Hi all! I been having problems installing the new and latest MacOS Big Sur which for my laptop: quite old is Macbook Air Retina, 2018 with about 108 GB. I have a storage capacity left of around 25 GB and still needs to install another 12 GB and another about 20-30 GB to get the Big Sur. It beens so confusing. I have seen other question but the replies does not even help for example the teddy's one. I don't use Time Machine and by entering all of the commands in the terminal, doesn't work. So please help me. I want to install Big Sur Thanks A Lot for reading this Please help me solve this problem 🙏
