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.
Use plug-ins designed for your computer
Open System Profiler, and find the processor name under Hardware in the Info window.
Your processor will be either Intel or PowerPC. If you have an Intel processor, get the Intel or Universal version of the plug-in. If you have a PowerPC processor, you must use a PowerPC (PPC) or Universal plug-in.
Use Rosetta to improve compatibility
If you have an Intel-based Mac computer and you’re using Mac OS X v10.4 Tiger or Mac OS X v10.5 Leopard, you can use plug-ins designed for PowerPC-based Macs. To do so, you must first install Rosetta. For more information, see:
