Apple’s latest macOS, Catalina, has just been released to the public last October 7, 2019 and you can now install it on your Mac, as long as your device meets the hardware requirements. First revealed during the WWDC 2019 conference in San Jose, California, macOS Catalina introduces some new exciting features and functionalities.
As we say goodbye to iTunes, macOS Catalina brings in new apps and features to the table, including Apple Music, Podcasts Books, and TV. Another major feature is Sidecar, which can turn your iPad into another display. For ordinary users, this means getting a secondary display for free. For developers, on the other hand, this secondary screen can be used as a drawing tablet using supported apps.
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:
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:
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.

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.
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.
How to Fix Common Download Errors for macOS Catalina
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:
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 Errors When Preparing for the Installation of macOS Catalina
Once you have successfully downloaded the installer to your device, the system then prepares your Mac for the installation process. There are users who encountered errors during this stage and came across the Error occurred preparing the installation. Try running the applicationagain message.
The first thing you need to do when you encounter this error is to reboot your Mac. You might need to restart your system a couple of times to deal with this problem. If the error doesn’t go away after rebooting, here are some steps you can try:
Check Your Mac’s System Date and Time.
An incorrect system time usually gets in the way of a lot of system processes, including updates. To make sure your Mac’s date and time are correct, follow the instructions below:
Re-Download the Installer.
If the step above did not work, you might have to delete the macOS Catalina installer on your Applications folder. Find the Install macOS file in the Applications folder and move it to the Trash. Empty the Trash and reboot. Once your Mac restarts, try downloading the installer and then run the install process again.
Delete the Installinfo.plist File.
If you encounter the Copy of install macOS application is damaged and cant be used to install macOS error during the preparation of the installation, the best workaround is to delete the installinfo.plist from the installer package, then try re-installing.
To delete the installinfo.plist file, check out the steps below:

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:
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.Download Mac Os Catalina For Windows
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:
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.

Apple's been busy, rolling out the new iPhone 11 and 11 Pro, iPads, its new Apple Arcade gaming service, Apple Watch Series 5 smartwatches and Apple TV Plus. And now, not missing a step, it's released Catalina, the latest verision of the MacOS.

With Catalina, Apple replaces the iTunes app with three separate apps: Apple Music, Apple Podcasts and Apple TV. Perhaps just as useful, the revision lets Mac users run iPad apps they can download through the Mac App Store and use an iPad as a second screen, much in the way you might use a monitor. And with Catalina, Mac users can now check out Apple Arcade.
If you can't wait to get your hands on Apple's new OS, here's how to download and install Catalina.

Check you can run Catalina
First, before you get started, check that you can install the new OS. Catalina's hardware requirements remain the same as for MacOS Mojave, the current version of the OS, so if you can run Mojave, you can run Catalina. Here are the Macs that meet the requirements:
To check which Mac you have, from the Apple menu, choose About This Mac. The Overview tab displays which Mac you have.
Before you install Catalina...
Before you download and install the MacOS update, ensure the move to Catalina goes as smoothly as possible.
Make a backup. Before you download and install any big MacOS update, have a good, current backup of the contents of your Mac's drive, in case something goes south during the installation or afterward and you need to revert back. You can either use the Mac's built-in Time Machine backup utility or grab a Mac backup app like Carbon Copy Cloner.
Know your Apple ID. If you're a Mac user, you probably have an Apple ID. If not, get one, because you'll most likely need it during the Catalina setup process and logging into iCloud.
Check your free storage space. The download is big -- around 6.5GB -- and Apple said you should probably have about 20GB of free storage space to install Catalina.
Update your apps. With Catalina, Apple is turning off support for 32-bit apps. What that means is, if you have an older app you still use -- say, Microsoft Office 11 for Mac -- check that you have a 64-bit version of the app before you move to Catalina. If not, you'll either have to find a replacement or stick with your current MacOS so you can keep using the software.
Ready? Download and install
After you've completed your preparations, you're ready to download and install Catalina.
1. Head to the Mac App Store, and in the left sidebar tap Updates. If Catalina is available, you should see the new OS listed. You can also search for 'Catalina' in the store if you don't see it. If that doesn't work, from the Apple menu, choose About This Mac and tap Software Update to see if it appears. If you still don't see it, Apple may be doing a staggered update, so be patient while it rolls out.
2. Tap the Update -- or Get -- button to download the update.
3. Step through the installation prompts to complete the installation.
