In a statement to Gizmodo, Apple publicly acknowledged the vexing display issues plaguing its latest iMac models. The symptoms of these issues, which mostly affect the 27-inch model, include yellow discoloration and screen flickering. In its statement Apple said, "We've addressed the issues that caused display flickering and yellow tint. Customers concerned that their iMac is affected should contact AppleCare." While the company has been too slow in addressing this problem, better late than never. follow link
Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
