Hi Scott, thanks for your reply.
Yeah I tried the disabling of security, but the ".app" file is still grayed out. Maybe no data was placed into the file in the first place. I don't know.

I might have to "borrow" my Son's PC.

Cheers.

Hi all. I'm new here. I downloaded the Mac version of the game, and it automatically extracted the zip file. The instructions say to run the hydrosim.app file.

This file has zero kb and does not show as an ".app" file, ie, it's grayed out.

Is anyone able to help please?

Thanks.
