I have read Intuits support entry of 10/25/14 which says "QuickBooks for Mac 2014 and earlier versions may run on OS X 10.10 (Yosemite), but are not supported at this time. We won't take steps to prevent customers from installing QuickBooks, but know that some features may not run correctly in this environment. Earlier versions of QuickBooks were designed and built to run on the Mac OS version that was available at that time and not Mac OS X 10.10."
I recently upgraded to 2014 from 2011, and sooner than I had planned upgraded machines to a new Retina laptop running Mavericks. It's Yosemite-ready and the *only* thing holding me from upgrading OS is Quickbooks. 2011 received numerous updates over the years; have 2012 and 2013 also? I'm trying to divine what might occur regarding 2014 and Yosemite; the statement above seems to foreclose that possibility. I don't need and cannot justify annual $250 application upgrades.
