Part 1: Preparations for Installing macOS Catalina 10.15


Before you start the installation process, there are certain things that you need to take care of. For instance, you should check if your Mac is compatible with macOS Catalina or it has enough free space on it or not.

  1. Check that your Mac is compatible with macOS Catalina

First things first – make sure that your Mac would support the new OS or not. Ideally, if your system runs on macOS Mojave (except 2010-12 Mac Pros), then it would be compatible with macOS 10.15 too. Here are all the devices that would support the new macOS Catalina:

  • MacBook Air 2012 or newer models
  • MacBook Pro 2012 or newer models
  • MacBook 2015 or newer models
  • Mac Mini 2012 or newer models
  • Mac Pro 2013 or newer models
  • iMac 2012 or newer models
  • iMac Pro (all models)
  1. Clean up your computer

You mustn’t have a lot of unwanted space on your Mac before upgrade to macOS Catalina. Simply follow these suggestions to clean up your system quickly:

  • Uninstall all the old apps that you no longer need
  • Get rid of any file that is not important
  • Empty Trash from your Mac
  • Delete Safari History or any other browser data
  • Sign-out or offload apps with too much data

There are times when users end up losing their data while upgrading to a new operating system. If you don’t want to encounter a similar situation, then consider taking a backup of your data beforehand. To do this, you can either manually move your files somewhere else or use Time Machine. Simply attach an external hard drive to your Mac and launch Time Machine on it. From here, you can take an extensive backup of your Mac to the attached media.

  1. Know your Apple ID

If you wish to do a macOS Catalina upgrade, then you might be asked your Apple ID for verification. Therefore, you should know your Apple ID and password in advance. You can go to the iCloud application on your Mac to check the same. Furthermore, you can visit the Account Details option from here to know more about the linked Apple account.

  1. Check the free storage on your Mac

To successfully install macOS Catalina, you need a 4 GB RAM on your system and at least 12.5 GB free space on the hard drive. Although, macOS Yosemite users would need at least 18.5 GB of free space instead. You can go to Finder > About This Mac > Storage section to see how much empty space is there on your Mac. If it is packed with too much data, then you can delete any unwanted content from its hard drive.

Part 2: How to Upgrade to macOS Catalina 10.15

Catalina

If you are already using a stable version of macOS, then you can just upgrade to the latest macOS Catalina easily. To do this, you can go to the official website of Apple, visit the Mac’s App Store, or go to its Software Update settings. Once you have taken care of all the above-mentioned prerequisites, simply follow these steps to learn how to update to macOS Catalina.

  1. If your system is running on macOS High Sierra, Sierra, or El Capitan, then you can just go to the App Store and look for Catalina. Read the features and just install macOS Catalina from here.
  2. Alternatively, you can also go to the official website of Apple and click on the “Upgrade Now” button to start the process.
  1. Though, the most recommended solution to do macOS Catalina upgrade is by visiting its Software Update settings. From the Finder, go to the About This Mac feature.

Part 3: How to Clean Install macOS Catalina 10.15


Apart from just upgrading macOS on their system, some users choose to perform a clean install instead. The macOS Catalina upgrade would retain the user data, apps, third-party app data, and so on. If your Mac has inherited some problems, then an upgrade won’t be able to fix it. In this case, you can perform a clean installation of macOS Catalina 10.15 from scratch.

Kindly note that a fresh installation of macOS would remove all the existing data, apps, or saved settings from your system. Therefore, you should know these things in advance:

  • The entire process would take at least 1-2 hours.
  • You should have a USB drive or an external hard disk with at least 16 GB of free storage.
  • If you don’t want to lose your data, then take its extensive backup beforehand.

The process to clean install macOS Catalina can be divided into two parts – firstly we will create a bootable media for it and later would use the same to install macOS.

Step 1: Create a Bootable Installer with Terminal

Unlike a macOS Catalina upgrade, the clean install process would be a bit tedious. Once you have taken a backup of your data, follow these steps to download the macOS Catalina installer and create a bootable media.

  1. Go to the App Store on your Mac and look for Catalina or macOS 10.15 from here. Once the dedicated profile for macOS Catalina would be opened, click on the “Get” button to save the macOS Catalina installer.
  1. When the installer is downloaded completely, quit the application from the menu bar or by pressing the Command + Q keys. This will prevent the autorun from the macOS Catalina installer.
  2. Now, go to Finder > Applications > Utilities and launch the Terminal application. Just enter the “Sudo” command followed by a space to get things started. Also, make sure that the USB drive/hard disk is connected to your system.
  1. Afterward, launch the Applications window from the Finder and go to its menu to view package contents. You can also browse to Applications > Utilities > Content > Resources.
  2. Here, you can view a “createinstallmedia” file. Just drag this file and drop it on the Terminal instead.
  3. Great! Now, just go to the Terminal window and enter the command /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/XYZ. Here, XYZ would be replaced by the name of the bootable media (your pen drive).
  4. That’s it! Now you need to press the Enter key and verify your Apple ID and password to make the attached USB drive a bootable media.

Step 2: Clean Install macOS Catalina 10.15

After when the bootable media is created, you can take its assistance to clean install macOS Catalina on your system. For this, you can just boot your Mac in the Recovery Mode and install the OS copy on it.

  1. Restart your Mac and while it boots, press and hold the Command + R keys at the same time. Keep holding them until your Mac boots in the recovery mode.
  1. Once Mac would boot in the Recovery Mode, it will display the available macOS Utilities. Just click on the Disk Utility option from here to launch the application.
  2. Now, select your Macintosh HD from the sidebar and click on the “Erase” button on the right. Select the file system and partition scheme for the hard drive and click on the “Erase” button again.
  1. Wait for a while as all the existing data on your Mac’s hard disk would be erased. When the system would be restarted in the recovery mode afterward, you can choose to reinstall macOS.
  1. Hold the Option key just to be safe that you get the feature to select a source to install macOS on your system. Just select the attached bootable drive that you have just created from here and start the installation process.

  • Your data can be overwritten by something else in the process.
  • If there is no adequate space on your system, then some of your files would have been lost in the process.
