I have an iMac (newer than 2007),and I need to run this year's version of Turbo Tax. I am getting a message indicating that my current OS X, which is 10.6.8, is not sufficient to run this year's Turbo Tax (premier version).

I have tried to download Yosemite and have been unsuccessful. I assume that once I download a new OS, that it will appear in place of the 10.6.8 when I click on the Apple icon at the top left side of my screen and ten click on about this mac. How can I download Yosemite?

    Can you be more specific about how you tried to download Yosemite, and how it was unsuccessful? – Gordon Davisson Feb 4 '15 at 4:01

Check your iMac model and the date.

In About this Mac (here is mine)

macbook air model

Yosemite requires iMac (Mid 2007 or newer)

Log in App Store and get it from there. The download process can take very long time, a hour or more (it is > 5 Gig file), depending on your Internet speed.

Once it is done, find the file called "Install OS X Yosemite.app" and click on it.

If Yosemite does not work for you then get the 10.7.5 (minimum required) for TurboTax 2014.


You can download the Yosemite OS X from the App Store. Once the download is completed, the install application appears in your Applications folder. You can either go to the Applications folder and double click Yosemite and follow the instructions, or go to the Launchpad and click Yosemite and follow the instructions.
