By all accounts, a brand new m1/m2 mac is a general purpose computer. It allows arbitrary execution of code, it can be used generally for multiple purposes. This is contrast to special purpose computers, who were designed specifically for a computational task and cannot perform tasks of "general purpose." A Raspberry Pi, a Vic-20, an Apple II, the framework laptop, and yes, the current generation of Macs all qualify.

You're trying to narrow the definition of "general purpose" to mean something else entirely.
