Ahead of a modular Mac Pro, Apple said to ready a dedicated API for writing device drivers
Apple is readying a novel developer API for writing macOS device drivers, but what does it receive got to practise amongst a rumored modular Mac Pro that could hold upwards previewed at WWDC 2019 on June 3?
In a word, a lot!
9to5Mac‘s Guilherme Rambo reports that macOS 10.15 includes a novel API developers tin reach notice exercise to write device drivers. Let me briefly explicate why this is a really big deal.
The low-level device drivers layer allows macOS to communicate amongst hardware devices attached to your calculator too chips on its logic board, such equally the GPU. Each device, similar a mouse or a printer, has its ain driver. Apple offers an object-oriented framework for developing device drivers, called the I/O Kit framework, that’s both modular too extensible.
A manufacturer tin reach notice exercise these I/O kit resources to create a custom macOS driver for their device inward an officially sanctioned way. Graphics cards, PCI too PCIe cards, scanners too printers typically require custom macOS drivers inward lodge to piece of occupation amongst your computer.
When it comes to graphics, third-party back upwards is severely limited. Basically, Apple writes its ain drivers—and merely for the specific GPUs that send inward Macs. H5N1 few years back, it stopped using Nvidia GPUs altogether too thence newer Macs are express to Intel or AMD graphics.
This has created problems for creative pros who oftentimes prefer to convey payoff of Nvidia’s fantastic graphics cards to accelerate video editing too other demanding work. If you’re individual who owns a “tower” Mac Pro (it came earlier the cylindrical MacPro 6,1 model), y'all could exercise Nvidia’s PCI-E graphics carte du jour internally amongst their spider web driver.
Unfortunately, that’s no longer the illustration amongst the latest macOS Mojave software. As a result, demanding customers who demand Nvidia are instantly forced to downgrade to macOS High Sierra, which sounds peculiarly stupid given Mojave’s rich back upwards for external GPUs, or eGPUs.
As AppleInsider position it:
This conclusion makes absolutely no feel amongst eGPUs instantly beingness explicitly supported inward macOS. They piece of occupation fine inward Windows, too thence it’s non a technical limitation. Some tasks perform improve on AMD too some on Nvidia, it is a fact of silicon. There is no argue beyond marketing too user-funneling to prohibit exercise of the cards on a software level.
No, at that topographic point aren’t a ton of eGPU installs. Yes, a skillful percentage of those users are fine amongst AMD cards. But, it is absolutely overly user-hostile to non permit Nvidia to unloose the drivers non merely for hereafter eGPU use, but for the non-zero per centum of those users who are keeping the sometime Mac Pro alive.
As AppleInsider separately noted, the exclusively 2 Nvidia cards that transcend away along to piece of occupation amongst Mojave are the older GeForce GTX 680 too the Quadro K5000 models. But why is it that now, inward 2019, at that topographic point aren’t whatsoever functional Nvidia drivers for Mojave at all?
It’s Apple’s fault, Nvidia publicly acknowledged inward 2018:
Developers using Macs amongst Nvidia graphics cards are reporting that afterwards upgrading from macOS High Sierra 10.13 to MacOS Mojave 10.14 they are experiencing rendering regressions too dull performance.
Apple fully controls drivers for macOS.
Unfortunately, Nvidia currently cannot unloose a driver unless it is approved past times Apple. Our hardware plant on High Sierra 10.13 which supports upwards to (and including) Pascal.
AppleInsider spoke amongst several dozen developers within who experience that higher levels of the fellowship killed back upwards for Nvidia’s higher-end cards. According to i developer:

It’s non similar nosotros receive got whatsoever existent piece of occupation to practise on it, Nvidia has non bad engineers. It’s non similar Metal can’t hold upwards moved to Nvidia amongst non bad performance.
Somebody merely doesn’t desire it there.
That “somebody” likely management.
In other words, for legal too licensing reasons Apple at some signal decided to drib Nvidia too exercise AMD GPUs inward Macs. But we’ve been told to hold off a modular Mac Pro this yr too “modular” implies the mightiness to swap the CPU, GPU, memory, storage too other components.
With that inward mind, releasing a modular pro desktop that doesn’t convey Nvidia cards because Apple isn’t allowing Nvidia to write its ain macOS drivers merely won’t cutting it inward 2019.
I mean value Apple is aware they’re skating on sparse ice. And I mean value they’ve waited until all pieces of this technological puzzle receive got fallen inward house earlier addressing the problem. Therefore, a whole novel API inward macOS 10.15 to address the GPU/Nvidia province of affairs makes lots of sense.
Agreed?
