as most of you know, today is the launch of WWDC with the keynote.
The last subject was the new MacOS called "Big sur". Changes were demonstrated as you may guess, but thing is there was a twist. Big sur was not demonstrated using "regular" Macs, but on Apple Silicon Macs, yep you read it right !
Apple did not talk about ARM CPUs, but about Apple Silicon, we all know what that means. In short:
- There will be Universal apps, that is both the Intel binaries and Apple Silicon binaries included. This way they can work on both type of Macs
- Rosetta 2 will be used to translate old apps at install time
- These new macs will run iPhone and iPad apps unchanged
As far as I understand, that is the new logo:
To support old and new apps, Apple will use Rosetta 2, integrated emulation software, to enable ARM-based Macs to run Intel code. In the prior PowerPC to Intel transition, Apple used Rosetta to let PowerPC apps run with performance compromises on new Intel machines, but Apple says the performance should be much faster for Intel apps running on ARM Macs. Additionally, ARM Macs will be able to run iPadOS and iOS apps.
Apple says that it will ship its first ARM Mac by the end of 2020, and plans for a two-year full transition. It’s worth noting that similar language was used ahead of the Intel switchover in 2005, but Apple completed the move “ahead of schedule” in only a year. For now, developers will have access to an A12Z-based Mac mini Developer Transition Kit in the interim. The machine will include 16GB of RAM and a 512GB SSD for storage, but will not be available to regular consumers.
Emphasizes by me.
Lots of information will come in the next days.
