Hello s-majumdar,
Yes, the PIXMA MP620 is compatible with the Mac OS X 10.6.8 operating system. If you need updated drivers for the printer, they can be downloaded from the Canon USA website. The following link will take you to the initial download page for your PIXMA MP620:

Once on the initial download page for your model, please do the following:
1. Select MAC OS from the "SELECT OPERATING SYSTEM" drop-down menu, then please use the "SELECT OS VERSION" drop-down menu to select the OS X v10.6 SNOW LEOPARD version of the operating system. (You may need to scroll down in the list to find the drivers for your operating system).
2. Next, please click on the red arrow next to the "DRIVERS" section and click the file that you would like to download. You will want to download the CUPS, ICA, SCANNER and MP DRIVERS FOR NETWORK drivers. When you do, another page will appear giving details of the file you are about to download will appear.
3. Please scroll down on the Details page and agree to the terms of the disclaimer message to continue with the download process by clicking on the "I AGREE - BEGIN DOWNLOAD" button. After clicking the "I AGREE - BEGIN DOWNLOAD" button, follow the instructions to download and install the driver. The time for the download process may vary depending on the speed of your Internet connection and the size of the file being downloaded. Please be sure to have the USB cable unplugged from the computer prior to installing the drivers; the installation program will prompt you to plug it in at the appropriate time.
Hope this helps!
