Part 1. Get MacOS Catalina DMG Via Direct Download Link

Many people prefer the direct download link of macOS Catalina as it is more flexible. You can unpack the DMG file and make a bootable Catalina installer USB, which can be used to install macOS on other computers. However, it is not easy to find the direct download link because Apple wants you to upgrade from Mac App Store. Fortunately, there are a few good websites that host the direct download link of macOS Catalina DMG. After that, you can burn the macOS dmg to USB to make it bootable for installation.

Tips: After downloading macOS Catalina .dmg file, it is time to make a macOS bootable USB from it. For this purpose, you can give a try on UUByte DMG Editor, one of the most popular software to create a Catalina USB installer on both Windows PC and Mac.

Part 2. Download macOS Catalina From Mac App Store

Apple always recommends its users downloading macOS install file from Mac App Store for security reasons. It is safe and easy. But the actual downloaded file is not an dmg file. Instead, it is an app called Install macOS Catalina, which is used to make the upgrade from current macOS to Catalina. For a clean install, it is better to download the dmg file and make an installer USB.

Note: Make sure to back up your Mac prior to installing macOS Catalina.

Step 1: Go to Mac App Store and search macOS Catalina. Then hit on 'Get' to download page.

Step 2: Doing this will open System Preferences followed by the section of Software Update, where you will find MacOS Catalina ready to download. Hit the option saying 'Upgrade Now' and download MacOS Catalina on your Mac.

Step 3: Next, macOS Catalina upgrade will ask for system reboot. Complete the process and install macOS Catalina on that computer.

Downloading macOS Catalina Install app works fine on my of newly devices but it could be problems for old Macs even it is officially supported by Catalina. If this is the case, then you have to patch the OS and install Catalina again. However, you need find a third-party app to do the dirty work. We will talk about this in Part 3.

Part 3. Download macOS Catalina 10.15 Installer with macOS Catalina Patcher

Although it may appear easy to try out the conventional approach of downloading macOS update in Software Update, there are a few known issues on old Macs shipped in 2013 or earlier, meaning the download progress can not be completed successfully. That's why macOS Catalina Patcher tool comes into help. This patching tool makes the job even simpler for installing macOS Catalina on unsupported Mac models.

However, the file size of these updates differs depending on the Mac device you are using. That means the downloaded update might not necessarily be the full installer version. For instance, if you wish to keep the installer file as archive for further application, or use it to generate bootable flash drive, this file size won't be sufficient.

Fortunately, with macOS Catalina Patcher tool, you can simply download the entire update of macOS setup from Apple's servers. Let's check out the stepwise instructions of how to use this software tool to download the macOS Catalina DMG.

Step 1: Download a copy of macOS Catalina Patcher from this link.

Step 2: After downloading and attempting to install, an error notification will be prompted. It is due to the unavailability of developer verification credential for macOS. Now, go to System Preferences -> Security & Privacy. Then find the button saying 'Open Anyway' to let the app run.

Step 3: Open macOS Catalina Patcher app and from the main menu, navigate to Options to uncheck the box saying 'Auto-apply Post Install Patches'. As you are done with the previous step and move to the screen as in the link below, hit Download a Copy.

Step 4: The following screen will notify the file size of macOS Catalina you are to download. The resolution is around 7GB and after the download, it will automatically get stored in the Downloads folder. Then hit Continue to initiate the process of download.

Step 5: The download time of the file will depend upon the internet connection and its speed. So, you might have to wait for some while for the process to complete. Eventually, the entire macOS Catalina setup file will be available on your device.

Closing Words

Well, that is all for the day. Hopefully, the above methods were helpful in guiding you on how to download macOS Catalina for both supported and unsupported Macs. When the download is finished, the next step is to burn the DMG file to USB. Then boot macOS from USB and starts the installation wizard.

It does not matter whether you use macOS or Windows 10. It’s just a matter of time until your device will refuse to start, which could happen for many reasons, including (and not limited to) file corruption, hardware failure, and buggy update. If the unexpected happens with an Apple computer, you can use a macOS bootable USB with the installation media to repair it.

This is one of the main reasons you should consider making a macOS bootable USB when your device is working properly. However, if none of your devices (MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro, or Mac Mini) aren’t working when you need them the most, then you can use a PC to rescue your Apple device. You can use a Windows 10, Windows 8.1, or Windows 7 device to quickly create a USB bootable installation media to reinstall macOS Catalina or Big Sur on your Mac.

