With the release of macOS Catalina 10.15, a lot of Mac users are enthusiastic to install the newest Mac operating system. Just like the previous versions of macOS, some were able to upgrade without a hitch, but several users encountered various issues during downloading and installation of the update.

Some users experienced slow downloading of the update, while others got error messages when installing Catalina, including:

Storage system verify or repair failed
This copy of the Install application can’t be verified. It may have been corrupted or tampered with during downloading.
An error occurred while preparing the installation. Try running again.
Copy of install macOS application is damaged and can’t be used to install macOS.
There is not enough free space on the selected volume.

This guide will give you a detailed rundown of the most common macOS Catalina installation and update errors encountered by Mac users when upgrading or installing macOS Catalina, along with the instructions on how to deal with these hiccups.

Why macOS Catalina Won’t Install

Various problems can occur during the installation of macOS Catalina. If the installation won’t start, seems to freeze midway , or never seems to complete, then it means that there must be something wrong somewhere.

The first main reason why users can’t install macOS Catalina is compatibility problem. If your Mac doesn’t support macOS Catalina, you won’t be able to proceed with the installation. You need a fairly recent Mac to be able to run macOS Catalina. Here are the Mac models that support the newest macOS:

MacBook (2015) and later
MacBook Air (2012) and later
MacBook Pro (2012) and later
Mac Mini (2012) and later
iMac (2012) and later
iMac Pro (2017) and later
Mac Pro (2013) and later

If your device is not on this list, then you’re sure to run into problems when installing Catalina.

Another thing you need to check before installation is your available storage space. You will need around 6.5 GB just to download the installer. Once you’ve downloaded it, the amount of space you will need during the installation depends on whether you’re doing a clean install or an upgrade.

A clean install will eat up around 20 GB of storage. On top of that, you have to make room for apps, user data, and user updates. An upgrade install, on the other hand, will only take up 6.5 GB of space for the installer, plus some installation files that the installer will copy to your startup drive.

If you’re tight on storage space, you should consider removing unneeded apps and files on your Mac. You can uninstall the apps one by one, and delete cache files and data using Outbyte MacRepair. Make sure you have at least 25 GB of free space to be able to install macOS Catalina successfully.

Aside from compatibility issues and insufficient storage, poor internet connection, incomplete or corrupted installation files, hard disk problems, and faulty software can also cause issues during the installation of macOS Catalina.

Installation Checklist for macOS Catalina

Before proceeding with the installation, it is necessary to spend some time ticking off the checklist below. These steps will not only prevent errors from happening, but also ensure that your data remains safe in case something goes wrong.

Back up your Mac, especially your iTunes media library since Catalina will no longer have iTunes.
Take note of the 32-bit apps on your Mac . You will need to update them to the 64-bit version after upgrading, or find an alternative for them.
Delete old Install macOS files from your Applications folder. These old macOS installation files may cause error during the upgrade.
Remove all external drives and accessories.
Plug in your Mac’s power adapter.
Connect to a stable Wi-Fi network.

Once you’ve completed these steps, you can now proceed with the upgrade.

How to Upgrade to macOS Catalina

The easiest way to download and install macOS Catalina is through the App Store on your Mac. Just open the App Store and search for macOS Catalina. Click the install button to start downloading, then click Continue.

You can also visit the macOS Catalina website and download the installer from there. The installer will be downloaded to the Applications folder on your Mac. Once downloaded, the installer will open by itself. Just follow the onscreen instructions to proceed with the installation. You might be asked to log in using your admin username and password during the process.

As long as your device is compatible with Catalina and you’ve followed the instructions, you’ll be able to successfully install the new macOS on your Mac. But if you encounter any error during the download or installation, refer to our guide below to sort out the issue.

Downloading the installer is the first step of the installation process. The installer takes up 6.5GB of storage, but you will need more space to be able to run the new macOS smoothly. If you have Automatic Updates enabled, the installer might already be downloaded on your device.

If the installer has not yet been downloaded, go to the Apple menu > System Preferences > Software Update to download Catalina.

If the downloading process gets stuck or is taking a long time to complete, here’s what you can do:

If the download is stuck for a long time, cancel it by clicking the X button.
Switch to a different DNS server and retry the download again.

It might take a few attempts for the downloading to be successful, especially in the early days of the release of the update.

How to Fix Catalina Installation Errors on Mac

After preparing your Mac, the system then proceeds to the installation process. There are different errors you might encounter at this stage, so you need to take note of the error message and at which stage it happened.

Here are some of the errors you may encounter during the installation process.

Stuck at Setting Up Screen

When you’ve been stuck with the Setting up your Mac message for several hours or you encounter the dreaded spinning wheel, the best way to deal with this is to restart your device. Press the power button to shut down your Mac, then press it again to reboot.

Storage Space Problems

If you failed to optimize your storage space before the installation, you might come across errors related to insufficient storage space. You might see the macOS Could not be installed, the target disk is too small message or the There is not enough free space on the selected volume error.

This happens because you do not have enough space on your Mac. Free up some storage first before proceeding with the installation. You might need around 20GB to 25GB of space for macOS Catalina to run efficiently on your Mac.

Network Access Error

If you see a Code=551 error anytime during the installation process, you need to check your network settings. This error happens to devices with overactive firewall or those installed with third-party security software, such as VPN and antivirus. If this happens, disable this software first before trying to reinstall macOS Catalina.

Installation Doesn’t Complete

Sometimes, your Mac gets stuck with the x minutes remaining screen during the installation. When you encounter this problem, click the X button to exit the installation process and check your console logs. It is possible that your user account is corrupted, preventing your system from completing the installation process.

The only way to deal with this is to create another admin user account and install macOS Catalina using that account.

Mac Fails to Start After Update

You might think that everything is over once you finish the installation process and your Mac restarts. But sometimes, errors can still happen even after the installation has been completed. Some users reported getting stuck with a black screen, while others encounter the spinning wheel during the restart following the update.

This error is usually caused by incompatible or corrupted kext files. Kext or Kernel Extension files are the drivers for macOS. To check whether kext files are causing the error, move all of them out of your Extensions folder before rebooting your Mac.

To move your kext files, follow the steps below:

Boot your Mac into Safe Mode by holding down the Shift key until you see the Apple logo.
Open Terminal under the Utilities folder, then copy-paste the following command:

mkdir ~/Extensions-Backup && sudo mv /Library/Extensions/* ~/Extensions-Backup/

Once done, restart your Mac in normal mode and see if it goes through.

If All Else Fails, Do a Fresh Install.

If you’re still having issues despite following the guide above, you may need to do a fresh install of macOS Catalina. To do this:

Shut down your Mac.
Press Power + Command + R keys to bring up the macOS Utilities screen .
Click Reinstall macOS.
Select Disk Utility > Erase HDD.
Install the macOS Catalina from here.

Remember that erasing your HDD will delete all of your files and settings, so make sure you have a backup before doing a fresh install. This should hopefully take care of common macOS Catalina installation problems.

Select the option that states, ‘Obtain an IP address automatically’.

Click OK to save the changes. BlueStacks is supposed to work now.
