Hi, jannatbeautydesigh,

Thank you for choosing QuickBooks Desktop for Mac.

At the moment, we're unable to integrate Square to the Mac version. What I can suggest is to connect your bank account to QuickBooks. That way, when your Square payments are posted in your bank, they will be downloaded to Bank Feeds and you can add them to your register.

On the other hand, I will bring this idea to our product engineers to let them know that you need this option for your business. We've made improvements to QuickBooks based on users' feedback and suggestions. This could be added in the future.

We have articles for QuickBooks for Mac in the Community. You can use them as a reference in the future.

You can always keep in touch with us if you have questions as you use QuickBooks. More power to your business!
