Apple makes its own drivers & they are included in the OS updates. The way to be up to date on drivers is to always be running the latest OS.
Download for Mac. To check for updates and install the latest version, first launch Elgato Video Capture and then select 'Check for Updates' from the menu. The software update will install automatically. Download Elgato Video Capture 2.0 for Mac. Elgato Video Capture 2.0 will work on an Intel Mac with 10.11 or later.
There is debate over whether Apple make the entire driver set themselves, or just take NVidia/AMD's core code & add their own hardware/OS-specific code to it. The latter seems more plausible to me, but either is just speculation.
The end result, though, is that there are rarely issues with Apple graphics drivers & regular software or games; again speculation, but for games I imagine they write to a pre-defined rule-set, rather than try to constantly be pushing the boundaries. As noted elsewhere, NVidia themselves make OS X drivers for Quadro cards but these are aftermarket cards anyway, not supplied in any Mac build option available directly from Apple. Apple provides core drivers, currently up to OpenGL 4.1 or 3.3 - depending on your card, of course - plus legacy drivers for OGL 2.1 compatibility. Which one you get to use in any particular game etc is up to the writers of that game. Traditionally, if your card has full OpenGL support for the first monitor, it will also have it on the second, unlike many PC cards with 'clipped' performance on the 2nd monitor. After comments & other answers here NVidia do have their own release for certain Mac GPUs - However, they are predominantly for the Quadro series of aftermarket cards rather than default cards supplied by Apple.
There is also support for some cards which have been legacied by Apple - namely the GeForce 680, 285, 120 & 8800 There is mention of beta support for some recent mobile cards, presumably as Apple are dropping legacy support on these in favour of AMD in the current lineup. Besides the drivers that Apple bundles with OS X updates, Nvidia also provides their own driver updates for their GeForce cards — yes, even the 'mobile' cards that Apple puts in Macs. As far as I know, this is not true of AMD and Intel.
In the case of your Retina MacBook Pro with an Nvidia card, there's beta support with Nvidia's latest drivers. Nvidia's graphics drivers for OS X can be downloaded straight from their website, and as such they're sometimes called Nvidia Web Drivers. They're somewhat hard to find if you just go through Nvidia's driver search feature, but they're an easy find if you just Google 'Nvidia driver OS X' + your OS X version (e.g. For example,. As it says in the release notes, support for some newer models of iMacs and MacBook Pros with GeForce cards is in beta. Note that I don't recommend installing Nvidia's drivers (especially beta ones) unless you know what you're doing, and you have a good reason to switch from the default (Apple-provided) ones that come with OS X.
The default drivers are probably more thoroughly tested and stable, less likely to break your Mac, and are supported officially by Apple. If you do install the Nvidia driver, though, you'll always have the option to switch back to the default driver or even uninstall the Nvidia driver via System Preferences. You'll also be able to update the driver from there. A good reason to try out Nvidia's driver might be if you use your Mac for gaming, or you run any other apps that use OpenGL.
On my MacBook Pro with OS X 10.11.2 and an Nvidia GT 650m card, Cinebench's OpenGL test gives a very slight edge to Nvidia's drivers (52 fps) vs. Apple's (49 fps). To hazard an educated guess, I would say that driver updates are most likely rolled into Mac OS X version upgrades and point updates. If you're concerned about the updates available for your particular card, (especially if it is not original to the Mac you're using,) it behooves you to visit the manufacturer's respective web sites to check. You mentioned NVIDIA: here's the to the drivers available for download. Looks like plenty of options for many operating systems. (Mac OS X NVIDIA drivers are only available for Quadro-series boards, tho'.).
It looks like Apple doesn't really bother to update the graphics driver. On a Mid 2014 MacBook Pro, running High Sierra, System Report tells me that the driver was last changed in October (so less than a month ago from when I'm writing this, roughly coinciding with the release of 10.13.1). However, the info text says the driver is based on Geforce 355.11, released in 2015. I only realized all this because I had massive performance issues after the upgrade to High Sierra (with its brand new graphics subsystem, Metal2), so basically I wondered the same thing, 'Do I need to update the drivers?' With the drivers from Nvidia it's now a lot smoother. So to answer your questions (2 years later, but well):.
You find the version of the graphics driver under: Apple Menu About this Mac System Report Software Extensions Geforce. But don't trust the date, check against the Geforce version. IMHO definitely install the latest Nvidia drivers, especially in High Sierra. Apple seems to touch them on the surface, but you will not get proper updates of the underlying driver.
Little as I care for troubleshooting Windows issues, reader Don Phillips writes in with a Windows concern that’s right up my alley. We pens: I have one of the first Mac Pros and have two monitors plugged into it. The ATI Radeon HD 2600 XT graphics card in it was producing weird lines on my screen so I replaced the card with the Nvidia GeForce 8800 GT that Apple started selling. Video looks great on my Mac but now I’ve got a problem with Windows.
I’ve installed Vista under Boot Camp and when I boot into Vista I can use only one of my monitors—the other stays black. Vista’s Displays Settings control panel is no help because it tells me I have a generic VGA adapter. Have you ever heard of this problem?
Heard of it?! Dude, I’ve lived it! I too was unhappy with the performance of my Mac Pro’s graphics card so, like you, I took the plunge and paid Apple $280 for the NVIDIA GeForce 8800 GT (early 2008) Graphics Upgrade Kit for Mac Pro. Installation was as easy as can be but, as with your Mac, when I booted into Vista running under Boot Camp, my Apple 20-inch display appeared as expected but the Dell 20-inch display next to it remained dark The solution is to remember where you are.
Your Mac is now, for all intents and purposes, a Windows PC. In order for it to produce the dual-monitor goodness you’re looking for, it needs a Vista driver specifically made for that card rather than the generic (and unworthy) driver supplied by Microsoft. You can find that driver on. When you reach that page, click the Drivers and Downloads tab and download the Windows Vista 32-bit version of the driver.
Install it, restart your Mac (booting again into Boot Camp, natch), and then right-click on the Vista desktop and choose NVIDIA Control Panel from the contextual menu. In the window that appears choose the Set Up Multiple Displays entry and in the resulting pane, choose the option you want (choose the Configured Independently From Each Other—Dualview option to extend the Vista desktop across the two monitors).
