I haven’t noticed any significant speed issues on my recent model Mac. My experience installing and running Big Sur has been good.

I set aside plenty of time to install it, and recommend you do the same-expect it to take hours. I ensured my backup was current, signed up for the beta, and ran through some troubleshooting steps before the Big Sur beta was offered.

They’re designed for the specs of the current year’s Mac, which means it will almost always run slower on your Mac than the previous version. I’m really enjoying it so far.Įach operating system update adds features and requires more system resources than the previous version, including memory and storage space. Safari has received a speed boost and extensions, and other apps have been updated, too.

I just installed the public beta of macOS Big Sur (update: the public version is now available to download).
