I have multiple Quicken Files, each containing different accounts. Some banking, some brokerage, some credit cards. In the Windows version of Quicken I can open any of the files and update the accounts online - All with the same Quicken Account ID. I am contemplating converting from QW to Q MAC 2017 (testing now). I see that each of the converted files required a Quicken ID to set up (I used the same and only one I have). Now when I update them, it tells me the ID is already associated with a different file. It let's me proceed with a warning that the other file will no longer update. When I return to the other file, the same behavior. It works, and I do not update all the files daily, but it is cumbersome and takes extra steps that the Windows multiple files do not need. Is there a workaround for this? Does Quicken expect me to have a different email (the username) for each file? I have about a dozen. Something illogical about this. (As it is the lack of the 2 line register is a problem for my many files). Would appreciate any insights.
