Add the steps involved:
Once the Install button has been hit you will be prompt with the following window.
If you have not backed up your information, please close/cancel this upgrade and return to it after you backup your data. This will restart your computer in 4-5 minutes and any unsaved data will be lost. It is advised you run this upgrade at the end of the day as it may take 30-40 minutes to complete. |
Once you are confident that your information is securely back up, click Install to begin the macOS Catalina Installation.
Your machine may ask you to log in and then begin to update again. This will not happen for every user. |
Once the macOS Catalina installation is complete, you will be able to log into the machine and begin using it.
After the installation there will be a shortcut folder on your desktop called "Relocated Items". This folder can be moved to the trash. |
