> particularly stuff like Parallels, IntelliJ or MS Teams for whatever reason routinely manage to prevent sleep or to randomly activate and hog the dGPU mac os is nice enough to allow applications to prevent sleep. Check "pmset -g assertions" to point out the culprit. A couple years ago it was Chrome for me. It kept an assertion saying "WebRTC has active peer connections" on all the time. This has only lead me to have a pathological hatred for WebRTC and I turn it off in all my browsers now. As for the dGPU, i've never had one but I do have a feeling that spells trouble, especially with these electron apps and their Helper (GPU) processes. I'm old fashioned enough to do most of my work on desktops that are plugged in and only buy lightweight laptops (13-14 inch mbpros wit no discrete GPU).

I know who the culprits are, Activity Monitor shows it in the Energy tab. But since it's sporadic, I sometimes forget to look into Activity Monitor if I'm in a rush, and for fucks sake this is not a problem that should exist in the first place. I mean, yes, I've had more issues back when I still used Windows, but my Apple gear costs thousands of dollars, I expect better quality. I expect that if the system knows that my intent will not be successful (because some application locks suspend) that the option is either not available/greyed out or that I at least get a goddamn prompt "XYZ is locking suspend. <Abort attempt/Force suspend>". As for Electron, yes, Teams is cursed in that regard (as it is in locking the dGPU), but for me it's usually Parallels, closely followed by IntelliJ that randomly messes up suspend. Neither of them are Electron.

  > I mean, yes, I've had more issues back when I still used Windows Tbh I don't understand why an OS would allow applications to prevent sleep either, but you mentioned MS Teams and I mentioned Google :) I don't think IntelliJ ever prevented sleep for me, but I mostly used the Android Studio flavor. I've caught it using up all my ram though if i left it on for weeks. As for Parallels, I've never tried to close a laptop with a running VM on it. I don't know why, but I always suspend the VMs manually (from the Parallels menu for example) if i use them.
