**HDCP Errors iTunes\Safari fix**


Symptoms:
*You had to reset the PRAM on your Mac for whatever reason
*iTunes movies won't play. You either get a black playback window or an error related to HDCP.
*Hulu and Netflix movies won't play within the Safari browser.
*YouTube is unaffected by this.
*Hulu and Netflix still play within Chrome web browser.
*Windows 10 (VM nor Bootcamp) are unaffected by this bug


Fix (workaround):
*Boot into Recovery Mode on your Mac (command+R)
*Open terminal and type in the command EXACTLY as written:


nvram 8be4df61-93ca-11d2-aa0d-00e098032b8c:epid_provisioned=%01%00%00%00


and then press RETURN


It will go back to the prompt. Type reboot and RETURN. 


Use this information at your own risk. If this sort of thing makes you uncomfortable, perhaps you should contact Apple support directly and have them walk you through this.


If you have to reset your PRAM again for any reason, this will have to be done again in order to restore functionality. Apple is aware of this and will likely provide some sort of update to perminantly fix this.


This is truly a workaround, not a fix. But it should provide you a fully functional Mac in the mean time


If this does not work for you. Please try this again and triple check what you have typed. This command is case sensitive and it will NOT throw up an error or success message to let you know the result.


Good luck and good day.
