3.3.5 download Mac

Hello, I'm trying to download wotlk 3.3.5 on my new MacOs Catalina version 10.15.... I tried both versions you guys provided but once it downloads and I go to open the wow file, it tells me: "world of warcraft needs to be updated. The develop of this app needs to update it to work with this version of MacOS." Any ideas to resolve this? So eager to play as its been a long time! Thank you!!

that is because MacOs Cataliana does NOT support 32 bit app.

You can downgrade your mac os OR you can run Wotlk for Windows by using CrossOver.
It is software to run windows application on Mac OS.
