    What doesn't gfxcardstatus work with? Like if I start a Mac in integrated only, are there any programs that will still force the discrete? I'm particularly interested in VMware fusion or parallels?

    If there is no dedicated, why would you have gfxcardstatus installed? It won't do anything since there is no discrete GPU.

    Oh, I meant particularly the 750m version vs Iris pro only version. Are there times where applications will force the discrete even when gfxcardstatus was originally set to integrated only?

    Nope. You just have to remember to force it into integrated-only twice, because the first time you force it, gfxcardstatus won't do anything (it's a known bug, but the developer is no longer maintaining the app, so the bug will remain there until God knows when).

    The second time you force it, it'll effectively be integrated-only, and even apps that requires the dGPU won't be able to activate the dGPU.

    Oh, and do this after boot.

    Wow, that looks quite interesting.
    Are you suggesting to switch from "automatic" to "internal" after boot, then again to "automatic" (or "discrete"?) and finally back to "internal"? Is that correct?

    No, switch to internal (it will remain in automatic) and then switch to internal again, and it will now actually switch to integrated. Basically you have to force it to internal twice, because the first time won't work. But it will reset after booting, so you'll have to do it again

    I've noticed issues with my 2015 15" rMBP. Seems like the graphics card doesn't play well with switching. Was causing kernel panics. Deleted it and all is good.
