Please see screen shot attached for "Save file for accountant" feature, which indicates that the file can be opened by Quickbooks for Windows.

I have used this procedure previously, as well as "Export... To Quickbooks for Windows." Both procedures invoked the "Verify step" (optionally), and both produce what appears to be the same QBB file as output. The files are the same type (the icon says "WIN.QBB") and size. 

The "verify" step fails in both scenarios, and as the original question, and mine, was what to do about this, I consider that question still unanswered. 

Thanks.
