So I eagerly updated to Yosemite when the version was released on the apple store. First impressions are good up until I plan to watch some netflix. I usually do a lot of multitasking so I use a matrox dualhead2go to get my main monitor on my laptop and two monitors above. However, when I start netflix with the externals connected, I get a "Display error...Make sure monitors are HDCP compliant and not Airplay Mirroring." I saw some members getting this error when Yosemite was in beta but no one has responded with a solution. However, I would like to add that this set up worked perfectly on Mavericks using the external monitor. Any update on the issue from any members? Is this something I should report to apple? Do you think this will be fixed in an update or is this something embedded into Yosemite forever? Hopefully theres an answer out there that can revert the settings so it worked when it was on Mavericks. Also worst case scenario, would I just need to revert back to Mavericks? EDIT: forgot to mention, I have a 2012 cMBP 13"
