Strong sales of Apple's iPod portable music device helped the company to post net profits of $63m for the first quarter of its 2004 financial year.
The figure compares to a net loss of $8m for the same period a year ago.
Apple said that it shipped 733,000 iPod units during the period, up 235 per cent from the year-ago quarter. It also sold 829,000 Macs, representing an annual growth rate of 12 per cent.
Revenue for the first quarter reached a four-year high of $2bn, up 36 per cent from the year-ago quarter.
Gross margin was down slightly at 26.7 per cent, from 27.6 per cent in the same quarter last year.
The company reported that international sales accounted for 44 per cent of its revenue during the period.
Apple chief executive Steve Jobs said in a statement: "It was an outstanding quarter for Apple, with double-digit unit and revenue growth and over 730,000 iPods sold."
Chief financial officer Fred Anderson added: "Looking ahead to the second quarter of fiscal 2004, we expect our third consecutive quarter of year-over-year double-digit growth in both revenue and earnings, with revenue of about $1.8bn."
