Apple has announced a third fall media event as expected. "One More Thing" We think this event will focus on ARM-based Apple Silicon processors and will take place on November 10, 2020.
The event will be streamed from the company's Apple Park headquarters starting at 10 AM PT. Apple decided to split its traditional fall media events into three separate streams due to the pandemic.
Big Sur, macOS 11, will be the first Mac operating system to support both Intel CPUs and Apple Silicon processors. Apple Silicon Macs will be able to run iOS apps with little to no modification.
Apple has a great record of transitioning from different hardware platforms.
Apple's first transition to a new hardware platform began during the late 80s. Motorola was having issues clocking it's 68040 processors to higher clock speeds to compete against the Intel 486 platform. Apple's software tools allowed developers to ship products with code for both sets of processors in the same program.
The second transition was the Classic OS to OS X. With the introduction of OS X 1.0, Apple shipped the ability to run Classic applications. Developers had the choice to recompile their products to take advantage of Apple's carbon technology, which allowed them to run natively. Many developers chose to allow their product to run under the Classic environment, a fully self-contained environment that interacted with the OS X operating system.
Apple's transition to Intel began in the early 2000s. When the announcement was made that Apple would transition to Intel, Steve Jobs admitted that Apple had a dual development environment where each previously shipped version of OS X had been developed to also run on Intel processors. Using a Rosetta technology, Apple's Intel Macs could run programs written for its PPC Macs at 50% to 80% performance. This allowed developers to update their software packages to full intel compatibility without scrambling to get their product out at the time of the introduction.
Apple's experience with ARM goes way back to the Newton, and the original iPhone. The original iPhone, iPhone 3g, and iPhone 3gs were built using apple branded Samsung ARM processors.
With the advent of the iPhone 4 in 2010, Apple transitioned to its own designed processors called the A-Series.
In the years leading up to 2020 Apple has increased the power and the performance of these processors. Developers were given a chance to get a Transition Kit which included a MacMini using the A12Z processor which is the same processor that is running in the latest iPad Pros. A newer design of the chip which is the A14 was released on the iPhone 12.
Right now, we have no idea which processor Apple will place in their new ARM based Mac computers. My guess is their Mac's will be designed with processors which are specifically developed for their desktop systems which will be more powerful than the one's in their portable products.
