How to fix the error cannot install macOS on the computer (1)

Before getting into the detailed fix, here are some of the most common reasons why macOS can’t complete the installation:

Path /System/Installation/Packages/ OSInstall.mpkg is missing or corrupted
Not enough free space on Mac
Error in macOS installer file
Problems with your Mac’s boot drive
Incompatible hardware
Whatever the cause of the macOS installation error, you can usually fix it yourself in one of the ways below.

If you can’t complete the macOS installation, you may find your computer stuck in a loop where the installer reopens every time you restart your computer. Follow the quick steps below to get out of that loop and protect your data before you fix the error.

Solutions for “can’t install MacOS Monterey” issues

Step 1. Start your Mac in Safe Mode

Safe Mode on Mac prevents various programs from launching at startup, including the macOS installer. Starting your Mac in Safe Mode helps you get rid of any boot loops and prevents troublesome programs from running in the background.

To boot into Safe Mode on an Intel-based computer, restart your Mac and hold down the Shift key while powering on. Release the key when you see the Apple logo or hear the startup sound and you’ll see “Safe Boot” in the menu bar on the login screen.

On a computer with Apple’s M1 chip, turn off your Mac and then press and hold the power button until the boot options screen appears. From here, select Startup Disk, hold down the Shift key then click the Continue in Safe Mode option.

Step 2. Create a new backup using Time Machine

It’s important to back up the data on your Mac  before installing a major macOS update. These updates edit core files in the operating system, so if something goes wrong you may need to completely wipe your Mac to fix it.

Connect an external drive and back up your Mac using Time Machine. Time Machine is the simplest way to protect all data in incremental backups. This allows you to restore data from specific dates instead of just keeping the latest version of everything.

Step 3. Check Mac Compatibility in the App Store

Before you start with installation troubleshooting, you need to make sure that the latest version of macOS is compatible with your Mac. Go to Apple’s support website and click the link for the version of macOS you want to install to see the hardware requirements. Click the Apple icon in the menu bar and choose About This Mac to compare those claims with your Mac.

If your Mac isn’t compatible, that macOS version upgrade won’t be able to install. This could be the first sign that it’s time to replace your Mac.

What to do when macOS installation can’t be completed

Once you’ve backed up your Mac and made sure it’s compatible with the latest version of macOS, it’s time to try the installation fixes below. 

Since there are many potential causes of macOS installation errors, one of the solutions below should be able to fix the problem. Let’s start with the fastest and easiest way to save you time.

Restart your Mac and try the installation again

Sometimes, all you need to do to fix a macOS error is restart your Mac and try again. Open the Apple menu and select Restart from the drop-down menu. If your Mac is unresponsive, press and hold the power button to turn it off.

However, do not do this while the installation is in progress, as doing so may damage files in the operating system.

Set your Mac to the correct date and time

It’s possible that the date or time on your Mac is showing up wrong. When this is the case, it can lead to connection problems with Apple’s servers, which can be the reason for the error when installing macOS.

Open System Preferences and go to Date & Time to modify it. Click Padlock and enter the administrator password, then select Set date and time automatically .

Make enough free space to install macOS

A macOS installer typically takes up about 4-5GB of space on a Mac. But to complete the macOS installation, the computer actually needs about 20GB of free storage space.

This is because the macOS installer needs more space to unzip files and folders. Without that extra space, the installer has nowhere to go and can’t complete the installation on your Mac.

Open the Apple menu and go to About This Mac > Storage menu to see how much free space is on your Mac. Click  Manage Storage to see what’s using the most space and then figure out how to free up more storage on your Mac .

Download a fresh copy of the macOS installer

The macOS installer on your Mac may have somehow become corrupted. You should try deleting the existing installer and downloading a new one instead.

Most older macOS installers are available directly from Apple’s support website, which provides the full hybrid installer, rather than a smaller version available through System Preferences or the App Store. However, you may need to download the installer from the App Store for newer versions like macOS Monterey.

Reset PRAM and NVRAM

PRAM and NVRAM are where various settings and options on your Mac are stored, like screen brightness, audio volume, and screen resolution. Errors with PRAM or NVRAM can explain why macOS can’t be installed on the computer.

It’s relatively easy to reset the PRAM or NVRAM settings on a Mac, and it won’t erase any personal data currently on the computer. To do so, restart your Mac and hold Option + Cmd + P + R while powering on.

Keep holding all those keys until you see the second Apple logo or hear the second boot sound, at which point the PRAM or NVRAM reset will complete.

Run First Aid on the boot drive 

After trying the above, still can’t complete the macOS installation? This can be caused by a fragmentation or drive permissions error on the boot drive. It’s fairly easy to fix most of these types of errors using the Disk Utility application, which comes pre-installed on macOS.

Open Disk Utility from the Utilities folder in Applications. Select your Mac’s startup disk in the sidebar, commonly called Macintosh HD, then click First Aid. When you run First Aid, Disk Utility will scan the drive for errors and repair whatever it finds.

If you can’t access Disk Utility normally, boot into macOS Recovery mode as shown below and try running First Aid again.

Use macOS Recovery to reinstall macOS

If macOS still won’t install properly, you may need to reinstall the entire operating system. This can be done using macOS Recovery mode on a Mac.

The process of booting into MacOS Recovery will vary depending on whether your Mac has an Intel or Apple processor.

On a Mac with an Intel chipset, restart the Mac and hold down the Option + Cmd + R keyboard shortcut simultaneously while powering on. Release this key combination when you see the Apple logo or hear the startup sound, then the MacOS Utilities window will appear.

On a Mac with an Apple chipset, turn it off then press and hold the power button until the boot options screen appears. Click the Options option and click Continue

Once you have entered macOS Recovery mode, click Reinstall macOS to install the latest version of macOS. This can take a while because your Mac needs to download new software first.

Erase Mac and restore from backup

The ultimate troubleshooting solution to any software-related problem is to erase the startup disk and reinstall macOS from scratch. With the new version of macOS on your computer, you can restore all of your Mac data from a Time Machine backup.

If you don’t back up your Mac before erasing the startup disk, you’ll lose all of your data including your photos, music, files, and everything else.

As you can see, there are many reasons why you cannot install macOS on your computer. However, through the above instructions of FPT Shop, we hope that you have been able to fix this problem.
