Hello, chrissyh123.
Being constantly bombarded by updates every single time can be irritating as a software user myself. I'm here to help you fix the app so you can open it without interruptions.
It looks like the automatic updates didn't apply properly, which is likely the reason why it keeps telling you to install a new version. To fix this, you'll want to uninstall and reinstall the QuickBooks Online Mac app.
Simply drag the QuickBooks app from the Applications folder to Trash. To completely remove it, go to Finder then click Empty Trash.
Download the latest version here.
You can also use this article as a reference if you need help installing it: Install the QuickBooks Online for Mac app.
