The Mac Pro 2013 has the dubious honor as the longest produced Macintosh, besting the Macintosh Plus produced from 1986 to 1990 without an upgrade. While most users (and Apple engineers) probably prefer moniker 'cylinder,' the trash can title stuck due to its obvious physical characteristics. Is there a need or demand for such a guide? I don't know, but here we are, and while the origins are jocular the rest of this guide is serious. The 2013 Mac Pro is a tale of hubris for Apple, as it over-promised and under-delivered, and is considerably less upgradeable than its predecessor. The Definitive Trash can Mac Pro 2013 upgrade guide started in jest on social media as the guide no one wanted, seeing as the Mac Pro 2013. To mark the first anniversary of my wildly successful blog post (garnering tens of thousands of views), The Definitive Classic Mac Pro (2006-2012) Upgrade Guide, I'm proud to announce a sequel.
