You may have seen reports popping up everywhere as Apple’s new Macs
running its ARM-based “Apple Silicon” chips get into the hands of the
first buyers. They seem to offer remarkable performance while still
managing good battery life, even while a lot of the software they are
running is still written for x86 processors and being translated on the
fly through the “Rosetta 2” emulator layer.
One of the secrets to that performance is that the system RAM is
integrated into the CPU chipset
Yup, that means RAM is not upgradeable on these machines.
