If they limit a M1 Max beast with so an OS Limitation after they support it in newer macOS, i will leave Apple forever....Finally Apple release mac with HDMI 2.1 port. I think I would buy Macbook Pro 14 with m1 pro or max IF I can use a typec to hdmi2.1 adapter to output 4k120.
There is hope but I think Apple will still add software limitations on the old models...
