Can’t import company file from Windows to Mac

I have both QB Pro Desktop 2016 for Windows and QB for Mac 2016. I am trying to convert my Windows company file to Mac. I opened the file in Windows and selected the option to copy the file for Mac. The message came up saying it completed successfully. Then I went to QB for Mac and tried to import the file. It went through the whole conversion process but at the last step where it says it’s saving the file, an error pops up: “NSInternalInconsistencyException”. Any idea how I can fix this??? Help would be very appreciated!

Can’t import company file from Windows to Mac

Thanks for alerting me about this error prompt, @mystereons41.


Are you trying to convert your  company file from QB Pro Desktop 2016 to QB for Mac 2016 (vice versa)? If yes, the error you’ve received is caused by round tripping.


To convert your Windows company file to a Mac, here’s how:

  1. Update QuickBooks Desktop for Windows to the latest release.
  2. Open the company file in QuickBooks Desktop for Windows.
  3. Re-sort lists.
  4. Rebuild and Verify your company file data.
  5. Create a copy of the company file.
    1. Click the File menu.
    2. Choose Utilities.
    3. Select Copy Company File for QuickBooks Desktop for Mac.
    4. Save the file on a separate file/folder location with the extension MAC.qbb.
  6. Restore the file using QuickBooks Desktop for Mac.
    1. In the No Company Open window, choose Browse.
    2. Search for the file you want to restore.
    3. If the file is coming from an external drive, create a copy on your device.
    4. QuickBooks will ask if you want to restore a QuickBooks Desktop for Windows file. Choose OK.
    5. Type in a name for the restored.
    6. Click Save.

If you’re still prompted with an error while trying to import the company file, let’s restore a backup (.dmg) in QuickBooks Mac.


If the error persists, I’d recommend reaching out to Technical Support team. A specialist will be able to look up your account securely and further assist you via remote access session.


Here’s how you can reach them:

  1. Click this link
  2. Choose the QuickBooks Product.
  3. Select your QuickBooks Desktop version.
  4. On the Contact Us page, select a topic.
  5. Click on Get Phone Number button to see the support number.

Thanks so much for your reply. I did all the steps in the first section except I did not re-sort lists or rebuild and verify the company file data. Would skipping those two steps cause this error? I will try it again tonight with these steps included.
