Apple received criticism after an incremental upgrade to the Mac Pro line following the 2012 WWDC. The line received more default memory and increased processor speed but still used Intel's older Westmere-EP processors instead of the newer E5 series. The line also lacked then-current technologies like SATA III, USB 3, and Thunderbolt, the last of which had been added to every other Macintosh at that point. An email from Apple CEO Tim Cook promised a more significant update to the line in 2013. Apple stopped shipping the first-generation Mac Pro in Europe on March 1, 2013 after an amendment to a safety regulation left the professional Mac non-compliant. The last day to order was February 18, 2013. The first-generation Mac Pro was removed from Apple's online store following the unveiling of the redesigned second-generation Mac Pro at a media event on October 22, 2013.
