It seems like my new i7 MacBook Pro stays set to the NVIDIA card 100% of the time, when set to switch dynamically. I downloaded and installed Cody Kreiger's gfxCardStatus. (Thanks, Cody!) I saw that my MBP was using the NVIDIA card. I tried quitting all of the programs that might be triggering this – Photoshop, Skype, etc. It was still using the NVIDIA card. I tried shutting down and restarting the laptop. It still stays on the NVIDIA card. I checked to make sure that I had no applications open, at all. Yup, none – and still using NVIDIA. I checked to see that it's set to switch dynamically. Yes, it is. Are there any cicrumstances that don't trigger the NVIDIA graphics card use, in my MBP? I can't seem to create a situation where the dynamic switching chooses the Intel card over the NVIDIA card. I don't consider this a serious issue for me, for several reasons: 1) My MBP is still running at fairly cool temperatures, even with the NVIDIA card selected; 2) The battery life is still good enough for my needs, most of the time, when using the NVIDIA GPU; 3) gfxCardStatus allows me to switch to the Intel card, if I choose; 4) In real world use, I have Photoshop running almost 100% of the time, anyway – so it's proper for my MBP to choose the NVIDIA card, most of the time. Thus, it's not really a problem. However, I still find it curious that I can't convince the dynamic switching to select the built in Intel card under seemingly any circumstances. How do you get your MBP to choose the Intel card? Is anyone else experiencing this?
