I have an older iMac with OS X 6.8 and an Intel processor. The TurboTax version I downloaded needs at least OS X 7.5 but I don't know where to get that or how to install it.
If you can help, please explain without jargon, I'm not skilled at this (as you have already surmised from the very nature of my dilemma).
Thanks in advance for your thoughts and time.
Mac OS 8.6 or Earlier
Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.
