Hello all,

After terminal frustration with El Capitan's incompatibility issues, I reinstalled Yosemite 10.10.5 on my 21.5" iMac. However, YouTube videos will not play in Safari 10.0.1 citing "Your browser does not recognise any of the video formats available. Click here to visit our FAQ about HTML5 video.".

After clicking that FAQ link I am still confused about how to resolve this HTML5 incompatibility issue. I have installed Safari extensions "ClickToPlugin" and "YouTube5" (among others).I have quit Safari and restarted but without improvement.

Could someone advise me how to get Safari to play HTML5 YouTube videos under Yosemite, please?

Sincerely, PaulRanger2.
