Hi there, 

Is anyone familiar with how to easily save a JPG image with CMYK color (as opposed to RGB)? Thanks!

Easily is a relative term ;

Gimp is strictly a RGB editor. There is an application + python plugin that will convert your completed RGB image to CMYK. 

https://github.com/rodlie/cyan/releases/tag/1.2.4

I do not know if the OSX version works with your installation, I use linux where it looks like this: https://www.gimp-forum.net/Thread-CMYK-c...0#pid16030

Other ways:

Use the krita graphics application as a converter http://www.krita.org
There are online converters. https://www.rgb2cmyk.org
ImageMagick https://imagemagick.org command line can convert magick <rgb_file.ext>  -colorspace cmyk -profile <icc_file>  <cmyk_file>.jpg

Edit: These days printers (as in printing companies) are more relaxed about file type. They most probably will accept your RGB image with a warning that some colours - bright blues, greens will change and become subdued. For photographs, the latest commercial laser printers will deliver excellent quality. Ask your printer.

You can also use the development version (https://www.gimp.org/downloads/devel/) 2.99.14 to import and export CMYK JPEGs. There's still no CMYK mode yet, but you can soft-proof the image with your printer's color profile and color-pick/match in CMYK format.
