Greetings, @MikeKe,

Thanks for getting this to our attention and for letting us lend you a helping hand. Allow me to share some insights about upgrading your QuickBooks version.

All QuickBooks editions follow a standard system requirement to ensure it works as designed. Please be reminded that we cannot guarantee that you'll have a trouble-free experience since you're using a non-supported version which isn't compatible with Mojave 10.14.2.

At the moment, you can try saving the file to your Documents or other location and see if it updates there. If the problem persists on the new drive, I'd recommend getting in touch with our QuickBooks Mac Care Support.

There they can share additional workarounds to help you get back on track. Here's how you can contact them:

1. Go to this link: https://help.quickbooks.intuit.com/en_US/contact
2. Choose QuickBooks Mac Desktop.
3. Click the Search for something else button.
4. In the Tell us more about your question: box, type QuickBooks 2012.
5. Scroll down and click the Get Phone Number button.

That should do it, @MikeKe. Please let me know how this goes. I want to ensure you're taken care of.
