Now I don't know why the external one have full VRAM but the built-in card have 0 MB since both are almost the same chip. This one next is for the external (ultrabay) card: This image is for the built-in card (the one connected to display): With some of this combinations I was able to boot OS X with Nvidia running the display:īoth Nvidia cards were recognised but the built-in card with VRAM = 0 MB the ultrabay card with a whooping VRAM = 2048 MB. Add boot-flag: nvda_drv=1, NVidia=False, npci=0x2000 (I tried all combinations).Set FakeID: 0x10DE0FE9 (other FakeID I tried 0x10DE0FEA and 0x010DE0FE4 and both are for 750M).Ticked Inject EDID (I tried with and without).Ticked Inject Nvidia (I tried with and without).use native tables because Nvidia may not be happy with IGPU patches I used to use before while using the Intel card) Disabled dropping any ACPI table (i.e.

So I connected the external card and so Intel card is disabled and booted to Clover. There are not much difference between them AFAIK. The two Nvidia cards are almost identical and the differences between them can be seen from the image below.

Here's a screenshot from MSI Afterburner software with the mentioned configuration: Q: Can you prove that using the external card will disable Intel card completely?Ī: Definitely yes. Q: So why do you mention / use this card at all?Ī: Because it is the only way to disable Intel card completely without flashing a modded BIOS. It will not work in SLI mode of course and it is not connected to display. Q: Even if you successfully did, what do you expect to get from the external card?Ī: Nothing. These are few questions (and their answers) that I hope they clarify the situation:Ī: To enable Nvidia built-in card (which is not Optimus and is fully connected to display) in OS X Yosemite, in the absence of Intel card Due to a problem we have with that fix for HD4600 that seems impossible to fix, I decided to ditch the Intel card and to try get Nvidia card working with Yosemite.

The easiest way for me to install and use OS X Yosemite was to remove the external card and disable the internal Nvidia card using BIOS (or SSDT) so I rely only on Intel HD4600 which have a fix for Yosemite. Therefor, this thread is NOT to discuss Nvidia Optimus and that OS X will never utilize it, this is a totally different case. Not every configuration of this laptop comes with external graphics card but for those who have it like I do, the third graphic mode above certainly allow for completely disabling Intel card. In this case, the built-in Nvidia card is the main for display and external Nvidia card is only available as a possible way for SLI if activated.

The laptop is in gaming category and that's why there are two Nvidia cards which are able to work in SLI mode in Windows (I know this is not supported in OS X and I don't ask about it). It is important before I go further to describe clearly how these are configured.

The laptop mentioned above have three (yes three) graphics cards: As the hardware configuration is unusual, I will make an introduction of the graphics system on this laptop first. I have a laptop(Lenovo Y510p) and I have a problem to get its Nvidia card working with OS X Yosemite.
