Legacy versions of Vectorworks will not run properly on Leopard (OSX 10.5) or Snow Leopard (OSX 10.6). You may experience random crashing, instability or screen display issues, such as a hatch across most of the screen.
If you attempt to open an outdated version of Vectorworks or MiniCAD on the Mac OSX Leopard or Snow Leopard operating systems, you may get something that looks like this.
To use Vectorworks on OSX 10.5 or later, you will need to use Vectorworks 12.5.3 or newer.
