Hi All,
Decided to take the plunge on Yosemite with Quickbooks 2014 (QB2014). First I installed Yosemite on my 2014 MBA and then installed QB2014. I was able to successfully open my back-up file.
Encouraged by the MBA trial, I installed Yosemite on my late 2013 rMBP where I had been running QB2014. From what I can tell so far QB2014 works without issues.
I would encourage others to try as well. That said, I think it is unfortunate that Intuit does not have a place on their website stating what products will work with different operating--in particular Yosemite. I can't be the only person asking this question.
Cheers,
Don Barar
