I guess a better question would be, "How does a warranty work in general?" I bought a mac mini off of eBay a little while ago, which included a full, 1 year warranty. The thing is, it didn't come with a receipt or anything that talked about a warranty. It did come with the original box, manual, and everything else though. Would I still be able to benefit from the warranty since mini itself is covered by it, and since I still have the original box, or is something else needed to prove it? I've never really dealt with warranties so I wasn't sure how it normally worked. Thanks in advance for any info .
