OS X Mavericks has not yet been released however the OS X Mavericks Developer Preview is Beta Software and with the exception of changes to Localizations in gfxCardStatus it appears there hasn't been other work on gfxCardStatus in over 9 months so even though the gfxCardStatus requirements show OS X Lion (10.7) or newer and 2008-2012, 15-17" dual-GPU MacBook Pro, I'd venture to say that gfxCardStatus may not work properly in the OS X Mavericks Developer Preview and since it appears core development hasn't moved in over 9 months that gfxCardStatus may also not work properly in the OS X Mavericks when it is released. After reading various things on the internet, I found out about the gfxCardStatus app which I used and noticed my machine is using the discrete graphics card.
It seems that you need to force the system to use the nvidia chip before CUDA will work. Graphics switching to Discrete after all dependencies close. These things ship with Intel HD graphics & nvidia GT 330M graphics. Software & Apps zum Download, sowie Cloud-Dienste für Windows, Mac, Linux, iPhone, Android. I have gfxCardStatus set to display a notification whenever the mode is switched. Some apps and an external display force discrete mode anyway. You cannot switch to Integrated only if an app is already using the discrete processor. My testing was further supported by the fact when I plug in my 27" Thunderbolt Display while gfxCardStatus is set to Integrated Only, whether or not the Virtual Machine is running, the Thunderbolt Display stays dark until I select either Discrete Only or Dynamic Switching as it requires the use of the Discrete GPU. Hello everyone, Am trying to tinker with CUDA on a new MacBook Pro machine. You can also switch between using Integrated only, discrete or dynamic switching. I'm using VMware Fusion 6 under OS X 10.8.3 and when I set gfxCardStatus to Integrated Only that is what's being used while running a Virtual Machine! I based my original reply on the fact that gfxCardStatus reports that Integrated Only is what's being used and the analysis of sampling of the vmware-vmx process is not showing any calls to the GeForceGLDriver until I select either Discrete Only or Dynamic Switching. Keeps switch secure in either the ON or OFF position and helps prevent accidental connection/disconnection of power during maintenance or installation of electrical devices. My VM guest OS is currently mostly idle, and it is reporting hefty 50+ energy impact. On Mavericks, when you open Activity Monitor, it still reports vmware-vmx process as using "high performance" discrete graphics.
