Hi leflerls,
We recommend installing the latest drivers from the Canon USA website to get the printer connected via USB cable. Prior to installing the drivers, we recommend resetting the printing system on your Mac. To do this, please follow these steps:
1. Choose Apple menu > System Preferences, then click Printers & Scanners.
2. Hold down the Control key as you click in the list at the left, then choose “Reset printing system” from the menu that appears. After you reset the printing system, the list of printers in Printers & Scanners preferences should be empty. If your printer is still listed on the left select your printer and then click the minus (-) button to delete it.
3. Restart your Mac.
Once the printing system has been reset, please click here to go to the Drivers and Downloads page for the PIXMA MX922. Once on the page, please do the following:
1. Verify that the operating system detected in the "OPERATING SYSTEM" field is correct, and if it is not, please click the drop-down menu to select your operating system. Please note that you may need to scroll up or down in the list to select your operating system.
2. Next, below the red box labeled "RECOMMENDED DOWNLOADS", locate the CUPS file, then click the SELECT button to the right of the filename. When you do, a dark gray DOWNLOAD button will appear; below that, a checkbox will be shown asking you to agree to the terms of the disclaimer to continue with the download. Please click in that checkbox to agree to the terms. When you do, the dark gray DOWNLOAD button will turn red. Please click on the now red DOWNLOAD button; the file will start downloading. The time for the download process may vary depending on the speed of your Internet connection and the size of the file being downloaded.
Once you have downloaded the CUPS driver file from the website, please also download all other items from the RECOMMENDED DOWNLOADS, DRIVERS and SOFTWARE sections of the webpage. You do not need to download the Canon IJ Network Tool from the SOFTWARE section since you will not be using the printer wirelessly.
Once all items have been downloaded, please double-click on each of the items on your Mac to install them, starting with the CUPS drivers file.
