Apple has recently released OS X 10.11 (El Capitan) as part of a free upgrade available to all Mac OS X users. Avid has not completed qualification of the new OS X 10.11 for all products and strongly recommends customers do NOT upgrade to this OS version until qualification is complete. There are open bugs and known issues with current shipping versions of some of our products that will need to be addressed prior to qualification. Please find the qualification status for each of these products below.

 

Media Composer

  • Support for OS X 10.11 (El Capitan) was added with Media Composer 8.5 (released January 29, 2016).  
  • Apple recently released OS X 10.11.6 (El Capitan) which has not been qualified for use with Media Composer 8.6.x at this time.  Once approved, this article will be updated. 
  • Note: If you upgrade to Mac OS X 10.11 thru Mac OS X 10.11.3, you must uninstall Media Composer. Reinstall Media Composer after you perform the OS upgrade. If you use Avid Artist DNxIO, you must also uninstall the Desktop Video software and reinstall it after the OS upgrade.
