Restart afterwards and the screen will maintain the same colour on both the iGPU and the dGPU. …which gets rid of the existing ColorSync user cache. Sudo rm $(getconf DARWIN_USER_CACHE_DIR).`id -u` So, long story short, execute the following in the Terminal: It took me a while to find it because the title doesn’t immediately give away the fact that it concerns the ColorSync cache. The easiest way to do this (in my opinion), is described by Topher Kessler on in his post titled “How to make ColorSync profiles stick in OS X”. I tried this and it immediately worked, removing the blue-ish tint from the MBP screen (well, after removing the ColorSync cache and restarting the MBP).
I also found the recommendation to reset or purge the ColorSync user cache. READ THIS this video will show you how to change your mac book pro's built in graphics card note when my mouse went off screen i clicked the apple in. And, when you attach an external screen (like I do most of the times), it doesn’t work at all.
I consider this a bad option (it’s not bad software by the way, I’ve used it in the past to monitor the GPU switching), since the dGPU is far more powerful than the iGPU and often you need that power (be it the dedicated memory or the computation power). Very bad on the eyes, especially in the evening.Īfter googling around a lot, a number of posts on the Apple Discussions pages recommend gfxCardStatus, using which you can “lock” the MBP on the iGPU. It would change from its correct colour to a somewhat blue-ish tint. Now, since a while, when the MBP would switch from the internal GPU (iGPU) to the dedicated GPU (dGPU), the screen would change colour. Adobe Photoshop, Google Chrome, Visual Studio Code) trigger the switch, probably because of some low-level GPU call that makes OS X decide the dedicated GPU must be used. It “dynamically” switches between the two on-demand, which means some applications (e.g. I’ve got a mid-2010 15″ MacBook Pro, which was the first having both an integrated GPU (Intel HD) and a dedicated GPU (NVidia Geforce GT 330M).

Only one of them has a display “ Color LCD” connected – that would be the one you’re using right now. Look under the heading “ Graphics / Displays” where you will see 2 video chipsets listed. I found the easiest trick to be looking in the “ System Information” of your MacBook Pro (click the Icon, select “ About this Mac” → “ More Info” → “ System Report“) – later we will see that gfxCardStatus makes it even easier. There are several tricks out there to identify which video chipset is being used. This can lead to unexpected results when developers access this framework without having a real need for it.įor 3D Games, iMovie, and for example Photoshop, this makes perfect sense.įor others it does not … a list of applications is maintained in the Apple Discussion Forum. So when an application access the Core Animation framework, the more power hungry chipset is being used. The switching between chipsets is done automatically and triggered by the use of Mac’s Core Animation framework ( OpenGL, OpenCL, Quartz Composer, and Core Graphics). Dedicated chipsets typically have their own memory. We refer to this chipset as the “ discrete” or “ dedicated” video chipset, for example the “ NVIDIA® GeForce GT 330M“. The other video chipset (commonly nVidia) is power hungry, but with good reason it’s much more capable in handling graphics intens applications like video, games, Photoshop, etc. Integrated chipsets often utilizes some of your main RAM. This is referred to as the “ integrated” chipset and commonly identified on your MacBook Pro as “ Intel® HD Graphics” (OK, you can stop laughing now ). Typically one of the graphics chips (often an Intel chip) is used for regular office applications that are not graphics intense – which takes less battery juice and makes your laptop run longer on it’s batteries. The Operating System automatically switches between the two chipsets as it sees needed – and sometimes not for the right reasons (although I have to admit that my current MacOS X Lion 10.7.3 does seem to do a better job at it than previous MacOS X versions).
Apple equips most of their Unibody MacBook Pro models with 2 video chipsets.
