Bc_desktop stopped working in MacOS Safari, POSSIBLY across OOD 1.7 upgrade

It appears Apple has made safari near draconian with cross site stuff; the noVNC tab that opens shows errors redirecting to our in-domain SSO app, viz:

[Error] Cross-origin redirection to https://shibboleth.arizona.edu/idp/profile/SAML2/Redirect/SSO;jsessionid=ondbvq9lo3pb15u8enxls91cz?execution=e1s1 denied by Cross-Origin Resource Sharing policy: Origin https://ooddev.hpc.arizona.edu is not allowed by Access-Control-Allow-Origin.

Any suggestions on config changes to placate safari?
