I have a Late 2015 iMac with 32 Gig of RAM. I am attempting to download macOS Big Sur Beta 5 and the Software Update stops at preparing macOS Big Sur Beta 5 (about 2/3). It has been stuck for about two hours. Is there anything that can be done to complete the download and install the beta?

Same here (mac book pro 2019), i'm trying to download the update for two months (crashes around 90+ %).
i've tried all commands, but no luck - the download is starting but never finishes (i have more than 200GB free on my disk), i can start it all over again but it's all the same.

On my iMac 5K (same network), download and installed it the first time, no issues.

Apple ???
