How do I download the desktop version of Quickbooks Self Employed for Mac? I have just the online version now.

Hi there, @jmooreland-gmail.

QuickBooks Self-Employed (QBSE) doesn't have a Mac version. You can only install this app to your IOs devices or open it on the web. 

If you can access App Store on your Mac device, simply search QBSE to install the app. 

You can also open the App Store menu using this link: https://apps.apple.com/us/app/quickbooks-self-employed/id898076976

For the web version, click here to access QBSE: https://quickbooks.intuit.com/self-employed/
 

Moreover, mileage tracking is a built-in feature in QBSE that will help you track your business miles. To get more info when using this feature, check out this article: Automatically track mileage in QuickBooks Self-Employed.
