Apple has revealed that the Y2K bug caused "a few minor malfunctions" in its IT systems, explaining that the issues did not impact on its bottom line. Some of Apple's business systems are not run on Macs.

The admission came in Apple's quarterly report to the Securities and Exchange Commission. Apple spent $10 million preparing for year 2000. The company took pains to point out that some of the flaws were attributable to its dealings with third-parties, who experienced crashes and suffered downtime.

The company said there might be further minor malfunctions of its IT and non-IT business systems, but denied these would have a significant impact on its operations or finances.
