Clean Trash bins

Do you know when you delete something on your Mac, it still resides on it. Well, you might not know there are secret trash bins for each disk partition and external drive. And, undoubtedly, the files you delete are still somewhere in Mac taking some storage.

  1. Go to CleanMyMac X application
  2. Then select “Trash bins” from the cleanup section located on the left panel

Similarly, you can clean up the junk for iTunes and mail attachment following the same process. This will ensure that you are getting as much space as you could, and trust me you’ll be needing this.

Backup Your Mac

Backup your Mac, no matter what. Even if you have auto-backup on for every day, I would recommend to manually backup your Mac just before updating to the Big Sur. It is a big update, anything can go wrong, and losing all the data should be the last thing on your mind.

For backups, Mac has a special feature available known as “Time Machine“. You can set it up and start backing up your Mac now. However, there are plenty of other ways you can back up your Mac, but this is the most convenient I could get through.

Get macOS Big Sur

Now that you have prepared your Mac for the big update, it is time to get your hands dirty with beta macOS Big Sur. Head over to and download the new macOS whenever it is available.

Here is a quick tip: You can install the update on the main drive. However, I recommend not doing that as the update is relatively new and there is a chance that you might face compatibility issues with certain apps. Therefore, partition your main drive and install the Big Sur over there. This will keep your important files safe, while you can enjoy the new features of macOS.
