Compatibility between Turbo Tax 2025 app and Mac OS 27

Hello -

I have an older M2 MacBook Air that I'm running OS 27 on.

Thus far, the OS and the Apps that I have and use have all be playing nicely.

Until I went to file my 2025 Taxes yesterday.

I use Turbo Tax. And there is a clear problem between OS 27 and TT2025 in the online transmittal area.

It took me four attempts at transmitting my State and Fed returns today. The app ran fine, until the transmittal process and locked up during. Spinning pinwheel and all. I waited 20 minutes, and had to force close each time.

I checked in with Turbo Tax's support who claimed that have been receiving a lot of support calls from MAC OS 27 users suddenly. Which didn't help me, but I knew it wasn't just my own hardware/software situation.

I tried disabling my software firewall, tethering from my iPhone, even creating a new Admin user. Nothing worked.

While I had Apple support on chat, I tried twice more and the second time the transmittal went through. I received an email confirmation from Intuit that the transmittal was successful.

Just wondering if anyone has had a similar experience?

I understand that TT will no longer be compatible with OS 28. The TT rep shared that TT is trying to convince people to go online instead of purchasing the local app to get around this problem. We'll see next year.

Thank in advance!
