OK - I just downloaded the new sling plug in to my Mac Pro 10.7.5, because I was forced to. I just found out it doesn't work with 10.7.5. All of my computers are running on this OS and it was working fine before the upgrade. Can I revert back to the old plug in? I really don't want to replace my 2 Mac Pros.
Unfortunately you are unable to revert back,but we do have an option you can try that does not require a plug in. Below is a link to an embedded player which you can download and may be able to use instead of watching on the website.
Hope this helps!
