The tech giant's boss explained that their new in-house chip "unleashes another round of innovation and so I don't want to say a lot about it, other than we're extremely excited about it."
He added: "[We will have] a common architecture across all of our products which gives us interesting things that we can do."
Speaking at Apple's earnings call this week, Cook revealed that iPad sales have jumped 30 per cent and Mac sales 20 per cent, whilst he confirmed that the iPhone 12 will be delayed until October.
Remaining coy on Apple Silicon, he added: "I don't want to make a forever comment but we're a product company, and we love making the whole thing." That's been clear from Apple's iPad and iPhone strategy for some time - and now it hopes to bring the same benefits to the Mac. However, we also know there will be new Intel Macs this year and probably beyond it."
Last month, Cook teased: "We expect to ship our first Mac with Apple Silicon by the end of the year."
However, he confirmed that the full-scale transition is likely to take around two years.
While Geoff Blaber from the consultancy CCS Insight, explained Apple's motivation for making the change.
He shared: "Apple's motivations for doing this include reducing its dependence on Intel, maximizing its silicon investment, boosting performance and giving itself more flexibility and agility when it comes to future products.
"Embracing ARM and making its hardware more consistent across the iPhone, iPad and Mac ranges is a strategic necessity, but there will be inevitable bumps along the road."
Meanwhile, Cook recently claimed technology has paid its part in bringing about societal changes.
He said: "If you look back in time, some of the most dramatic societal changes have occurred because someone captured video.
"This is true about things that happened in Birmingham; it was true about things that happened in Selma."
