Free up space
How do I free up space on my MacBook Air for Big Sur? It requires a lot of space. I have a 128Gb storage MacBook Air. There is 31.76Gb in other, what is this? There is 29.33Gb in documents, but there are no documents there, they are all on iCloud and all are very very minimal size. I have no music, films or large applications. How can I not install the latest MacOS?
Please help, loosing my mind
Many thanks
Andy
