Hi,
I think that the right-click issue with single-button Mac mice needs more attention. Even as an experienced Mac user, it took me a couple of hours to pick my way through manuals, forum postings and so on to arrive at a solution (below). For newcomers to PS (and perhaps to Macs as well), this is an unneccessary and frustrating obstacle to getting started, as you cannot begin to interact with objects or NPCs without contextual menus. To my mind, telling people to get a two-button mouse is not helpful - everything else in the Mac world works with a single mouse button and always has.
I suggest that:
1. Future Mac versions of the application should automatically recognize Ctrl+Left click as being equivalent to Right click in all circumstances, as is the case with all well-behaved Mac applications.
2. In the meantime, I suggest a sticky in this forum that deals specifically with the issue, so that new users are discomfited as little as possible.
In case it helps anyone , my solution was:
1. Open Options
2. Select Controls > Mouse
3. In the line Selection > ContextMenu, perform a Ctrl+Left click on the "set" button
4. Click Save.
Now you can talk to Harnquist
