thanks for the help on point 4. Such a pity about the graphics and VGA output...would have made such a powerful Mac alternative.

Hi there, I've had major success following this forum and have pretty much a 99.9% successful Mavericks install on my E6420 2720QM i7 Laptop with HD 3000 and NVIDIA NVS 4200M 512 MB Graphics. However, I could do with some clarity if the following is possible with the MacOS build: 1. Can both the HD 3000 driver and nVidia card be run at the same time and switched within Mavericks to the preferred one needed? Currently I have them working separately and I need to go into the BIOS, enable Optimus to get HD 3000 working (which seems to give a bit better battery life (as expected)). To get nVidia going, I need to disable this again. I have tried patching with MaciASL, but can't seem to get them both working at the same time. 2. Based on point 1, did anyone get the external VGA/HDMI working for connecting to a Projector? Mine is not working currently. 3. The battery in Windows operates for around 5 hours, however with the supplied smart battery kext, I get under 3 hours. Unless MacOS uses more battery than Windows? 4. Lastly, when booting into OS X with IGPEnabler=Yes for HD 3000 graphics, the boot sequence takes noticeably longer, and when I get to the desktop I get a 'Bluetooth keyboard connection' because a keyboard cannot be found, although the keyboard and mouse works fine. If anyone has any valuable info to share on the above, would be greatly appreciated. Thanks
