The PowerPC microprocessors were a joint initiative between Motorola, IBM and Apple.
It represented an immense step in terms of performance.
It also started the processor war against Intel.

But it was not forever.
The PowerBook G5 never arrived.
Today it seems normal, but at that time it was inconceivable.

Still, it happened.
Mac OS X always had a hidden twin brother that ran on x86 architecture.
Apple made a fairly clean transition through universal binaries, that is, applications compiled for the two architectures.

2.They are not enough anymore.
Intel has not been able to adapt to the current times when extremely efficient and fast processors are needed.
Apple has been able to design extremely fast ARM chips in ultra-portable devices.
iPads are faster than most MacBooks.
That cannot continue happening.
Surely they have macOS running under ARM architecture for years.
Surely Xcode will allow you to compile applications for the two architectures.
