After three years without a substantial update and several months of teasing and promoting, Apple has finally announced that tomorrow it will begin selling the newly designed and more powerful Mac Pro it first showed off at WWDC back in June. (Full press release below.)

The road was certainly not rapid between update cycles with two years of nary a word on whether or not the Mac Pro line had any life left in it and a full year of teasing and promoting the 2013 model being released tomorrow. Let’s take a look at the Mac Pro saga that led to today’s debut…

Tim Cook offered the first tease of the Mac Pro way back in December 2012 during an appearance on NBC’s now-cancelled Rock Center with Brian Williams. Apple’s CEO described the company’s investment in bringing production of what we would later learn to be the new Mac Pro into the United States:

Months later in May, Mr. Cook described the unreleased American-assembled Mac line during an unrelated Senate hearing as being built in Texas with components and equipment sourced from Illinois, Florida, Kentucky, and Michigan.

It was June 10th during WWDC that Apple surprised us all with its theatric reveal of the professional desktop line with a Hollywood-style trailer showcasing the 2013 Mac Pro.

SVP of Marketing Phil Schiller revealed the all new design of the Mac Pro as well as other details like 4K display support and Thunderbolt 2. Schiller famously followed up the trailer presentation by teasingly saying “Apple can’t innovate, my ass.” What Schiller did not express at the time was pricing and availability short of later this year.

Fast forward to October 22 during Apple’s Fall Event for the iPad Air and iPad mini with Retina display. Here the company revealed the professional desktop’s $2,999 and $3,999 price tag for quad-core and 6-core base models, respectively. However, the company did not reveal the 2013 Mac Pro launch date, opting instead to simply commit to a vague December launch.

Apple also continued the marketing campaign for the unreleased computer offering a highly produced video look at the Mac Pro assembly process.

A Jony Ive and Marc Newson designed (PRODUCT)RED 2013 Mac Pro was listed and sold at auction for $977,000 between October and November (and once believed to be purchased by Tony, Fadell, former head of Apple’s iPod division and Nest founder and CEO).

Interestingly, select journalists began receiving marketing posters for the highly anticipated Mac Pro around the same time showing Apple’s continuos effort in drumming up interest and anticipation for the next-generation Macintosh.

Now the real excitement unfolds with the all new Mac Pro shipping to the handful of Mac fans and professionals lucky enough to pick one up.

Our own Jordan Kahn interviewed extreme sports photographer Luca Gilman (pictured above) who was included in among select few professionals Apple chose to test drive the 2013 Mac Pro ahead of its December debut.

Expect more great stories like Gilman’s to come as the brand new Mac Pro finally enters the market for the first tomorrow.
