think it provided the flexibility of other systems. They gave it an 8 out of 10. Sound on Sound, an audio recording technology magazine, thought it was a "great machine" for musicians and audio engineers. Architosh, an online architectural design magazine focused on mac technology, would have scored it a perfect five except for a few issues with software compatibility and the high price for FB-DIMM memory. Cylinder (2013) Apple Senior Vice President of Marketing Phil Schiller presented a "sneak peek" of the completely redesigned Mac Pro during the 2013 Worldwide Developers Conference keynote. The video revealed an overhauled case design, a polished reflective aluminum cylinder built around a central thermal dissipation core and vented by a single fan, which pulls air from under the case, through the core, and out the top of the case. The only finish available is black, though a single red-finished unit was produced with Product Red. Apple states that the cylindrical Mac Pro achieves twice the performance of the last model. The model was assembled in Austin, Texas, by Apple's supplier Flextronics on a highly automated line. The announcement six months prior to release was unusual for Apple, which typically announces products when they are ready for market. It was released on December 19, 2013. The cylindrical thermal core was unable to adapt to changing hardware trends and left the Mac Pro without updates for over three years, leading Apple to make a rare admission of a product's failure in April 2017 when it detailed the issues surrounding the design and promised a totally redesigned Mac Pro. The design of the cylindrical Mac Pro has received mixed reviews, which has been described as appearing like a "small black trash can", rice cooker, or R2-D2 or Darth Vader's helmet. On September 18, 2018, the Mac Pro surpassed the Macintosh Plus's production life record for an unchanged Mac model, with the Plus having remained on sale unchanged for 1,734 days. It was discontinued on December 10, 2019, after being on sale unchanged for a record 2,182 days. Hardware The redesigned Mac Pro takes up less than one-eighth the volume of the immediately previous model, being shorter at , thinner at and lighter at . It supports one central processing unit (CPU) (up to a 12-core Xeon E5 CPU), four 1866 MHz DDR3 slots, dual AMD FirePro D series GPUs (up to D700 with 6 GB VRAM
