You may not benefit from this if you have always been a Macintosh user, but this is a compromise you need to make if you want to update your machine to Big Sur.

The codes, interface, and other factors that come with making a Macintosh app universal needs to be stored in your device. A universal app is an app that can run on both any computer or mobile device, even if the device is not from Apple. Chances are if your computer has slowed down after downloading Big Sur, then you are probably running low on memory (RAM) and available storage.īig Sur requires big storage space from your computer because of the many changes that come with it. MacOS Big Sur requires an astonishing 46.01 GB of storage space on your Mac – 12.18 GB just for the update file and the remaining 34.83 GB is used up to be able to deploy and perform the new MacOS installation.

The download itself is already several gigabytes in size, so many people have had to wait the whole day for the whole system update to finish downloading. Mac users can download macOS Big Sur through the Mac App Store. MacOS developers promised that this major system update would be big – and they weren't joking.
