nvidia display driver update

I am running a Late 2013 Macbook Pro with NVIDIA GeForce GT 650M 1024 MB & Intel HD Graphics 4000 1536 MB (from about this mac) on OSX 10.13.6. I keep getting messages on Adobe Photoshop that there is a problem with the display driver and to contact the manufacturer for an update. Which driver is outdated - the NVidia or the Intel, and where would I find the correct updates? I keep seeing Windows and Linux updates on Nvidia site, as well as CUDA drivers for Mac. I haven't looked at Intel side yet.
