Apple's transition to Intel processors continues to gather pace, and developers are churning out Universal applications (which work natively on both PowerPC and Intel-based Macs).

While other stories dominated the post results news agenda, Apple chief financial officer, Peter Oppenheimer, confirmed the speed at which the Intel transition is gathering pace.

Speaking during Wednesday's third quarter results discussion, the Apple executive said: "We have released Universal versions of Apple's consumer and professional software applications and our third-party developers have released over 2,900 universal applications."

While some applications - notable those within Adobe's Creative Suite - won't debut in a native form for Intel processors until next year, the majority of software most Mac users employ should be running natively on Intel processors by autumn, Oppenheimer surmised.

"We expect that over 70 per cent of the 500 applications we consider most critical to our customers will be available in Universal versions by the end of September," he said.

In terms of Mac sales, he confirmed 75 per cent of Macs shipped in the last quarter ran on Intel chips.

"We continue to be very happy with our progress and our developers' progress in the transition to Intel. We have now introduced the iMac, MacBook, MacBook Pro and Mac Mini with Intel processors. We are solidly on track to transition the Power Mac and Xserve by the end of this calendar year," he promised.

Apple CEO Steve Jobs described the Intel migration as: "The smoothest and most successful transition that any of us have ever experienced."
