Macos Beta

Apple has released the next version of macOS 11 named Big Sur at WWDC 2020. The looks and visual changes have been amazing. If you are excited and want to install it then take a look at this ultimate guide to download macOS Big Sur 11.5 developer beta 1 on your Mac.

The Mac OS X Public Beta (internally code named 'Kodiak') was the first publicly available version of Apple Computer 's Mac OS X (now named macOS) operating system to feature the Aqua user interface. It was released to the public on September 13, 2000 for US$29.95. MacOS Big Sur is now available to the public, but there is still a developer beta line that needs testing before Apple launches new iterations to the public. Apple provides a beta version of its macOS releases to developers so that they can test their apps against it and prepare for the release to Mac owners.

Take a backup of Mac before updating to macOS Big Sur

Even before installing regular updates, we suggest taking a backup of the macOS device. And this is a developer beta – most likely having bugs and other issues! So, we stress even more that you backup your Mac before installing macOS Big Sur. To do this:

  1. Plug in an external HDD or SSD to your Mac
  2. You will see a window asking you to use the drive to back up with Time Machine. Check the box for Encrypt Backup Disk. After this click on Use as Backup Disk.
  3. If you do not see the above window, click on the Apple icon, and select System Preferences. Click on Time Machine.
  4. Click on Select Backup Disk, and choose your drive.
  5. Finally, check the box for Encrypt Backups (recommended) and click on Use Disk.
  6. Check the box for Show Time Machine in the menu bar. Next, click on it from the top menu bar, and select Backup Now.
