Unexpected strength in Mac sales along with the previously-predicted strong staying power of the iPhone 6 line has helped Apple see record-breaking performance for a fiscal second quarter this year. The company sold more than 61.17 million iPhones, about 75 percent of the number sold during the holiday quarter, which is usually followed by a drop of about 50 percent. Macs sold around 4.56 million units, another record for a fiscal Q2 and up 10 percent year-over-year.
