![]() I will ask over at FreeMind what can be done. If you disable the nVidia card permanently, you will should notice an increase in your battery life. Just use your mouse to switch manually between the two when needed. 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. gfxCardStatus places a small icon in the menu bar and displays a small n for nVidia or i for the currently active Intel graphics chip set. ![]() 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. If those files were the issue, then it should work. That insures the files are working properly. Removing JVMRuntime=jdk1.7.0_45.jdk starts the app with the iGPU indeed but then does not work. If you have all those files and your game is still not working: Go into both the 2010 and the 2013 files, double click them, and hit repair on the menu that pops up. 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: Power on your computer while holding Shift key to start in safe mode. Unfortunately this option is not included in the standard JVM distribution from Oracle. Shut down all devices and unplug from MacBook Pro. Otherwise the system uses the discrete graphics by default. This gives a Java application the power of using the integrated card. I had to reboot my Mac following the Twitterrific stall, but otherwise nothing else was harmed.There is a special option which has to be specified in the ist file of the launcher of the application: NSSupportsAutomaticGraphicsSwitching Restarting Bus圜al fixed the problem, and it turns out the program offers an optional setting to not use Core Animation. In my testing, Bus圜al 1.6, for example, wouldn’t advance the month correctly, and Twitterrific froze my machine. ![]() If it is a macro-enabled workbook/template, VBE will keep the status from the last time you save the file. The former is simply a shortcut for disabling the aforementioned Automatic Graphics Switching setting the latter actually forces apps to use limited resources, as if the apps were running on a Mac, such as the 13-inch MacBook Pro, with only an integrated GPU.īefore using the Integrated Only option, though, make sure you quit all applications listed under Dependencies, as some programs don’t take kindly to having the expected GPU pulled out from under them. Hello, If the 'Excel file' you open is not a macro-enabled workbook/template (.xlsm/.xltm), there wont be any code window opened when you open VBE. If you’re especially worried about battery life, gfxCardStatus lets you force the issue by choosing Discrete Only or Integrated Only from the utility’s menu. But the most valuable part of gfxCardStatus to me is that its menu lists which specific running apps are dependencies, or using discrete graphics, so I can quit them when I need to eke out more time from the battery’s charge. ![]() Growl notification whenever the GPU changes.īy watching for these changes, you can get a better idea of which tasks cause your MacBook Pro to use the power-hungry GPU. ![]() You can also configure gfxCardStatus to display a The menu’s icon reveals, at a glance, which GPU is in use: i for integrated or d for discrete. The solution is gfxCardStatus, which runs as a systemwide menu. The Energy Saver pane of System Preferences lets you disable the Automatic Graphics Switching option, but doing so actually forces the computer to use the discrete GPU, an option that drains the battery even faster. The only way to make sure you’re using the integrated GPU is to quit applications that rely on the discrete GPU, since OS X doesn’t let you choose to stick to the latter. So even if you’re working from battery power and trying to minimize battery usage (by turning down screen brightness, for example), you may still be using discrete-graphics-card cycles-and, thus, more energy. The problem is, some applications you wouldn’t think need a lot of graphics power actually rely on features such as OS X’s Core Animation that require the discrete graphics card. Some quick background: All 15-inch and 17-inch MacBook Pro models from 2010 and later, as well as 20 models outfitted with an Nvidia GeForce 9400M/9600M GT, dynamically switch between a low-power (and lower-performance) integrated Intel graphics chip and a power-hungrier (and better-performance) discrete Nvidia or AMD graphics card, based on the needs of running applications. ![]()
