Mac Pro Now Unavailable for Purchase from European Apple Online Stores
In late January, Apple informed its European distributors that sales of the Mac Pro would cease as of March 1st due to new regulatory requirements that go into effect on that date. At the time, Apple told resellers that it would accept orders up until February 18, a deadline that appears to apply to general consumers as well.
The Mac Pro is no longer able to be sold in Europe because it is not compliant with Amendment 1 of regulation IEC 60950–1. According to information from Apple, the issue has to do with the Mac Pro's unprotected fan blades. Compliance with the new regulation would require fan guards and increased protection of the ports on the electrical system.
Apple's Mac Pro is now unavailable in European Union countries, EU candidate countries, and the European Free Trade Association countries of Iceland, Liechtenstein, Norway, and Switzerland.
Though the Mac Pro has been discontinued in Europe, resellers are still able to sell remaining product after the March 1st deadline. Apple plans to continue to support existing Mac Pro machines and will supply replacement parts.
Apple has also announced plans to offer a redesigned Mac Pro in 2013, following a minor update in 2012.
