On November 12, 2020, Apple released the next version of the Mac operating system (macOS). It’s name is macOS Big Sur. Like all major operating system upgrades, it’s prone to have some significant bugs and/or will make some of your older applications incompatible, so please hold off on installing this major upgrade for a while. If you’re a customer and you subscribe to my remote monitoring, maintenance and support service (RMMS), you don’t need to worry about accidentally installing macOS Big Sur since I’m able to remotely block this major upgrade from being installed on your Mac.
I’m not the only one who recommends holding off on installing macOS Big Sur. Check out Tidbits’ article titled, Big Sur Is Here, but We Suggest You Say “No Sir” for Now. This article provides a good overview of the problems reported by early adopters of macOS Big Sur. It also highlights many of the changes introduced by BigSur. Are you ready for the learning curve?
If you’re a subscriber of my RMMS service and you try to install macOS Big Sur, you will see a notification like the one below. This image indicates that I’m blocking the installation of macOS Big Sur. My remote management tools will also remove the macOS Big Sur installer from your Mac. If you have a compelling reason to install macOS Big Sur or you’re doing it on a spare Mac, please contact me so I can unblock your installation.
