Since Apple has been using only graphics hardware from AMD and Intel in Macs for years, modern Nvidia chips can only be addressed as plug-in cards in old Mac Pros or via a Thunderbolt eGPU solution. For such solutions Nvidia was able to provide suitable Mac drivers.
For security reasons, however, it has been obligatory for some time that drivers from third party manufacturers must be signed by Apple. Without such a certificate a driver installation under MacOS is no longer possible with one click.
The current MacOS Mojave lacks such a Nvidia signature from Apple
since months. Why Apple withholds this signature is not known.
"We need the Nvidia support - please, please, please". With these words Jarred Land (head of RED) is supposed to have asked Apple publicly and very urgently not to let the Nvidia support die under MacOS during a presentation for 8K video editing.
Whether Apple will be softened by such pleading words remains to be seen. Rumours have it that a dispute about defective Nvidia laptop chips a few years ago and the recall campaign that followed has severely disturbed the relationship between Apple and Nvidia.
On the other hand, a simple solution without Apple would be conceivable: Because in principle it is also possible to install unsigned drivers at
with some manual work. For users who urgently need the driver, Nvidia could make it available unsigned until clarification. But a PR-effective intercession from the Hollywood corner is probably more effective in the end. Especially if a manufacturer doesn&t want to be exposed to Apple&s arbitrariness every time.
Nevertheless, we can&t shy away from a side blow: Under Linux, Nvidia uses
allegedly signed drivers for its own hardware isolation and thus actively prevents open Mesa drivers, for example, from being able to control the clock rate of the GPU or the fan control. One person&s joy, the other&s sorrow.
