@Mook3, Welcome to the HP Support Community! I’m here to help.

Do you get any errors while trying to install the HP Smart app on the Mac?

How is the printer connected?

Check for any software updates on Mac

Click the Apple icon > About This Mac > Software Update and install any available update.

Download the HP Smart app from the App Store.

If this does not help, install the printer using the AirPrint driver

1.) Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners. 

2.) Check if your printer name displays in the Printers list, If your printer is listed, click the printer name, click the minus sign to delete the printer. 

3.) If you see multiple printer queues for the same printer, remove all extra printers by selecting them one at a time, and then clicking the minus button at the bottom of the list. 

4.) Click the plus sign click Add Printer or Scanner, click the printer name. 

5.) Click the Use or Print Using menu, select AirPrint in the pop-up menu. Then click Add. 

Note: Select "Bonjour multifunction" under kind while installing.

Try printing.

Hope this helps! Let me know how it goes.
