In order to get ArchiCAD 6.5 to run in classic environment (emulation) on OS 10 using a WIBU key, one must copy the necessary system files from the AC 8/8.1 cd-rom
Archicad 8.1:Support:ArchiCAD 6.5
into the ArchiCAD 6.5 folder.
Run WIBU 4.00 (or similar) Installer-> Delete Kernel Extension. This removes :system:library:extensions:wkClassicNotSeize.kext
Now you can run ArchiCAD 6.5 on OS X.
However, if Classic Environment is running in the background (even after ArchiCAD 6.5 or some other Classic application like PlotFlow is run), ArchiCAD 8.1 will crash repeatedly with WIBU-Key not found. Test this via:
Save CTRL-S (hit this key combination many times) and you will induce the crash.
The workaround: close Classic Environment in the Force Quit menu via option+Cmd+esc
