What's the difference between this installer and one on astah* official site?
astah* for Mac OS X has implements below and it looks more like Mac OS X application compared to zip-file installer for non-windows users we currently provide on our official site.
- Menu bar is shown at the top of the screen
- 512 x 512 Application icon and document icon that work for Cover Flow (in Mac OS X Leopard or later)

Notes
EMF export/copy functionalities do not work in Mac OS X. Also layouts of buttons may not appear like Mac application on some dialogs and some functionalities may be ineffective if you only have one pointing device like one-button mouse.

Thank you.
