Check in Applications folder for an " Installer Big Sur " if it exists. If Yes, Drag and Drop to Trash and empty Trash.


macOS Big Sur is compatible with these computers


If upgrading from macOS Sierra or later, your Mac needs 35.5GB of available storage to upgrade. If upgrading from an earlier release, your Mac needs up to 44.5GB of available storage. To upgrade from OS X Mountain Lion, first upgrade to OS X El Capitan, then upgrade to macOS Big Sur.
