Hey there,

I just figured out a way to install the new Canon SELPHY CP780 driver from the Canon site in Mountain Lion. This driver from March 2012 doesn't install on OS X 10.8 so you need to fiddle with the installer package.

Here are the steps to install this printer driver on Mountain Lion:

1) Go to lang=EN and download the printer driver

2) Double click the cp780-790os-x-06.dmg file

3) Open a new Finder window so you can see the new device "cp780-790os-x-06" in the sidebar.

4) Open the device by clicking it

5) Copy the file "SELPHY CP series Printer driver_6.0.0.21.mpkg" to your desktop by dragging it with the left mouse button.

6) Click the file "SELPHY CP series Printer driver_6.0.0.21.mpkg" on your desktop with the right mouse button and chose "Show contents"

7) Double click the directory "Contents" in the new Finder window

8) Right click "distribution.dist" and chose "Open with.."->TextEdit

9) Change the first function "installationCheck() so it looks like this:

function installationCheck() {

  return true;


10) Press CMD-S to save the changes.

11) Double click the file "SELPHY CP series Printer driver_6.0.0.21.mpkg" on your desktop to execute it

The installation should work now.

HTH somebody!
