Hi there, @Madcap.

I appreciate you coming back to us for additional support. Allow me to join this thread and share some more information.

You're correct. For the iCloud sharing to work properly, make sure to only access one file. In your case, you have to select and update the desktop file (with more transactions) and continue using it, then rename the other file to avoid confusion.

That should do it, Madcap.

Let me know if you have follow up questions by adding a comment below. I'm still here to help you further with QBMac. Have a wonderful day ahead.
