kalimax Posted August 22, 2011 Share Posted August 22, 2011 Hi all, I'm trying to add VRAM to my Snow Leopard OSX guest OS, but it's limited to 8 MB even though I set the guest Video Memory to max 128 in VirtualBox guest settings. I also noticed if I use the built in VirtualBox EFI feature, the VRAM limits to 4 MB! Even worse, that firmware doesn't support resolutions over 1440x900. At the moment I'm using the Chimera bootloader from the latest [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], which allows for higher resolutions but no VRAM over 8 MB. Any ideas? Do I need to load another driver in the guest, if so which one? Here's the setup: sw_vers guest OS: ProductName: Mac OS X ProductVersion: 10.6.8 BuildVersion: 10K549 Virtualbox: 4.1.0 snow.vmx (guest config): <Display VRAMSize="128" monitorCount="1" accelerate3D="true" accelerate2DVideo="false"/> (it doesn't matter if I change 3D or 2D settings, or even lowering 128 to 64 or 32, still 8 in guest!) system_profiler in guest OS: Display: Type: GPU
