The first Apple Mac on its own processor will appear this year
The transition to their processors will take 2 years – Apple is still developing devices based on Intel, so it will not be able to immediately switch only to chips based on ARM.
The most important information is the ability for iOS and iPadOS applications to run on MacOS in the future. “Most applications will just work,” Apple says, bearing in mind that no special steps are required to transition and launch.
Apple’s own applications will be updated to support the new chip.
Microsoft is working on Office updates for the new processor, and Word and Excel are already working on it. Apple also showed off Lightroom and Photoshop running on new computers.
Apple previously used Rosetta to migrate PowerPC to Intel-based Macs, and Rosetta 2 will automatically migrate existing applications during installation. That is, even if the developers have not completely updated their products, they will still work on the new chip. Apple also uses virtualization to run Linux versions on new Macs.
Apple’s move to ARM followed Microsoft’s similar move. She began this work before the release of Windows 8 in 2012, and even released the Windows RT operating system for ARM-based hardware. Since then, Microsoft switched to ARM and, together with Qualcomm, integrated the SQ1 processor into its Surface Pro X device.
