Hi,
I found Francis Fustier's article for installing the BU-353 on a Mac. This article is old but it contains a link to download the Prolific PL2303 USB driver for macOS 10.13.

It may help if you told us what version of macOS you have and what other application (software package) you are trying to use with the BU-353 in addition to OpenCPN.
Here is the official Prolific download site for their driver on macOS 10.15:

Prolific added this special note on the installation for macOS 10.13 to 10.15:
"NOTE: Mac OS High Sierra 10.13 introduces a new feature that requires user approval before loading new third-party kernel extensions. Go to System Preferences - Security & Privacy and click Allow."
