![]() ![]() just don't mind the language used! I used a Panasonic Aluminum Polymer Capacitor (. The solution is to replace the bad capacitor with a better part! Louis Rossmann recommended using Aluminum Polymer capacitor because they are highly reliable! Here is the link to his video ( ). Solution was to replace the bad tantalum capacitor not just with a similar part! If you do that, you'll end up with the same issue later down the road. Because the bad capacitor can't handle the voltage anymore, it cause the GPU Panic. When the dGPU is running at high performance settings, it requires a lot more voltage. Results from my research, the issue is the Tantalum capacitor used to regulate power to the dGPU. The downside of this downside is that your battery life will suffer considerably if you run with the dGPU enabled all the time. It won't automatically switch to the dGPU just for mission control. I did a lot of research on this issue when my MBP started to crash (GPU Panic) 5-6 times a day. ![]() The downside is that you have to be running an application that forces the system to switch to the dGPU (or run gfxcardstatus). There are a lot of reports with regards to Apple previously replacing the boards and after a little while, the problem reappears. I will ask over at FreeMind what can be done.My MacbookPro6,2 was experiencing GPU Panics. As soon as you want to open/create a new file, the creation of a window fails: Short flash and the main menu (the application stub I guess) re-renders shortly. But you then only see the main menu (the application stub I guess). You see the startup dialog ("Freemind 1.0.1": Initializing this, that, bla bla) until the app is ready. Removing JVMRuntime=jdk1.7.0_45.jdk starts the app with the iGPU indeed but then does not work. Jdiskreport 1.4.1: After having added NSSupportsAutomaticGraphicsSwitching=TRUE to the ist it then launches with the internal GPU and functions normally!įreeMind 1.0.1: ist was shipped with NSSupportsAutomaticGraphicsSwitching=TRUE and NSHighResolutionCapable=TRUE. Setting NSSupportsAutomaticGraphicsSwitching to TRUE indeed prevents the enforced use of discrete GPU usage! But not for all Java apps! I tested these: Update as of : The newest generally available macOS + Java today is: Unfortunately this option is not included in the standard JVM distribution from Oracle. Otherwise the system uses the discrete graphics by default. This gives a Java application the power of using the integrated card.I'd like to disable the NVidia GTX 750M GPU on my MacBook Pro 15" (Retina, Mid 2014, Mac OS X 10.10 Yosemite). I know I can use GfxCardStatus but I read I could have a more permanent solution by changing some EFI flag. How can I disable the discrete GPU from EFI? I assume this is persistent across multiple reboots. The question is basically whether the command mentioned in GfxCardStatus github issue comment here is correct or not, and how to undo it if it doesn't work.Īn answer to this alone is a correct answer, but it'll be awesome if you can also tell me: I'd also want to know how to undo it if needed. If I disable the discrete GPU from EFI, will macOS think that the integrated GPU is the one installed and will it let me use multiple monitors with it? If you force integrated graphics in GfxCardStatus, Mac OS X (up to Yosemite at least) doesn't allow you to use multiple monitors (even though the built in Iris Pro can do it). Is that true? And if yes, how to do that? I heard that the same EFI setting is responsible for not even showing the integrated GPU to other operating systems than macOS and you have to trick it somehow to think it's macOS. ![]()
