Apple Finally Buying AMD CPUs? Pointers to Ryzens Found in MacOS Beta
Since its switch to the x86 machine architecture from PowerPC in the mid-2000s, Apple has been consistent with Intel as its sole supplier of CPUs for its Macbooks, iMac desktops, and Mac Pro workstations. The company's relationship with rival AMD has been limited to sourcing discrete GPUs. If pieces of code from a MacOS beta is anything to go buy, Apple could bite the AMD bullet very soon. References to several AMD processors were found in MacOS 10.15.4 Beta 1. These include the company's "Picasso," "Renoir," and "Van Gogh" APUs.
It's very likely that with increasing CPU IPC and energy-efficiency, Apple is finally seeing the value in single-chip solutions from AMD that have a good enough combination of CPU and iGPUs. The 7 nm "Renoir" silicon in particular could change the mobile and desktop computing segments, thanks to its 8-core "Zen 2" CPU, and a "Vega" based iGPU that's highly capable in non-gaming and light-gaming tasks. AMD's proprietary SmartShift feature could also be leveraged, which dynamically switches between the iGPU and an AMD discrete GPU.

I think AMD is just waiting for Inte'ls response to Ryzen 4000 and then drop the bomb :-).
Ryzen 9 will give AMD a nice margins as a premium product.
Apple's marketing department would have to no trouble creating a new product brand with a more "Premium" image than PRO with new AMD CPUs across the whole product spectrum running faster and cooler.
"faster" - unknown
Being a fan of AMD is one thing. But man, you're flying really high.
Next gen (2020) MacBooks will use 10th gen Intel CPUs.
And by the time Apple finalizes specs for 2021, Tiger Lake U will be around. And it's not like Intel couldn't make 8-core Ice Lake U if Apple orders that...
x86 will not be killed off until we have something better, and we don't have that yet. The whole RISC vs. CISC argument was pretty much defeated back in the early 90s when x86 designs moved to micro-operations, achieving the best of RISC and CISC in one. All current x86 microarchitectures use their own custom internal instruction set, so this claim that they use a 50 year old instruction set is just plainly wrong. ARM is not going to come close to x86 performance wise. ARM does by design use more instructions to do the same basic work, and most of the x86 ISA improvements since the early 90s involves instructions which does more work, and if ARM is ever going to compete with this it needs to become CISC. The future advancements for x86 involves even more advanced instructions; including for "threadlets" and more SIMD. The original arguments in RISC vs. CISC wasn't really about x86 vs. ARM, but the old specialized mainframe instruction sets used in the 70s. The argument back then was that you could make a simpler CPU and just run it at higher clocks to achieve the same performance, while costing much less die space. But this was not really relevant for comparison with x86, this was targeting those intricate mainframe CPU architectures of the time. Today we all know that clock speed scaling will be limited by the power wall regardless of instruction set, so most of the "advantages" of RISC is already gone. Right now the only major advantage that remains is for low-power devices which don't really need performance.
All current ARM-based CPUs rely heavily on specialized hardware accelerated features to do any real work, much more than x86 CPUs, otherwise your phone, your tablet, your blu-ray player and your "smart-TV" wouldn't stand a chance to do their intended work. When it comes to general purpose high-performance workloads, ARM doesn't stand a chance vs. x86, which is why we don't see it in "high performance" laptops and desktops. So to answer your question; Apple will not move to ARM until they decide to kill off their "real" computers, which may happen eventually considering how they keep undermining their own products for professionals/prosumers.

Apple did something similar with Mac OS X during the PowerPC era. While users only saw PowerPC machines, Apple secretly tested Mac OS X on x86 computers. Ultimately, when IBM couldn't provide the performance that Apple demanded, Macs simply switched to Intel.
However, it doesn't necessarily mean anything. For all we know, it's just a backup plan for a backup plan, or maybe the strings could have been brought into the code by pure chance or some other unknown reason.
edit: not saying that's good justification, but....
I know that some idiots buy Macs just because it's Apple and it's cool to have one and they just use it to browse Facebook, but that's the 1%, not the 99%.
And besides, the only dual core Macs left today are the Macbook Air and the lower-end 21.5-inch iMac. And the latter one you can configure it up to 6 cores.
Granted, 1100 US dollars for a dual core laptop feels excessive.
Hell, I thought that those are pure ripoff when the first 2c/4t Clarkdale 32nm i5s were released in 2010, the i5-600 series.
My bet: Comet Lake @14nm. Nope. Still 8 at AMD camp. Not that it makes sense in 15W anyway. That's a very simple question. Because someone buys them.
