April 12, 2007 (IDG News Service) — Apple Inc. said today it won’t release Mac OS X 10.5 “Leopard,” the next version of its operating system, by mid-June as planned, blaming the delay on the iPhone.

In a statement posted to its own hot news page, Apple said that it borrowed some key software engineering and quality assurance resources from its OS X team in order to keep the iPhone on track to ship in June. As a result, the company won’t release Leopard as planned at its Worldwide Developers Conference, which takes place June 11-15 in San Francisco. “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 QA resources from our Mac OS X team,” Apple said in its statement. “As a result, we will not be able to release Leopard at our Worldwide Developers Conference in early June as planned. “While Leopard’s features will be complete by then, we cannot deliver the quality release that we and our customers expect from us,” the company said.
