Download photos from some older digital cameras
Photopc is a library and a command-line frontend to manipulate digital still cameras based on Fujitsu chipset and Sierra Imaging firmware. The program is known to work with older Agfa, Epson, Olympus, Sanyo and Nikon (at least CoolPix 900, 950 and 8x0 but not CoolPix 600!) cameras.
To install photopc, paste this in macOS terminal after installing MacPorts
sudo port install photopc
