SOAP-UI 5.1.2 hangs on MacOS at startup. (Macbook Pro)? When is that fixed?

I get the same issue, but adding -Dsoapui.browser.disabled=true to the vmoptions.txt file does not help.

My java error log is below;

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
