Shockwave Player has not yet been ported to run natively on the new Intel-based Macintosh computers and currently only runs in Rosetta emulation mode. To install and use Shockwave Player on an Intel-basedMacintosh, you will need to run the browser in Rosetta emulation mode. Follow the instructions below to launch your browser in Rosetta emulation mode.

Launching a Browser in Rosetta Emulation Mode
Applications like both Safari and Firefox default to running in native mode on the new Intel-based Macs and therefore you must follow a few simple steps to instead have then run in Rosetta emulation mode:

1. Quit out of the browser.
2. Go to your Applications folder and control-click on the browser application bundle.
3. In the context menu that appears select Get Info.
4. Under the General heading of the Info dialog select “Open using Rosetta“.
5. Close the Info dialog box.

After completing the above steps the browser will now run in Rosetta emulation mode thus allowing you to install and use the Shockwave Player.
