# Product Name:
# Neither of the above solutions provide the OS 'product name' (e.g. Catalina, Mojave, High Sierra etc.)
# So I curl Wikipedia's macOS version history page and parse out the name.
#
# The problem in doing so is that I need a version number (e.g. 10.15) 
# but the version number provided by `sw_vers -productVersion` is the full version (e.g. 10.15.16)
# meaning we need to strip the last segment (this is done with the following bash trick: `${version%.*}`)
# also when grepping for the product name it comes up twice in the Wikipedia page, so I use `uniq` to remove duplicates
