I'm having problems with Turbotax 2011. I installed the application on my iMac i7 running OS 10.7.2. The application after it was installed and started advised me there were updates to the program. On going for the updates two screens came up the larger one indicating it was installing update #1. Then a smaller screen comes up and say's it's D/Ling the updates. The smaller screen keeps repeating itself over and over again without any real progress. I had to foce the application to be able to access restart. The smaller screen stays on the screen until the restart. If you choose not to do the updates the program will run and you will be able to input info from your 2010 Turbotax and place other info into your tax form. The Turbotax people are aware of this and are convinced it has to do with the update to 10.7.2. I tried it today and it was still doing the thing as I described it!
