Thanks mamba-negra.

I see your point. Most people who use Poser on a Mac will know this stuff already. But as the PC installation instructions I provided would apparently lead to disastrous consequences on a Mac, I did not want to be responsible for someone following them blindly and trashing their Runtime folder.

I can recognise how my present advice could be seen as either anxiety producing, or patronising, depending on the users level of experience. But I would rather be safe than sorry. I am hampered in providing really good advice by the fact that I don't know what the f..k I am talking about when it comes to a Mac install. All I can do is to pass on what I have learned in this thread, with as little distortion as possible. If I can find a link to a tutorial I will include that link, if it seems like a good tutorial I might even scrap my advice and just point them to the tutorial. I was hoping that someone might know of such a tutorial, but no one has suggested one so far.
