AppleInsider has an article on how the new M1 Macs in fact support USB 4, and not just Thunderbolt 3. I hadn’t realized this at all, but it makes sense as it is new open standard, but amazing that it is before Intel managed to release it. They do need to add more ports though, 2 ports on the laptops when it includes charging is nuts. I have problems with only 4 thunderbolt 3 ports on my imac pro as is.
