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
