I have an iMac (about 2 years old) running El Capitan v 10.11.2. Since about two weeks ago Sky Sports will only load as a small screen and cannot be adjusted to large screen view. Also, none of the other controls on the Sky Sports window work either. (i.e. volume control, change channel etc). I have the latest version of silverlight installed.
Many thanks for your reply. I am using Safari and, as far as I can tell, no updates are due for the iMac. On the plus side, I installed Firefox today and can, once again, after a lot of fiddling around, watch Sky Sports!
However, it is frustrating as I would still prefer to use one browser and have got very used to Safari. I have tried uninstalling and re-installing Silverlight, scoured the Sky community for an answer but constantly am getting nowhere. Sky Sports worked fine up until recently and I am not aware of any updates, but they might have occurred by stealth!
In summary, any suggestions would be welcome, but please do not take too much trouble. At least I can watch again, even if it is not perfect.
Thanks again for your reply. I have just checked the cookies and they are on Always. I think it must be something to do with Silverlight as all my other Virgin TV on demand works absolutely fine on Safari. Am completely baffled....!!
