You may occasionally visit a webpage that requires a plug-in that’s not already on your computer. Here are some tips for getting the correct plug-in.
Check the webpage for a recommendation
Websites often recommend the appropriate plug-in. If the website doesn’t recommend one, contact the owner of the website.
Check to see what processor you have
Open System Profiler, and find the processor name under Hardware in the Info window.
Your processor will be either PowerPC or Intel. If you have an Intel processor, get the Universal version of the plug-in.
Use Rosetta to improve compatibility
If your have an Intel-based Mac computer, but the only available version of a plug-in is for PowerPC-based Mac computers, you can use Safari with Rosetta to improve compatibility. For more information, see:
To see a list of your installed plug-ins, in Safari choose Help > Installed Plug-ins.
