Personal system
Any modern Macintosh with OS X 10.5 will work to access this system. All Mac laptops come configured with an iSight camera which is supported by AccessGrid 3.0 on OS X 10.5.
Configuration
There is a bug in the AccessGrid 3.0 Beta configuration which need to be fixed before you can use the Mac client.
http://lists.mcs.anl.gov/pipermail/ag-tech/2009-June/021032.html
The failure to launch is a known bug in that beta. You can work around it by editing ~/.AccessGrid3/Config/preferences, and changing this line:
multicast = True (or maybe False)
to
multicast = 0
or you can use 1 if you do have multicast available.
