We're told that all of Apple's apps are already compatible with Apple silicon - including Logic Pro X - and that converting Intel ones to Universal ones that run on both platforms is a "smooth and seamless" process (we'll have to see about that, though).
The kit spec includes 16GB of RAM, as well as a 512GB SSD, and will come with Xcode preinstalled so that developers can get working on their apps right away.
The automotive announcements came at an annual conference where Apple was expected to signal a departure from Intel Corp's INTC.O nearly 15-year run supplying Mac computer processors.
Apple Inc AAPL.O on Monday announced a system to let iPhone owners unlock and start cars with their devices at its annual conference for software developers. Apple "cannot abandon that as quickly as they want if they want to maintain the enterprise and commercial share for Mac, which is one of their major segments".
"In fact, we have some new Intel based Macs in the pipeline that we're really excited about", he continued.
Apple's first ARM-powered Mac systems will be a 13.3-inch MacBook Pro and new 24-inch iMac, according to a report from 9to5Mac.
This is a monumental shift for Apple but it's not the first time they have done this either. The company's' A-series chips have been used in iPhones, iPads, and its Apple TV boxes for years and the transition to the laptop/desktop is about to finally happen.
The new Apple designed silicon will be designed specifically for the Mac and will allow Apple to bring much better products to market, Srouji explained. Apple Macs account for approx three per cent of Intel consumer CPU sales. Incidentally, the full transition to ARM-based Macs will take about two years.
Big Sur will also include Rosetta 2, which will automatically translate existing Mac apps that haven't been updated for Apple's ARM chip.
Apple plans to ship the first Mac with Apple silicon by the end of the year and complete the transition in about two years. Developers can easily convert their existing apps to run on Apple silicon, taking advantage of its powerful technologies and performance.
As for iPhone and iPad apps, they'll be able to run natively on Silicon Macs too. The rest - people who work all day every day at a computer and need the power to performance ratio you can't get from a tablet - now have hundreds of thousands of apps to fill in the gaps. The kit will have to be returned to Apple at the end of the programme. Microsoft has also tried to use ARM-based chips in its Surface products, but results have been mixed.
"Microsoft's experience with Windows is the blueprint for the potential and the pitfalls of introducing Arm chips to PCs", says Geoff Blaber, an analyst at CCS Insight. But the practical reality of recompiling apps as a stepping stone will take time. This is the same chipset that runs on the iPad Pro tablet.
