Apple's Leopard delayed until October

In the push to get the iPhone out on time, Apple has been forced to delay the release of the next version of Mac OS X until October.

The company revealed the scheduling slip in a press release after the close of the stock market on Thursday. The iPhone is still on track for a June release in the US -- around the time of Apple's Worldwide Developers Conference -- but engineers and quality assurance staffers working on Leopard needed to switch projects to ensure the iPhone arrives as planned, Apple said.

As a result, Leopard will not be ready this spring, a time frame that Apple had reiterated several times over the past few months. A "near final" version of the operating system -- Mac OS X 10.5 -- will be distributed to developers at WWDC for testing. The final release will be available in October.

"Life often presents tradeoffs, and in this case we're sure we've made the right ones," Apple said in its press release.

An Apple representative declined to provide more details on the delay, beyond what was included in the statement.

Wall Street reacted immediately, sending Apple's stock down 2.5 per cent in after-hours trading. "They've shaken people's confidence in their ability to execute," said Roger Kay, an analyst with Endpoint Technologies Associates.

For once, the rumour mill was right on this delay -- though it missed on why that would be. Last month, Digitimes correctly reported that Apple was planning to delay the operating system release until October, but it said the reason was that Apple needed more time to make its Boot Camp software compatible with Windows Vista.

Analysts downplayed that report though, and Apple shortly thereafter released a version of Boot Camp that was compatible with Vista. Boot Camp, which lets users of Intel Macs boot Windows on their systems, will be integrated into Leopard when it ships.

Apple chief executive Steve Jobs previewed Leopard at last year's WWDC, showing off several features such as the Time Machine backup software and Core Animation, which lets developers create new types of sophisticated applications.

The company has said all along that Leopard would be a spring 2007 product, but Apple and Apple watchers have been obsessed with the iPhone since Jobs unveiled it in January at Macworld.

Apple's statement announcing the Leopard delay led off by re-emphasising that the iPhone is expected to ship in late June. Leopard isn't mentioned until halfway through.

"However, iPhone contains the most sophisticated software ever shipped on a mobile device, and finishing it on time has not come without a price -- we had to borrow some key software engineering and [quality assurance] resources from our Mac OS X team, and as a result we will not be able to release Leopard at our Worldwide Developers Conference in early June as planned," it said.

The delay is unlikely to make a huge impact on Mac shipments, according to Kay. Apple won't see any revenue from Leopard in the third quarter, but revenue from the iPhone should offset that, he said.
