Wrong. Lots of Mac users skipped the Liquid Glass OSes. I was one until I bought an M5 that came with it. In fact, I was two versions behind on my M1 because the one before Tahoe also offered nothing that I wanted.

> the same software.

This referring to third-party software (my interpretation) is also wrong. People have wildly different setups, at least among us nerds.

> This can't an issue of a defective Mac.

Again, you don't know that. But your comment later on about two models having said issue is concerning. That said, there's a high likelihood that you run the same software on each.

> I am right now using my M5, on low power mode on a flat surface and it's almost too hot to type on.

If that's the case, I begin to suspect that the physical sensitivity that you mentioned in a different comment is the source. If that's the case, I'm empathetic cause it'd really suck to have that reaction. I can only make my M1 hot enough to noticeably warm up (or get hot) when slamming the CPU / GPU. I would hate for it to feel that way to me during normal use and you have my genuine sympathy if that's your experience on a machine running at normal levels. And if that's it, then get an external kbd and mouse. Not an ideal solution, but it sounds like the best option. Not portable. I know. But I'm looking for solutions here and there may be some compromise needed.
