I tried to install Big Sur but I don't have enough space
My macbook air had around 20GB of free space. I tried to download the Big Sur update which was way lighter (it said 12GB). The update started, but after a while, a screen popped up telling me I didn't have enough space to install the update, and it stopped. I then checked the storage option and it said I only had 10GB left. I can't seem to find where this "update leftovers" are, but I would really like to delete them to gain back some space.
Thank you.
MacBook Air 13″, macOS 10.15
