My Macbook Air wants to update to MacOS Big Sur, but when I try to complete the install, it tells me it is too big for the available GB I have.

Then you will need more space.

"If upgrading from macOS Sierra or later, macOS Big Sur requires 35.5GB of available storage to

upgrade. If upgrading from an earlier release, macOS Big Sur requires

up to 44.5GB of available storage. To upgrade from OS X Mountain Lion,

first upgrade to OS X El Capitan, then upgrade to macOS Big Sur."
