Hi, the desktop app we use on our iMac is not working properly. we cant save then exit a invoice or quote or create new products, lots of things are not working?

Let's try a few basic troubleshooting steps for this, coolsparkare.

You can reset the app. It optimizes your QuickBooks experience.

1. In your QBO, click Help at the Top.
2. Then, select Reset App Data.

Another option that helps you sort this out is to uninstall and reinstall the app.
