Updating graphics card mac
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.But, unfortunately, many Macs and Mac Book models still rely on 'integrated graphics' to handle graphics, video and animation work.An integrated graphics processor is a small graphics chip that is actually part of the Mac's main processor (CPU) - rather than having a 'dedicated' graphics card (or GPU - 'graphics processing unit'), which is a completely separate graphics card that works alongside the main CPU in order to give graphics performance a much bigger boost.Link to Open GL support by Mac model have their own release for certain Mac GPUs - this is the current driver as of December 2015 However, they are predominantly for the Quadro series of aftermarket cards rather than default cards supplied by Apple.
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.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 Mac Book 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.
