Kepler notebook/mobile GPU list is here:

Cannot find the desktop list right now, but basically is GTX 680 series.
Believe FERMI is completely EOL from NVIDIA at this point. Only maintenance updates, no additional functionality added to drivers or patches. Apple controls their driver in Mojave, so no reliance on NVIDIA as long as native products are Apple supported. The current Mac NVIDIA Web Drivers are basically in "maintenance only mode" so do not think they would be changed/dropped from what is currently supported. This
theoretically could impact CUDA at some point, but if you're running CUDA with FERMI GPUs as your daily driver on Mac there are bigger issues you need to address at this point.
KEPLER mobile GPUs are basically being EOL'd in April 2019. This could
theoretically impact some MacBookPro (and iMac) users with 2013 and prior machines, especially if they run Windows. Unsure if the NVIDIA Web Drivers (that were BETA supported for these machines) will continue to support KEPLER mobile GPUs beyond their current "maintenance only mode" approach in High Sierra and prior. See no reason why they would not continue as-is, but as everyone knows, NVIDIA is not very transparent with their Mac drivers/support plans.
Ultimately, everyone's long-term plan should involve moving to Apple's recommended list for Mojave
at some point. Would also recommend picking up one of the recommended GPUs while they are still being manufactured (personally suggest RX580). High Sierra will not be supported by Apple forever.
