Intensely graphic based. Shows you the default button through the pulsing. Platinum interface extended. You can set it up so only one window is live at a time. So as the window you click is growing to become live, the old program shrinks.
Icon has more pixels for the desktop image.
Buttons for resizing are no longer in separate areas. They are at the top - red, yellow and green. Trouble running certain applications should be diminished. Entire Mac interface was re-written. Dialog boxes drop out of title bar so that it is associated with the document that you are working with.
