    I would like to use Intel Iris Pro only. I thought there was a way.

    Thanks.

    Use gfxcardstatus to disable the 750M.

    You'll have to click on Integrated-only twice, because there's a bug in the app that prevents iGPU-only from being selected on the first try. It'll work on the second try.

    On the contrary, it actually protects the motherboard so that the 750M doesn't have to activate unless the user forces it to.

    You can do it with gfxcardstatus, be aware that external displays will not work in Iris only mode. The video output(s) are not wired in any way to the integrated graphics card.
