I'm using OpenSSL 1.1.0 and I'd like to roll back to the previous version. I'd like to uninstall the version I have currently installed on my mac, but the instructions in the Make file are really ambiguous and Im a novice when it comes to this kind of stuff. I posted the uninstall instructions below. Am I looking at this wrong? This doesn't look straightforward.
