, then launch it — download free edition here.

1. Choose Smart Scan from the sidebar.
2. Press Scan.
3. When it’s finished, press Run to delete files immediately or Review Details to see what it has found.

4. Reset the NVRAM

The NVRAM on your Mac stores data even after your Mac shuts down or restarts, unlike regular RAM, which is flushed every time you restart. NVRAM persists, thanks to a small amount of power supplied by your Mac’s internal battery. Resetting NVRAM rarely has any effect, but it can do in some situations, and as it won’t do any harm, it’s worth trying. It’s quite tricky to do, so that you might need some help.

Restart your Mac while holding the Command + Option (Alt) + P + R keys and wait until you hear a startup chime. It may take a little longer than normal to restart twice, but the NVRAM will have reset once it's done.

5. Try the combo updater

If you can restart in Safe mode and quit the installer, try downloading the combo updater from Apple’s website. The combo updater contains all the files necessary to install macOS on all Macs, whereas the version downloaded from the App Store only has the files for your specific Mac. It may be that the combo updater works, where the Mac App Store version doesn’t.

6. Install in Recovery Mode

This is the last resort if nothing else works.

1. Restart your Mac while holding Command + R until you see the Apple logo.
2. When you see the macOS Utilities window, you have two choices. You can either restore your Mac from a Time Machine backup if you have one, which will take you back to where you were before you started. Or you can Reinstall macOS.
3. Choose the option you want.
4. If you chose Reinstall macOS, wait for your Mac to restart, then go to System Preferences > Software Update and update your Mac to the latest available version.

There are a number of things you can do to fix your Mac when you see the message: “macOS could not be installed on your computer.” If the problem is that you don’t have enough space, you can use CleanMyMac X to get rid of files you don’t need. Otherwise, go through the above steps one at a time until you’re able to install a new version or update to macOS.
