Is there a technical reason why 4.0 will not work with Catalina?
Given it requires Big Sur, it basically means I can't run it on my laptop since Big Sur does not run on my laptop.
[EDIT]
Nevermind... I build my own version from source and it works fine on Catalina now.
Keep in mind, however the downloaded compiled version does NOT! You have to re-compile it to work with Catalina.
