I bought Microsoft Office for Mac 2011 University today. I installed it and all of its updates, however it isn't updating to support retina display... I own a 15" rMBP so this is very annoying. Anyone know why?
The most recent Office update is Microsoft Office for Mac 2011 14.2.5 Update. It was released on November 13, 2012. Be sure that you are fully updated. That said, I do not recall any mention of a hardware-compatibility upgrade for Office. There is no mention of the Retina Display-compatibility in the documentation for the latest or any other Office update.
The question is: Do you have a problem running Office on your rMBP?
