Well, This at least should be mentioned on the download page, with maybe also a quick note about where to find the install documentation.

Mac users are used to a very smooth install procedure: drag to the app directory, double-click to run.

I understand that this "as easy as possible" culture where the computer is supposed to adapt to the user - not the other way around - might not be universal, but here the impression is that it's deliberately obfuscated.

I'll try what the thread you linked suggests.
