I guess we need more information before providing you with a definitive answer to your question.
If you upgraded from an earlier version of MC to v2.7 and have Avid assurance then you will need to get in touch with the Avid support department as the BCC filters for your upgraded system will come directly from them. If you purchased BCC from Boris directly or from a reseller for a previous version of Avid and do not have Avid assurance then the upgrade to BCC for your system will come from us or via the reseller.
Currently, we do not have a version of BCC for Avid MC that runs natively on MacIntel but we are close to having that ready. Very close.