In this guide, you’ll learn the steps to create a macOS Catalina bootable USB installation on Windows 10, which you can use to reinstall or upgrade the Apple OS.

Requirements

Before proceeding, you’ll need the following:

• Broken Mac computer running macOS (version 10.12, 11, or later).
• A trial copy of the TransMac software.
• One high-quality USB flash drive with 16GB of storage.
• Copy of macOS (DMG file).

Create macOS bootable USB installation media

To create a bootable USB drive with macOS, use these steps:

1. Download and install TransMac on the Windows 10 device.

   Quick note: This is a paid software, but it gives you a 15-day trial, which is more than enough time. (If this works for you and you want to support the developer, you can purchase the full version.)

2. Connect the USB flash drive. (If you have any data on the flash drive, remember to make a backup, as everything on it will be erased.)

3. Right-click the TransMac app and select the Run as administrator option.

4. Click the Run button. (If you’re using the trial version, wait 15 seconds.)

5. Right-click the USB flash drive, select the Format Disk for Mac option from the left navigation pane.

   Quick note: You want to do this before creating the bootable media because there is a good chance that the drive was formatted using a Windows device. If this is the case, the chances are that it’s using an MBR partition, and the USB drive needs a GPT partition to work on a Mac.

6. Click the Yes button to format the drive on the warning message.

7. Confirm a name for the drive. For example, “macOS bootable USB.”

8. Click the OK button.

9. Click the Yes button.

10. Click the OK button.

11. Right-click the USB flash drive and select the Restore with Disk Image option from the left navigation pane.

12. Click the Yes button to confirm the erase of the USB flash drive data.

13. Click the browse button on the right.

14. Select the .dmg file with the macOS installation files.

15. Click the Open button.

16. Click the OK button.

17. Click the Yes button.

Once you complete the steps, you can now insert the USB flash drive on your Mac computer to install, reinstall, or upgrade the operating system to the latest macOS version, which can be Sierra, Catalina, Big Sur, or higher.

Create a GPT partition on USB flash drive

If the USB flash drive is not working with TransMac, it could still be a partition problem. In this case, you may need to redo the entire process again. However, this time you should use the following steps to use the Diskpart command-line utility on Windows 10 to create the appropriate GPT partition, and then follow the above instructions.

5. Type the select disk command followed the number assigned for the USB flash drive (for example, select disk 4), and press Enter.

6. Enter the clean command and press Enter.

7. Type the convert GPT command and press Enter.

8. Enter the create partition primary command and press Enter to complete the process.

How To Create A Catalina Install Usb

Once you formatted the USB flash drive with a GPT partition, you can use the instructions mentioned above to use TransMac to create a bootable media, but this time skip steps No. 5 through 10 and continue on step 11.

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 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 Mac repair app. 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.

How to Fix Common Download Errors for macOS Catalina

Download Full Catalina Installer App Store

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:

1. Go to the Apple Server status website and check if the macOS Software Update‘s button is green. If not, then there’s probably some issues with the website, so you might need to try upgrading some other time.
2. If the macOS Software Update is green, but you’re still having download problems, check your internet connection. Consider switching to a wired internet connection if possible.
3. If the download is stuck for a long time, cancel it by clicking the X button.
4. 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 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:

1. Go to the Apple menu > System Preferences > Date & Time.
2. Tick off Set Date and Time Automatically.
3. If the option is already checked, uncheck it then reboot your Mac.
4. Go back to the Date and Time panel and check the option again.
5. Next, try re-installing macOS Catalina.

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:

1. Go to the Applications folder and look for the installer package for macOS Catalina. It is usually named Install macOS.
2. Right-click on the file and select Show Package Contents.
3. Click on Contents > SharedSupport.
4. Delete the Installlnfo.plist inside the folder.
5. Type in your admin password to confirm the action.
6. Click on the installer to run it again.

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:

1. Boot your Mac into Safe Mode by holding down the Shift key until you see the Apple logo.
2. 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.

2. Press Power + Command + R keys to bring up the macOS Utilities screen .
3. Click Reinstall macOS.
4. Select Disk Utility > Erase HDD.
5. Install the macOS Catalina from here.
