Got LAME but computer can't open mp3 encoding library

Hi, I’m trying to convert my project to mp3 and have installed LAME but every time I try to save it, I get a message box saying Can’t open mp3 encoding library. Any ideas?

I’m on Mac 10.10.5 and Audacity 2.1.1
TIA

  1. Update to Audacity 2.3.0 from here: https://www.audacityteam.org/download/mac/

  2. Download “Lame_Library_v3.99.5_for_Audacity_on_macOS.dmg” (this is the “32-bit libraries for Audacity 1.3.3 to 2.3.0”)
    by left clicking on the link here: https://lame.buanzo.org/#lameosxdl
    Important: make sure you get exactly this version, there are several other versions on that page.

  3. Follow these instructions to the letter:

  4. Launch (or restart) Audacity.
