Well Parallels seems to think that you can run Windows QB on a Mac: https://www.parallels.com/apps/quickbooks/

As a software developer, I cannot imagine why QB would need to access such low level Windows API calls that Parallels cannot emulate. This is not some graphics intensive application that needs to access the GPU RAM - it's an accounting package. 

I've used Parallels to run MANY Windows applications (MS Office, Tableau, etc.) without any issue.

It's becoming clearer and clearer that Intuit doesn't really care about their Desktop users - you can't sign up for a new subscription, but they are happy to take our annual fees as they push everyone else to the Online version.

At this point, I don't really care if the online banking feature works or not. I just want to clear the Transactions List.
