As with with Prolific drivers for Windows, the Prolific company
intentionally crippled their device driver so it won't work when
paired with a counterfeit Prolific USB-to-TTL chip. Genuine Prolific
chips in programming cables are rare. Out of the 20+ programming
cables I have that are detected as having a Prolific chip, only 1 is
genuine. It cost $25 because the vendor specifically went out of his
way to source these programming cables with genuine Prolific chips.

Like Windows users still can, Mac users can no longer use the old
generic drivers that are shown on the MacOS Tips page (which used to
be the workaround Lion, Mountain Lion and Mavericks) because they are
not signed. You either have to spend $9.11 and get the signed,
3rd-party device driver (which provides functionality with programming
cables having PL2302 (Prolific), CH341 and CP2102 chips) or put the
$9.11 toward an FTDI chip based programming cable that allows you to
use the native Apple driver.
