First official new Mac Pro sold sets all-time record for most expensive personal computer at $977,000: “Apple is known for making history by inventing the future, but even its designer could not have predicted a new record shattered on Saturday as a special one-off red version of the new Mac Pro (which is not officially available for sale yet) was sold at a charity fundraising auction for $977,000 — an all-time record for the priciest personal computer ever made or sold,” Electronista reports.
