[AG-TECH] AGTk on MacOS

[Eric Olson]

Hi Charles,
You don't need to run the node setup wizard (runns.sh).  It is not 
currently needed for anything (unless it somehow helps debugging).

 From the launcher (runag.sh):
- The only button really needed is Main->VenueClient
- You may first want to run Configuration->Node Setup Wizard, but don't 
run it at the same time as the VenueClient.  Optionally, you can 
accomplish the same things that the node setup wizard does by using node 
management from the VenueClient menu: Preferences->Manage My Node...
- If you are using a multi-machine node, you can start a service manager 
from Services->Service Manager.

I have seen other people run the node service recently, although it's 
not needed (it would have been removed if we weren't trying to minimize 
unnecessary changes for the 2.4 release) -- can you tell me if you found 
this suggestion in the documentation somewhere, or if it's just not 
clear in the user interface (very likely)?

The error you're getting is that there is no audio and video after you 
connect.  I would suggest two things:
- Make sure you have audio and video services listed under 
Preferences->Manage My Node.  To send video, you should remove the 
VideoConsumer service and add the VideoService (which will "Produce" and 
"Consume" video).
- Evaluate your network and firewall.  If you don't have multicast 
networking. you'll need to use a bridge or the new AG Connector (still 
being tested, but works very well).  To use a bridge, you'll need to 
find a venue with bridges in it -- all venues in the Community Lobby are 
bridged.  Selecting Preferences->"Use Unicast" is all you need to do. 
If "Use Unicast" is greyed out, the current venue does not have a bridge.
