MacOS Big Sur update

Since performing the update it will not complete the install and is frozen. I have tried to hard reset and I have even let it go completely flat but nothing is working. I get the same thing, it gets to about 95% (the loading bar) then just stops and freezes. Please help

iPad, iOS 10

It wasn't already installed. It said last update was in 2020. I'm not sure of the version I installed as it won't let me in now to look.
Whatever the latest one I guess?

Where was that said in original question ??


Since it appears this may Actually be an upGRADE , which is much different than an upDATE - suggest shutdown the computer by whatever means required including Power Button. Disconnect all external devices. Connect to charger. Restart the computer in >>>> Safe Mode <<<<<.


Safe Mode will do a Repair Disk, clear cache files and only load Apple Software, extension and Fonts so loads slowly - Normal. It can take up to 10 or more minutes to eventually start and it may or may not allow the upGrade process to complete - hopefully successfully.

This implies Big Sur is already installed. What version of Big Sur is already installed ?? What updated version of Big Sur is being attempted to install ??
