macos big sur stuck at 12.44GB installation

hey everyone, i've been trying to download big sur but it stays stuck at 12.44GB and refuses to move, although my storage keeps dropping. this is about the 10th time i've tried to install big sur, and nothing it happening. for context, i'm still on mojave. should i just reinstall mojave in recovery mode so i don't have to deal with this? i lost all of my storage trying to install big sur. i would love for it to actually upgrade though. :(

if there is any way to delete big sur files that are already installed, please someone let me know!

MacBook Air 13″, macOS 10.14

Boot into Safe Mode and try the upgrade and its associated download there.

Safe Mode rebuilds caches, deletes temporary files, and temporarily disables some of the more pernicious add-on apps.

You’re also ~completely out of free storage.

App and system upgrades tend to require more storage.

And require room to unpack the download.

I’d always expect the 120 GB configuration to require management of storage,

i'm out of free storage because big sur tried to reinstall multiple times, it was ****! putting it into safe mode literally gained me 50GB because it erased the files that attempted to install.

are these files going to reinstall once i exit safe mode? i do not want them...

Attempting to install Big Sur several time without first checking the Application Folder for an incomplete Application called Install Big Sur is going to eat space and maybe even fail to work at all. Especially on a very small 128 GB internal drive.

Apple clearly states " If upgrading from macOS Sierra or later, your Mac needs 35.5GB of available storage to upgrade."
