Software Upgrade on iMac 2012

Trying to download current version of Turbo Tax. Says I need to be on version 10.14 or higher. I have a 27 in iMac Late 2012 on version 10.13.6 High Sierra. What is the most current version I can upgrade to?

iMac 27" late 2012 running 10.13.6 can run Mojave macOS 10.14, and tops out at Catalina macOS 10.15.


That iMac cannot run the current release.

Mojave macOS 10.14 is the last version that runs 32-bit apps. Catalina requires all apps be 64-bit. That means upgrading from Office 2011 to Office 2016, Office 2019, Office 365, or the upcoming Office 2021, for instance. Upgrading or replacing or retiring all other 32-bit apps, as well. You can see your 32-bit apps using the Go64 tool, among other approaches.


If you're on a deadline right now, go with Mojave.


Have a backup or two created prior to the upgrade. The backup is the only reasonable path to recovery, should there be a problem with the upgrade.
