Get your taxes done using TurboTax

On a Mac, simply quit and reopen TurboTax. If there are any updates, you'll be prompted to download them.

OR With your desktop program open, go up to the very top left corner of your Mac screen. Next to the little apple---click on TurboTax and then choose "Check for Updates" from the drop down menu.    Here's an old screen shot, should be in the same place or similar.
