Hi, all, and happy new year. I have a 27 inch mid-2011 iMac running 10.12.2 Sierra.
Lately, video playback has become a nightmare. Facebook videos start to play then stop after a few seconds with the player citing an error and unable to play video. General other videos can be jumpy and laggy. Interestingly YouTube videos seem to play fine. Could this be the sign of a dying graphics card?
