1 - Is this an Upgrade and if so from what version of macOS ??

2 - How much Empty Space is available on this computer ?? What are the System Requirements ie: Empty Space Requirements specific to the Big Sur. Apple States Requiring 35.6 GB of Empty Space but suggest 50 GB

3 - By what method this this computer connected to the Internet ??

4 - Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation. The Built-in Security of Big Sur is all that is required.
