I see, not being well versed, I see I'm again confusing 64-bit architecture
with double precision. And I'm still confused on what "CPU-architecture"
actually means. Let's see if I get things straight.
Older macs with intel chips can run two different architectures: *i386*
(Intel 32bit) and *amd64* (Intel 64bit). This depends on the OS and the
last to allow i386 was Mojave (10.14). Newer arm64 is obviously only 64bit.
I'm positive this is what it is, but it still strikes me as a bit uncanny
that a computer can have more than one architecture, as my intuition would
tell me that the architecture of my chip can only be of one type. So I
guess I don't really get the concept of "cpu-architecture".
Anyway, things like this should be made clearer for dummies like me in the
manual and stuff.
Cheers
