Thanks for reaching out. The issue I am having is that QB for Mac Desktop will not import an IIF file which contains QB payroll data.

When attempting to import QB for Mac Desktop backs up the company data file, but then fails to import the data...or provide an error code...it just backs up and then logs itself out of the company data file. 

Your work-around will not work because you cannot export the necessary data from QB online payroll to .csv file. Detailed payroll information is only available for export via IIF file.

We will be moving away from QB online payroll because of this issue, and the many support issues we have recently encountered from QB. Frankly we don't see the attention to detail when it comes to properly deploying software vs previous years. We were forced to move from Intuit Online Payroll to QB Online Payroll prior to QB working all the bugs out of the code.....which is unfortunate.
