What's stupid is that it is September 2021 and the MacBookPro is still not using Apple Silicon. I don't count that entry thing with the MBA chip.
When Apple transitioned to Intel, Steve Jobs made sure the very first machine they updated was single most important machine: the MacBook Pro. Not only did they need to prove that it would work and be viable, but this is what all the developers and professionals use (the high end Apple notebook).
15 years later it is still true. The most important machine in the lineup is the MacBook Pro, and it was delayed incessantly, allegedly because of the mini-LED display. Something absolutely no one needs or cares about. So here we are 15 months after the announcement of Apple Silicon transition, without a MacBookPro. Absurd and inexcusable.
AFAIK MacBook Air is currently the best selling MacBook. But that’s not relevant.
With Intel transition Apple had no other choice than start with the Pro, as they were unable to make competitive pro laptop with PowerPC and Intel had Pro chips readily available.
Apple silicon is coming from phones – the low end. It makes more sense to start with the chip that needs the least amount of extra power and new features (which needed to be implemented from scratch).
If Apple had decided to start with the Pro, they’d had to start the transition later. Maybe a full year later. Why throw away full year of low end M1 sales? This launch order makes more sense also technically, and gave more time for developers to fix and optimize pro SW for Apple silicon before releasing Pro machines.
By my experience, rumors about delays are usually made up to cover up other rumors about made up release dates.
If the MacBook Pro is launched with a CPU based on A15, it’s clear that it was always planned to be released after iPhone 13 (by always I mean it was decided years ago, like 2018 or something). All we have to do is wait to find out.
