Apple has released macOS 11 Big Sur, but we advise delaying upgrades to production Macs thanks to significant behind-the-scenes changes.

Apple has unveiled its first Apple silicon Macs: a new MacBook Air, MacBook Pro, and Mac mini. The new M1 chip gives them impressive performance and remarkable battery life, but Apple made few other notable changes.

macOS 11 Big Sur is right around the corner, but we recommend holding off until Apple, Mac developers, and the Mac community can smooth the rough edges.

Apple has opened public betas of some of its next-generation operating systems, but remember that these aren’t for daily use. Only install on hardware that you can dedicate to testing.

Apple unveiled macOS 11.0 Big Sur during the WWDC keynote, showing off overhauls of Messages and Maps, while improving Safari, Photos, and other apps. Mail was conspicuously absent for now.

Described as being the biggest update to macOS since OS X, macOS Big Sur features streamlined design, more customizable controls, privacy enhancements, and increased interoperability with iPadOS and iOS. X hasn’t marked the spot for several years, but we’re now in Spinal Tap territory: it’s macOS 11.0 Big Sur, for those who are keeping score.

The rumors finally came true. At the WWDC keynote, Apple announced that the Mac would be transitioning to custom-designed Apple processors along the lines of those that power the iPad Pro. The first such Mac should be available by the end of this year, with the full transition taking about two years.
