Hi there, jojoma.

I can see the effort and time you exhaust to exports from my Mac OS Big Sur version 11.6.2 to a Windows file.

Since the issue persists, I suggest contacting our QuickBooks Support Team. They have the tools to pull up your account in a secure environment which we're unable to do it here in the Community. That way, they'll be able to investigate the cause of the problem.

Here's how to reach them:

1. Open QuickBooks.
2. Go to Help, then select QuickBooks Desktop Help.
3. Select Contact Us.
4. Give a brief description of your issue, then select Let's talk, and then choose a way to connect. Phone support may be limited due to volume.

Additionally, here's an article that'll further guide you in managing your business using QBDT for Mac: User Guide. It contains topics about banking, lists, and getting paid to name a few.

Please keep in touch if there's anything else I can do to help you succeed with QuickBooks. I've got your back. Have a great day!
