Apple claims Netflix needs to Update
I just completed my Apple Tech call this morning: it took 65min to eventually hear Apple blame Netflix as cause of problem and nothing could be done on Apple's end -- no foreseeable OS update to resolve the issue -- and actually suggests that Netflix update their platform to meet Yosemite OS.
Netflix, of course, blames Apple. Netflix's solution is to download Chrome or Firefox (bypass Safari) for Yosemite OS Users. Apple Tech confers with this solution and suggests download of Chrome for immediate success.
Also, in my opinion, Apple Customer Service has diminished their reputation. They didn't deal with the issue straight on, but, instead, chose to run the Customer thru bogus ineffective "solutions" and act like this is the first they've heard of the issue; hard to believe.
The best solution Apple Tech could advise is very simple and honest: inform the Customer straight away that it's now known that Safari on Yosemite OS is not compatible with Netflix at this time, so for immediate satisfaction, download Chrome or Firefox browser.
