Income for its quarter ended June 25 more than quintupled to $320m, or 37 cents a share, from $61m, or 8 cents a share, a year ago.
Apple sold 687,000 desktop Macs and 495,000 notebook Macs during the quarter, a 35% increase from a year ago.
The company touted its recently released Mac OS X operating system, dubbed Tiger, as its best ever OS release, since it pulled in about $100m in revenue during the quarter.
However, the company projected it would earn 32 cents a share in its current quarter on $3.5bn in sales, below Wall Street expectations.
