Welcome to the Community, mtitcombe.
Thanks for taking the time to post your question. I want to make sure you're able to use your QuickBooks Desktop for Mac and the My Time app together.
To make sure both platforms are operating at their best, you'll want to make sure they have both been updated to the latest version. The following links provide the steps to update:
Additionally, you'll need to save a backup copy of your file when downloading newer versions: Back up your QuickBooks Desktop for Mac company file
If everything is already updated and My Time still won't sync with QuickBooks I recommend reaching out to the My Time Support Team to take a closer look at the connection issue.
Please feel free to reach back out here if you have any other questions or concerns.
