Hi Jason, thank you. I installed Catalina on my other macbook and it doesn`t work. Motivewave is fine but the IQ feed client is only 32bit and Catalina is only 64bit. So I have to wait until IQFeed makes a 64bit version client. Hopefully soon.
I contacted the IQFeed team back in February and asked them about the new Mac client. They said - not enough requests from the clients. You may want to contact them and raise your concern. Perhaps, after the new OS release they would be forced to create a new 64bit version.
