Want to upgrade Mac OS from Mojave to Big Sur. Told that I have inadequate space. Need 14.95 GB. Is there a solution?

How to free up storage space on your Mac - Apple Support

From: How to upgrade to macOS Big Sur - Apple Support

"If upgrading from macOS Sierra or later, your Mac

needs 35.5GB of available storage to upgrade. If upgrading from an

earlier release, your Mac needs 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."
