startup disk

I bought iCloud Storage to update my MacBook to macOS Big Sur but it still says that my startup disk is too full and that I need 19 GB to update, I don't have anything saved on my laptop and I have deleted all cache files, how can I update my MacBook?


MacBook Pro 13″, macOS 10.15

Free up space, you want to have 15-20 % free storage at all times.


You could simple try a safe boot  https://support.apple.com/en-us/HT201262

to clear cache and try your update from there.

Try something like OmniDiskSweeper for a GUI to get a good look at itemized file size and location:
