Installing Canon SELPHY CP780/790 driver in Mountain Lion

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 http://pdisp01.c-wss.com/gdl/WWUFORedirectTarget.do?id=MDEwMDAwNDIwNDAx&cmp=ABR& 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!

Regards

Thanks very much for this. I used it on the Lion CP760 driver to get it to work in Mountain Lion and it worked fine. I had to do a restart to get it to work, but there it was, straight away.


For the people unsure about which text they are replacing in the driver, you need to replace the whole section:

----------------------------------

function installationCheck() {

return true;

}

<!-- minimum/maximum target -->

if ( (system.compareVersions( system.version.ProductVersion, '10.7' ) == -1) || (system.compareVersions( system.version.ProductVersion, '10.8' ) != -1) ){

my.result.type = 'Fatal';

my.result.title = system.localizedStringWithFormat('installation_check_failed_title');

my.result.message = system.localizedStringWithFormat('installation_check_failed_msg');

return false;

}

return true;

}

----------------------------------

with

-----------------------------------

function installationCheck() {

return true;

}

-------------------------------------

ignoring the dotted lines! In effect this is just deleting some of the text. On my first attempt I didn't delete enough of the function text and got a Javascript error when I tried to install.
