Macs Running macOS Big Sur Will Install Software Updates Faster Than Before

Apple announced macOS 11 Big Sur during the company’s annual WWDC event last week and while there was time given to the release during the keynote, there were features that didn’t get attention.

We’re learning more and more about those features as developers take the update for a spin in its current beta form. One of the new features is the ability of macOS Big Sur to perform system updates more quickly than ever.

Updating macOS currently takes up to an hour depending on the Mac and the update being applied. But according to notes on Apple’s website and spotted by 9to5Mac, things will be improved in macOS Big Sur.

Once macOS Big Sur is installed, software updates begin in the background and complete faster than before — so it’s easier than ever to keep your Mac up to date and secure.

It’s thought that the update will now process all the required files ahead of a system restart, reducing the amount of time where the computer is unusable. It’s a similar process to that used on iPhone and iPad, allowing users to continue working while the update is prepared in the background.

A further note also mentions that a new security feature also improves the speed of updates, too.

macOS Big Sur introduces a cryptographically signed system volume that protects against malicious tampering. It also means that your Mac knows the exact layout of your system volume, allowing it to begin software updates in the background while you work.

While developers are already testing macOS Big Sur, a public beta is expected later this month. A final, public release will arrive in or around September, too.
