chris / everyone...
you can also use apple's 'Property List Editor' to add the new setting . . . it can be installed as a part of the developer tools: found under ./Applications/Installers/ (or ./Applications/Utilities/Installers - i forget)
it's a graphical user interface for the above procedure for people not keen with messing in the terminal . . .
simply add the 'DisableCrossPlatformMountingFeatures' setting as a "New Sibling" of the 'InputOuput' entry. set it to 'Boolean' and then 'Yes'.
bear in mind that anybody using archiCAD in a cross platform (PC<->mac) environment will have to specify any external file paths manually when opening a PC created file with mac archiCAD . . .
also - anybody using chris' terminal method above should only copy and paste as he suggests
if you are using the same US version of archiCAD as chris
. otherwise, replace the file names with the correct localisation and version!
