Safari 15 cannot open Xfinity stream on the iMac

Firefox will not work for xfinity streaming on my MacBook Pro--message says my system is not compatible, but all systems are newer than what is stated to be the minimum requirement. Of course Safari 15 isn't working at all for xfinity streaming. 

I have have the same issue since I upgraded to Safari 15.  xfinity worked with me and came to the conclusion that it is a Safari issue. I have tried all the fixes I can do for Safari to no avail.  The problem needs fixing.  Please....

Safari v15 was pushed out to my MacBook Pro running Big Sur v11.6 on Tuesday, Sept. 21.  My Xfinity streaming personal home page, which had been working earlier that day, would not load but hung at the "Now connecting to your entertainment experience" message.

We also have an older MacBook Pro running Catalina v10.15.7 which still uses Safari v14.1.2 and Xfinity streaming works fine on that.

I was able to install Chrome (v94.0.4606.54) on the Big Sur machine and got Xfinity streaming using that browser.

Just a guess but I suspect that the issue has something to do with the introduction of tab groups into Safari with v15.

Well that was short lived Worked on FireFox for one day now it say what the other person said I don't meet system requirements. Any other work arounds Im going to try on windows parallels and if that don't work go to back up and go back to before update and see if that works 

Don't know how much help this will be but I have Parallels on my iMac which lets you run windows on a mac. I think it cost like $99.00 a year. I already have it so there's that. But Xfinity stream works fine on Parallels. That being said so did Firefox yesterday so I think there's

a free trial not sure. Anyway hope this helps someone. 

I downloaded a free App in the Mac App Store called "Friendly Streaming" and its working for me now. All other browsers did not work, Safari, Firefox, Chrome etc. 

Its not Xfinity its apple last update big sir and catalina does not stream Xfinity. Switch browser to google chrome runs no problem. Called Apple they told me use google 🤪. That tells me they are going to merge ios with mos because in ios it runs everytime

i have the same problem. Been talking to Xfinity on phone forever!!!! No help. I have talked with at least three techs

So many of us have the exact same problem and have talked to both Xfinity & Apple. Two giant companies who would rather play the blame game rather than solve the problem. Some of the best techies work for Apple & yet they are unable or unwilling to take a look at their customer feedback after launching Safari 15 which is almost certainly the culprit. Very disappointing to say the least.

Same issue here.  I did find that Firefox (currently v92.01) is working.  I also have a vitual Mac machine running MacOS 12 Monterrey Beta 7.  Same problem there.

Update:  Firefox stopped working.  My suggestion below (which someone else posted also) is still working.  So, I just dropped it in my Dock and I click that.  I use my MacBook Air 2014, as a TV screen for business news during the day, when I'm working on my iMac.  So this really ticked me off.  I did use the direct website broadcasts of the providers, and that worked.

I reloaded latest Big Suf from Apple Site and got Safari 14.6.2 after load. I did not update Safari to 15 and everything works fine. I can now get into Xfinity TV streaming without any issues. 

Same problem here ... was just chatting with Xfinity support but they offered no solutions ... didn't even seem to be aware that it was a problem

Glad it's not just me! It's driving me crazy. I'm in the Apple Beta program, so I'm reporting this!

Same problem ... I was just chatting with Xfinity support and they seemed unaware it was even a problem.

Xfinity is full of it I have called at least 4 times chatted online and if you read all the posts many people on here have called . There tech support read from a book if its not in the book they are not aware of it.
