After I installed Yosemite 10.10.2 (14C94b) Beta, I have not been able to play Utube videos and other video clips using Safari with out a very low resolution and with out stopping and buffering pauses. The Utube videos show that they are setting up at 140p...not even 1440p. The images are very fuzzy. Prior to this all was fine. I reset the PRAM and still no better. I am not the best technically, but has anyone else seen the same issue and have a tweak here? Otherwise all is good. By the way I have an i5 stock model 5k iMac.
