While it is filled with lots of exciting features and improvements, the new version of macOS recently released by Apple, Big Sur, has its drawbacks. The primary one is that it has a heavy capacity, which slows down the system’s performance. Due to this, many people downgraded their Macbook devices to the preceding version, Catalina. By doing this, they forego all the new features of the latest macOS for the more reliable performance of the former.
If you are looking to downgrade your macOS from Big Sur to Catalina, this article provides you with a step-by-step guide on how to go about it without losing your precious data.
1. Do a Backup of Your Data
The first step for downgrading from Big Sur to Catalina is to save and backup your data on the current macOS. You can do this in several ways. Firstly, you can copy your data onto an external drive. You can also use a cloud storage facility such as OneDrive. Finally, you can use the Time Machine tool to back up your data or files.
2. Delete the Wayward macOS From Your System
This is the most crucial part of the downgrading process. However, if you follow the steps below, you can do it without any hassle.
