There are significant issues like performance, hardware issues, and driver compatibility that can push you to downgrade to a lower or medium Mac OS (from a more powerful OS version).
Many Mac OS users will ask one question. How do I revert to an older version Operating system? Well, there are a few steps involved.
Mac OS come in different versions (and this is according to the release date). For instance, you could be using Big Sur and want to downgrade it to Catalina or High Sierra to Sierra. Take note that it doesn’t matter which OS you are using. The downgrade process is similar in all the Mac OS.
This downgrade process can be straight forward if you have the correct guide. But, many factors should be considered before beginning the downgrade process.
Factors to consider before an upgrade:
There are three factors that you should not ignore.
- Processor speed
Here, we will look at everything you should know when downgrading the Mac OS to an earlier version.
What to Note – Before the downgrading process begins, you need to back up all your data. The downgrade will delete all data in the Mac.
There are crucial steps involved. Below are five steps that you need to follow acutely.
Before downgrading, you should erase your Mac’s hard drive. Erasing the hard drive not only leaves enough space for the downgrade. Erasing the hard drive helps get rid of program files and data from the previous OS. Read our guide on how to format a drive on Mac to understand how to complete the process.
Steps involved if you have a time Machine backup
- Make sure that your Mac is fully charged. If not, you should plug it in and continue.
- Restart the computer
- Press Command + R when the Mac is rebooting
- Click Disk Utility
- Select Startup Disk
- Click Erase. (choose the recommended format and continue)
- Enter your Apple ID and quit Disk Utility
- Restore your backup to the earlier Mac OS version from the time Machine backup. Click continue (the computer will search for all the available time Machine backups). When you see the specific backup, click continue.
Steps involved if you don’t have a time Machine backup
- Download the Mac OS installer from reliable internet sources like the App Store
- Create a bootable file from the already downloaded OS on an external drive
- Format your Mac and restore it to factory settings
- Restart your computer and press the command + R button to open Disk Utility
- Follow the prompted instructions. (Different OS have different steps to follow)
- Insert the bootable installer to continue
It’s important to always create backups on your computer to not only use it during the downgrade process. Time Machine backups can help you recover lost files, and it can also help you resolve OS-related issues with your Mac.
