I've tried several times to download/install Big Sur and it always fails. I have over 110gb available on my 2014 MacPro Retina.

Anyone have good suggestions for upgrading my MacPro Retina 2014 to Big Sur? Keeps failing... Got lots of space available, not sure what else is needed.


MacBook Pro 13″, macOS 10.15

If you are having issue, try initiating the the download from the Safari browser:


Big Sur macOS 11.6

if you still have an issue— try from a Safeboot environment
