Big Sur 11.0 Beta 6 Download Error

[DCohen726]

Is anybody else getting a download error when grabbing Developer Beta 6 from Beta 5? Funny enough this doesn’t happen until after it downloaded. Security settings are high. I ran first aid. But the error message still pops up on my 2020 MBP

Edit: Finally fixed for me as I got a much bigger file size download. Such an odd error to have.

I had that problem. At the third attempt the download size increased significantly and installed (a long process with 3 reboots). I thought it wouldn't work but at the end everything is working OK.

This happened to me, it said the update was about 3.2GB and I tried downloading it three times but every time it downloaded and then after it completed it would say "Download failed". However, I've just noticed if after doing check for update I click 'More Info' then in there I see another option that is 11GB and an install button for that, so I've clicked that and now it's downloading 11.24GB... hopefully that will fix it.

In short, try clicking the More Info button when it shows the update.

Same happened for me, just retried a few times then worked fine,
