Mac errors Catalina 10.15.5

Downloaded wotlk, getting mac error when trying to launch:
“World of Warcraft” needs to be updated.
The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.

Helpsky?

Mac os Catalina does not run 32 bit app.
That is why.

Here 2 different solutions:
You can use Wotlk for windows by using "CrossOver" (by following this guide http://forum.warmane.com/showthread....=1#post3043338 )

Otherwise, here a different solution: http://forum.warmane.com/showthread.php?t=421912

Thanks skull. I thought maybe someone who have compiled the client could recompile it for 64 bit architecture (if there is one)...
