Since upgrading to Sonoma using open core on my 2017 MacBook Air clamshell mode will not work I’ve tried turning all the sleep options to never and no screensaver, have tried using amphetamine as well as displaysleep terminal commands. The terminal commands worked on Monterey and Ventura but since upgrading to Sonoma nothing seems to work
If you’re happy keep it and if you notice it lagging or something then think about switching. Everybody doesn’t have the same needs and from the sound of it what you have is just fine. I have a 2017 air with open core to get Sonoma and it’s functional for what I need it and it sounds like u have about the same needs as I do. Just enjoy no need to second guess. Get an external if you need extra space, you can get a 1-2 terabyte drive for less than what Apple wants for a 256 gb upgrade
