Linda, it does not matter which OS you are using. It seems it may have worked for some users but it also states that TurboTax was going to fix their Server as this seems to be a continuing problem. They have not fixed their Server if that was the problem in the first place.
I have a new Apple Desktop with the latest macOS Sequoia 15.2 and I have the same problem. I have done everything which was suggested and spoke with TurboTax. They blamed it on Apple but if you review these treads on this problem the problem is definitely caused by TurboTax and not Windows or Apple.
I also thought it might be my downloaded TurboTax 2024 software at first so I ordered the CD for another $11.00 from TurboTax directly but it did the same thing, "No Internet Connection". Funny that I can open the TurboTax 2024 and it will download their latest software Updates to TurboTax 2024 (through my Internet Browser) and install them but the next screen for activation states, "No Internet Connection". TurboTax has a big problem and it appears they are not fixing anything. I think this will be my last year using TurboTax.
