Apple made know of this stop in sales for the Mac Pro desktop via a letter that they sent to resellers today, citing Amendment 1 of Regulation IEC 60950-1. Unfortunately, the letter itself failed to shed light on just what is inside the Mac Pro desktop that violated said regulatory requirements. This should not come across as negative news to be reflected in the share price, since the high-end professional desktop is more or less a niche product for the company, and sales of the machine in Europe would hardly be a drop in their bucket. Rumor also has it that Apple intends to update the Mac Pro this year, which would mean it will comply with the new European regulations.
