The Mac version is a crippled version (IMHO) of the PC version. I'd used Quicken for Windows for 15 years before I got a Mac, but one look at the Mac version of Quicken and I installed an emulator to run my old Windows OS on my new Mac. This was 5 years ago, but I'm still running Quicken on Win7 on my Mac (but there have been upgrade charges for Parallels and Quicken in the meantime).
At least at the time, Quicken for Mac had no ability to enter ESPP or stock options, so it wasn't useful to me (maybe they've been added since?)
If you still want to try the Mac version, get it on Amazon or somewhere else for $50, not Intuit's $75.
