This Tuesday, November 10, Apple is expected to unveil new MacBooks running the latest version of MacOS, called Big Sur. These new Macs will likely be powered by Apple's own ARM-based chips for the first time.
Follow Apple's event live on YouTube from 19 p.m. local time:
MacOS Big Sur was revealed at Apple's annual conference, WWDC, last June. This new operating system presents major updates for the Safari web browser and the Maps and Messages applications. MacOS Big Sur is available now in public beta, and will be released in the final version free to all users in the fall. Note that you will first need to ensure that your Mac is compatible with the new operating system, here is the list of machines eligible for the Big Sur update:
- MacBook 2015 and newer
- MacBook Air 2013 and newer
- MacBook Pro Late 2013 and newer
- Mac mini 2014 and newer
- iMac 2014 and newer
- iMac Pro 2017 and newer
- Mac Pro 2013 and newer
To determine the version of your Mac, you will need to click on the icon in the navigation bar and then select the About this Mac option.
A public beta close to the final version
In general, public betas are still buggy: some apps won't work, there will likely be random reboots and crashes, and your battery life will likely take a hit. But now that we are getting closer to the final public version of the operating system, this fall, the public beta should also be closer to the final product. If you want to give it a try, we still recommend installing it on a spare device if you have one, instead of your primary Mac. The safest option is to wait for macOS Big Sur to be released publicly.
