Not knowing what you're current Internet speed is, I can't say for certain you'll really notice any difference for ordinary web surfing. I have a slow DSL and the only reason for getting a faster speed would be for downloading and uploading files. At around 1Mbps down and .38 up, pages load quite fast, so I don't think I'd notice the difference for ordinary loading of web pages. But going from my current DSL to Verizon fiber would make a significant difference for larger downloads. Right now a 1GB file takes over two hours; with 15/5 that would take far less, just minutes I suppose.
But to answer your initial question, the Mac won't have any problem with the increased speed.
