Revisions in 20 revisions had Nehalem/ Westmere architecture Intel Xeon processors. It was replaced on April 4, 2007, by a dual quad-core Xeon Clovertown model, then on January 8, 2008, by a dual quad-core Xeon Harpertown model.

Introduced in August 2006, the first-generation Mac Pro had two dual-core Xeon Woodcrest processors and a rectangular tower case carried over from the Power Mac G5. It is one of four desktop computers in the current Macintosh lineup, sitting above the Mac Mini and iMac and Mac Studio.

A recommendation would therefore move up to 10.11 El Capitan. Update: Since the release of High Sierra it has to be presumed that also Yosemite is now some kind of abandonware. In terms of performance, security and support, whether from Apple or third party developers, Snow Leopard is not that good of a choice, especially if this machine is going to be used on the net. But there are now certain downsides to be considered for this approach. "If I buy Snow Leopard?" As stated above Snow Leopard should work. If it had Sierra previously installed and WiFi was working you are good to go with it. That might be the only real deal breaker for Sierra on this hardware. A 2009 MacBook Pro is listed there as a supported machine, in principle.īut be sure to verify your WiFi card is supported before you go that route. See this Sierrapatch to help you with that.

(Which would be self-evident if the terminology used in the OP's question is accurate.) But Sierra can be installed and works for many more Macs than Apple allows.

But you need access to an ***Install.app that is usually downloaded via the AppStore. To install any version of OS X/macOS it is strictly speaking not necessary to provide or even have an AppleID. That translate into version numbers as anything from 10.5.7 (9J3050) to 10.11 (and with caveats: also 10.12) can be installed. This 2009 MacBook Pro should be able to boot anything from Leopard, Snow Leopard, Yosemite to Sierra.
