… I followed the instructions and all the packages d/l'd ok, got to the point of "installing" and just SAT THERE.
…
The installer creates a folder named BBDownloads in the root of the /Users/(user name). If this folder cannot be created, the Installer will freeze as described.
If you want the installer files to be downloaded anywhere else, this is easy but not intuitive. Here's how: Create a folder named
BBDownloads in whatever folder on whatever disk you like. Specify the path to the folder that contains
BBDownloads in the lower left corner of the Installer but do not include it in the path. The Installer will find the new BBDownloads folder, download the files to it, then run them when downloaded.
I have tested this in many locations on my Mac.
