The "most powerful Mac ever" is coming just in time as promised and just in time for the holiday season. Mac Pro users, companies and firms will be delighted with the specs that this PC has to offer.

"We have begun manufacturing the Mac Pro in Austin. It's the most powerful Mac ever," tweeted Apple CEO, Tim Cook.

First unveiled during the World Developers Conference (WDC) earlier in June, the Mac Pro system has caught everyone in surprise with its shape and killer specs.

The new generation Mac Pro's system comes in a cylindrical aluminum body. The cylindrical design stands in 1/8th of a standard tower unit, says Tech News World. The cylinder aluminum body weighs 11 pounds and measures 9.9 inches tall, 6.6 inches in diameter.

The top of the line computer is on sale in time for the holiday season and is available at a starting price of $2,999 or $3,999 depending on the selected configurations. The next generation Mac Pro comes with the Mac OS X Mavericks operating system.

The new system can sport 4-, 6-, 8- or 12-core Intel Xeon processors allowing up to 3.9 GHz in Turbo Boost speeds. It also holds two AMD FirePro GPUs folding the current generation Mac Pro's performance in eight.

According to Bloomberg Business Week, the new Mac Pro has twice the speed of the existing model - thanks to its Intel Xeon processors. It has also greatly reduced power consumption by up to 70 percent due to its smaller size.

The buzz on the new Mac Pro tower is not only about its specs but also about its origin. Apple's flagship device has been known to be 'Made in China' and in other parts of Asia.

This time around, the tech giant's CEO has pushed for a 'Made in USA' Mac Pro. In fact, the 'most powerful Mac ever' is actually assembled in the US - with 'assembling' meaning 'not just putting together.' In fact, the new Mac Pro reportedly has "Designed in Cupertino, Assembled in the USA" etched at the bottom.

"We don't want to just assemble the Mac Pro here, we want to make the whole thing here. This is a big deal," Cook said in the report.
