I use a 13 inch M3 Air (16 GB ram) with goland and pycharm. It's the best dev machine I ever owned, everything is a breeze, and the machine is super lightweight. I don't really notice thermal throttling... but then again i dont run LLMs locally or anything like that.
I used[1] jetbrains tooling quite a bit on my m1 air and never had problems, though I did opt for the 16gb ram version. The newer models are presumably at least as performant if not better?
([1] These days my daily driver is an m1 mbp of some whizzbang 32gb variety, which only replaced the mba because my spouse wanted a travel machine and the mbp came for the low low cost of being caught in the late 2022 startup crash. For day to day ordinary backend dev work there really isn't a noticeable difference in my experience, except I guess the mbp is more awkward when working-from-couch. arm vs x86 was sometimes a little awkward around launch, but I can't remember the last time it was an actual hassle.)
Using Rider on an Macbook Air M2 (24 GB RAM) -- admittedly, pretty small/simple code-bases for the most part. Great performance. Only issues come when I need a lot of docker containers running too, especially if they're not ARM images. With that I don't notice performance issues - but the battery drain is noticeable at that point.
I have an M1 for reference, with only 8GB RAM which is the real limiter here. I *can* use Jetbrains IDEs and I *can* build/develop software on it. It's a bit sluggish but doable. I try to not code on that machine, but sometimes it's the only machine I have available when I need to look at something.
This really looks like an amazing computer if it can handle long IDEA hours on medium projects.
