  What is macOS Big Sur public beta?

The present version of the Mac operating system is macOS 10.15 Catalina. The next version is macOS 11, Big Sur. Apple creates a public beta version of Big Sur available for the public to try out, test against their favorite software, and report bugs to the company.

Though it is beta software, it could make problems on your Mac. You may face frequent freezes and crashes, or apps may not work.

Don’t make a count on it being stable enough to use all the time.

Should you install the macOS Big Sur public beta?

macOS 11 public beta 2

Don’t install the beta on a production Mac or any other Mac you based on and need to keep running. If it worries you that a beta flaw will prevent you from using your Mac, then don’t install it. Install it on a Mac that you feel as a secondary computer.

If you tried the beta, you can give Apple with valuable feedback and get a look at the latest features.

What should you do before installing it?

Do a backup. You can make use of Time Machine or whatever backup setup you already have. If You need a backup, you can revert it to in case you need to stop using the beta and want to restore your system.

 How to make a backup in your Mac

macOS 11 public beta 2

Before admitting the public beta, make a backup of your Mac. That’s why if you are not happy or something goes wrong and want to revert to macOS Catalina you can go right back to where you started.

Even though you did a backup every night, you must make sure double, triple times they cover you. So, now make a manual backup.

Here we will know how to di it with Time Machine. Even if you use something additional or different like super-duper be sure you manually start a backup now.

  1. Tap on the Time Machine icon in your menu bar.
  2. Press on backup now.
  3. Wait until the backup finish before proceeding

Tip: if you are not averse to the terminal if needed to jumpstart reversion, you can also make a bootable macOS Mojave installer.
