Gfxcardstatus

Strangely enough, it DOES allow "Discrete Only" and also allows Dynamic.I had to delete a couple .kext files to get it to boot all the way to login screen.This problem also occurs when booted "Safe Mode".I am still running Mountain Lion 10.8.5ogattaz gives an excellent description of this problem in:#9which I have embedded here:ogattaz commented 2 months agoToday gfxCardStatus is used by a lot of the owners of early 2011 MBPs who have troubles with the external Radeon GPU.Look at the thread example, to be able to boot my MBP 8.2 , I must remove the ATI* and AMD* extensions, but in this case, the selected GPU is the Radeon GPU and gfxCardStatus is not able to force the usage of the integrated GPU because it detects an external display even I have no plugged external display !...note: if I let the ATI* and AMD* extensions in place, my MBP freezes during the boot sequenceIt would be great if we could use gfxCardStatus to always force the usage of the internal GPU.

Manager" to proceed.Do not uninstall the Install Manager, but instead use it to uninstall Catalyst Control Center. In our test, this didn't even require a reboot. Also, leave a note on this page (with the driver version) so we can report it to AMD.My Macbook Pro is having trouble with f.lux, and it flashes sometimes.On dual-GPU machines we write an ICC profile in order to make the "switch" between video cards more seamless. In some older machines, and every so often, this doesn't work so well. To read about how this system works and turn it off if you want, check out our description here:Notes about f.lux changes to ICC profiles.If your Macbook is crashing due to switching between cards, or just to understand when it happens, a really great workaround is to download gfxCardStatus and use only one of the two video cards.My Macbook Pro running 10.8.2 flashes blue when I run Chrome (or really any time my Hybrid graphics card switches.) Sometimes f.lux doesn't work at all. Is f.lux doing this?We think it's not related (we fixed all these bugs.) This problem seems to be reported by people who don't run f.lux at all.One workaround is to download gfxCardStatus and use only one of the two video cards, discrete or integrated (whichever works better with f.lux).-->My computer flickers when I use Parallels. What should I do?You can disable "use Windows gamma settings", and directions are in this post.I use Shades on my Mac, and f.lux is fighting with it.Users have reported flashing and flickering when using these together. We recommend you only use one of these programs at a time.I can't drag the program to the Trash on my Mac.First quit f.lux from the Settings menu, to the left of your system clock. I adjusted my color / gamma settings using Windows "Calibrate Display" or NVIDIA's controls and f.lux removes them. Can you keep these settings and use f.lux?Unfortunately, these systems do not write their settings in a format that f.lux can access (we read VCGT headers only). For better results, we recommend the use of hardware calibrators such as the very good x-rite i1 Display or ColorMunki Display, which write settings in standard ICC files that f.lux can read. If you don't have access to a device like this, you might find a suitable profile for your display online at the TFT Central Monitor Settings Database.Several people

맥북프로 레티나 내장그래픽으로 고정하는 방법 현재 2015 mid Macbook Pro Retina CTO모델을 사용중인데요...요놈이 AMD Radeon R9 그래픽칩을 탑재하고 있어 빠른 그래픽이 필요할 때는 Radeon R9으로... 일반적인 상황에서는 Intel IRIS로 왔다 갔다 하는 변태같은 모델입니다.사실 맥북을 거의 업무적인 용도로만 사용하는 저로서는 외장그래픽(Radeon R9 M370X)이 필요가 없는 상황입니다.하지만 일반적인 윈도우기반 노트북과는 달리 맥북은 사용자가 외장그래픽을 ON/OFF할 수 없고 macOS의 판단하에서 지 맘대로 외장그래픽과 내장그래픽을 왔다 갔다 하며 맥유저에게는 그래픽카드 선택권을 아예 주지 않습니다.전원을 연결해서 쓸때는 외장그래픽에 의한 발열을 빼고는 큰 상관은 없습니다만... 카페같은 곳에서 배터리만을 사용할 때 외장그래픽칩이 작동될 경우 맥북의 사용 시간이 거의 50%정도로 줄어드는 심각한 상황을 경험할 수 있습니다.gfxcardstatus라는 공개어플을 사용하여 제한적으로 나마 내장그래픽칩 사용으로 고정할 수 있지만 근본적인 해결방법은 아니기에 폭풍 구글링하여 해외사이트에서 해결의 실마리를 찾았습니다.EFI(Extensible Firmware Interface, 확장 펌웨어 인터페이스)의 특정값을수정하여 macOS로 하여금 Intel IRIS 내장형 칩만이 존재하는 것으로 인식하게 만들어 외장그래픽을 활성화 못하게 하는 방법입니다. 이 방법을 쓰면 부팅부터 시스템 사용, 그리고 종료시까지 내장그래픽만을 사용하게 된다고 합니다. 아치리눅스로 USB부팅하여 efivars를 마운트하고 gpu-power-prefs-fa4ce28d-b62f-4c99-9cc3-6815686e30f9의 값을 특정값으로 바꾸어 주거나 새로 생성시켜주면 되는 방식입니다.적용방법에 대한 상세한 설명은 원문URL로 대체하도록 하겠습니다. 경우는 gfxcardstatus 프로그램 도움 없이도 내장그래픽으로 고정이 아주 잘되는군요.맥북프로 레티나 외장그래픽 모델을 쓰시는 분들은 참고하시기 바랍니다. powernomics 님을 이웃추가하고 새글을 받아보세요

Hello all. Long story short, my 2011 macbook pro has the dreaded logic board issue. Whenever an app needs the discrete video card, it will reboot. It won't always come back up right away. It will be stuck in a constant reboot. I have to reset the pram, smc, try to go into internet recovery mode, etc. It's a crap-shoot when it will boot up. It usually does but it may take a while.I took it to Apple. They won't repair it because it's vintage. They referred me to an authorized repair center but $ is tight, so I'm looking for alternatives. It's a great computer and runs fine when it's up.I downloaded gfxcardstatus 2.4.4i (running High Sierra 10.3.3) and set it to use integrated only. It was my understanding that it should force any app to use the integrated gpu but apps that need the discrete gpu are still using it, like Chrome and Photos. Perhaps my only way around this is to not use those apps and find alternatives. Just wondering if anyone had any experience with the app and if I'm doing something wrong? Or will it not force apps that are designed to use the discrete gpu to use the integrated gpu?Thanks. MacBook Pro, macOS High Sierra (10.13.3) Posted on Mar 12, 2018 10:32 AM Posted on Mar 12, 2018 10:43 AM Steve Schow writes that he has abandoned further development -- because there are better solutions available [for both the 2010 model and 2011 models]. In particular, the use of ArchLinux bootable CD to gain access to and re-write the EFI on the drive, and permanently disable the discrete graphics chip. This page and scroll down past the list to the blog: are two similar procedure listed. I used the second from MacRumors as it seemed easier. I have made the Arch Linux bootable CD on another Mac, and tried this approach. I now have a perfectly-functioning MacBook Pro late 2011 15-in model with Discrete Graphics semi-permanently disabled. Runs just fine.
