These rumours (or general desire?) about Apple considering ARM-based macOS machines won’t die… but there are so many questions that needs to be answered eventually. A) Does Apple needs to replace the entire product line from the entry level to the top? Why? B) Is Intel instruction set need to be emulated from day-one or Apple could simply choose to go native-only at the risk of not having enough apps for this nascent Mac hardware? C) The desire to control the whole stack makes sense for a product line like the iPhone (which represents the vast majority of Apple’s revenues) but for Mac hardware, really?
We may find some cues to possible answers by looking at Apple’s efforts on the iPad Pro side and Catalyst. They want to build momentum for new software on macOS with the popularity of the iPad platform. Why? I’ll let you make your own conclusions
