Hi there, @D_Perkins_23. I'm here to help you restore your QuickBooks Desktop (QBDT) for Mac company files.
Thanks for sharing the details of your concern. To resolve this, let's first ensure that your QBDT program is updated to the latest release. This will provide you with the latest components and fixes.
Once done, restore the backup. QBDT Mac backup file is in a .dmg format and restoring it directly is unavailable. You'll have to double-click the file to mount it. Once done, drag it from the open window to your documents folder. From QuickBooks, use the file open company and navigate to the file.
Please know that the name of your backup company file also shows the year version of the QuickBooks you're using. For instance, since you use QBDT for Mac 2016, the backup company should be "Your business name.qb2016".
