Hello @bpike,

Let's perform a few troubleshooting steps so you can get back to business and work with QuickBooks accordingly.

To start with, let's install and make sure to download the latest released version of QuickBooks for Mac. Let me show you how.

1. Go to QuickBooks.
2. Select Check for Updates.
3. On the pop-up window, select Install Update.
4. Click Install and Relaunch.

But if you're still unable to open and work well with the program even after following the steps above, consider manually updating QuickBooks with the steps outlined in this article: How to keep QuickBooks for Mac up-to-date so you always have the latest features and fixes?

Hello, @PCLG.

There are two possible reasons why you're unable to open QuickBooks on your device. Let me guide you in updating your QuickBooks to get you up and running.

• An obsolete operating system
• You are using an old version of QuickBooks.

Here's how you can update it:

1. From the QuickBooks▼ dropdown, select Check for QuickBooks Updates.
2. If a newer version is available, select Install Update.
3. When prompted, select Install and Relaunch.
4. When the update is complete, QuickBooks for Mac automatically opens.

You can read through this article for more detailed steps: Update QuickBooks for Mac to the latest release.
