berdel,

For now, you will indeed need Silverlight for Netflix on your Mac. As rkaufmann87 suggested, you should always get any plugin directly from the manufacturer and keep it updated frequently for security reasons.

The good news is that Netflix is currently working on doing away with the Silverlight dependency. Within a few months we should all be able to cellebrate when Netflix releases a new version that uses modern HTML5 instead of Silverlight, and will run on all standards-complient browsers such as Safari, Chrome, and Firefox.
