Creating a Time Machine Backup

Before upgrading to macOS Catalina, it is crucial to create a Time Machine backup. The reason for the backup is a safety measure for when you find your Mac to be incompatible with the Catalina OS, which means you can erase the upgrade and restore it using the backup you created.

Creating a backup whether upgrading or downgrading your Mac is not only a good idea, but also imperative. Unless you would not mind losing everything, we highly recommend creating a Time Machine backup before upgrading to macOS Catalina. Without the backup, it would take a lot of time to restore your system to its previous OS. You would have to download each program, plug-in, and driver once more.

Follow these steps to format an external hard drive for macOS:

Start Disk Utility, which you can find by navigating to Applications > Utilities > Disk Utility.
Choose the hard drive device and then click on Erase (if initiated, the process is irreversible)
Choose a name for your drive (e.g., My Backup) and select the format: Mac OS Extended (Journaled), then click on Erase.

Follow these steps to create a Time Machine backup drive:

Start Time Machine and click on Select Disk.
Connect a drive (reformatted or empty).
Select the drive you have just connected (e.g., My Backup) and click on Use Disk.
Click on the Backup taskbar icon and then select Backup Now.
