Get your taxes done using TurboTax

there is nothing Intuit can do if you're on MAC OS 13, support for that OS ended last Nov and Intuit does not support Turbotax on unsupported OS versions.  If your hardware is not allowing upgrade MAC OS 14 that means your hardware is outdated also.

 

The solutions are either find/buy a different laptop that is supported (Win 11 or MAC OS 14 or above), use online (a different experience tho - no forms mode, only 1 return, tends to be more expensive tho Intuit has an offer this year to move a desktop license to use Online Premium Fed+State), or use alternative s/w - HR Block is your only option in the desktop space which is still supporting older MAC OS versions.
