I have an older MAC computer running OS X 10.10 and up until several days ago, I could watch videos that were uploaded directly to the forum with out any trouble. Now, the picture shows as it did before but where the run time used to appear, it just shows 0:00. When I press the play arrow, nothing happens. I am still able to watch the videos that show they are from Youtube without any issues.
Has something changed that is causing this to occur?
As I understand it, Apple is no longer supporting my model which was produced in around 2011.
I am not very computer savvy, so I would appreciate any input .
Thanks,
Don
