MacOS Big Sur

Apple has released a second Release Candidate for macOS Big Sur 11.0.1 to Mac users involved in the Big Sur beta testing programs.

The second release candidate build of 20B28 is perhaps likely to match the final shipping version of macOS Big Sur, which is scheduled to debut to the general public on November 12.

MacOS Big Sur 11 includes a newly overhauled visual interface with brighter UI elements, new icons, more white space, a revamped Dock appearance, a refreshed menu bar, amongst a variety of other smaller visual changes. Additionally, macOS Big Sur includes newly updated system sounds.

MacOS Big Sur also includes some new features, like bringing Control Center to the Mac. Additionally, Big Sur includes an overhauled Notification Center, new Safari features like customization of the start page and instant foreign language translation of web pages, new Messages features including in-line replies and mentions along with the ability to pin messages, along with various other smaller features and changes to the Mac operating system.

How to Download MacOS Big Sur 11.0.1 Release Candidate 2

As usual, backup the Mac with Time Machine before installing any system software updates.

  1. Pull down the  Apple menu, then select “System Preferences”
  2. Choose “Software Update”
  3. Select to update ‘macOS Big Sur 11.0.1 Release Candidate 2’

macOS Big Sur RC 2

Installing macOS Big Sur 11.0.1 RC 2 will require the Mac to reboot.

While macOS Big Sur is officially set to launch on November 12, users who can’t wait are still able to install the macOS Big Sur public beta now if they wish to. Note that beta system software is less stable than final versions, and thus is not recommended for anyone aside from advanced users.

If you’re interested in running macOS Big Sur, make sure you have a Big Sur compatible Mac.

Naturally, the just announced first generation of Apple Silicon Macs will all ship with macOS Big Sur pre-installed. The M1 equipped Macs will be able to run not only Mac apps, but also iPhone and iPad apps too, a feature that is not available for Intel architecture. It remains too be seen which build of macOS Big Sur ships with those new M1 Macs, but it’s conceivable that it will match the RC 2 candidate released today.

    There’s a problem with installing Big Sur RC2 on T2 Macs.

    You get an error that says “An error occurred installing macOS. You can try again to complete the installation.”

    But trying again fails, no matter how many times you try. It’s a problem with bridgeOS and the T2 chip.

    “The bridgeOS update doesn’t satisfy the given minimum version requirement.”

    Apparently you can fix it with this command:

    sudo nvram IASUCatalogURL=

    Then install the macOS Big Sur RC2, then when finished return to the command line and run:

    sudo nvram -d IASUCatalogURL

    Annoying. How do these kind of errors slip through the cracks? Shouldn’t this have been caught in testing and QA? Sigh.

    Found this solution on this site:

      The installer isn’t very robust and doesn’t handle glitches well. When my mac mini rebooted during installation, the system kept getting booted into the recovery partition in a loop. I had to hold down the Alt key and choose the installer in order to finish the installation. After installation, cmd-R no longer brings up the recovery partition or internet recovery, the system merely powers off automatically

    My Mac software update message went from “MacOS Big Sur 11.0.1 Beta” to “MacOS Big Sur 11.0.1”.

    does Big Sur have that screen saver that reflects the day like Mojave does?
