canon mp navigator ex and Lion not working

When I download those applications from Canon, Apple will not let me open them. Saying MP Navigator ex-206 can't be opened because it is from an unidentified developer. In image capture there is no scanner shown, I've tried turning on and off hoping that it will register it... still nothing.

Because this version of MP Navigator does not have a digital signature, you have to Control-click (or right-click if you have enabled it) the MP Navigator installer and select Open from the menu that appears. You may then get another prompt about this app not being signed, click Open to continue.

If Image Capture does not show the MP630 then there could be an issue with the ICA driver that should have been downloaded from Apple when you added the device. Assuming you have no issue with printing, thus indicating that the physical connection between the Mac and MP630 is okay, then you could try installing the ICA driver from Canon.

Just one more note about the scanner. You will not be able to use the scanner if you have the MP630 connected to another Mac or if you have its USB cable connected to an Airport Extreme or Express.

We have the MG6150 - I can not open the MP navigator, it goes immediatly to an error message. Will installing the ICA driver work with the MG6150? So far anything I am downloading from Canon will not open with Apple. It says its in my security prefereces that I do not want anything opened unless from a trusted source. I do not know how to change this?

Okay. Different models of Canon MP, MG and MX series use different versions of MP Navigator. I incorrectly assumed you had an MP630 since this is what the original poster had.

So for you MG6150, called MG6250 here in Australia, it uses MP Navigator v5.0.2 and v18.0.1 scanner driver. For MP Navigator, select the installer after mounting the dmg file and Control-click. Then select Open from the menu as shown below.

The next window will shown the following. Click Open to continue with the installation.

Hey, I have downloaded them, I am not given the option of opening. It is the same as the message above, but just says OK then closes message. We are in Australia and its MG6150.. not sure if that makes any difference.

This is the message I get when I try to open MP navigator

If you just double-click the installer then you will get this message.

But if you hold down Control and then click the installer, you should see the messages as above.

Well, at least this what happens in 10.8. But I thought that same is available on 10.7.5. If not, open System Preferences and select the Security & Privacy tab. The General tab has entries about what applications can be installed. If you change this to Anywhere, then you can install the application. Note that you will probably need to click the lock in the bottom left section of System Preferences and authenticate in order to make the change. And after installing MP Navigator, revert the setting back to Apple and developers.

As for you having the MG6150, the drivers and MP Nav are different to the MG6250. So please get them from Canon Australia via this link.

Success!! Thank you so much Pahu!! 🙂🙂

Mandy - like I said I went to Canon's web site - did you try that?

I installed all the software (driver and Navigator) and Navigator no longer crashes but I can't see the scanner in Canon IJ Network Scanner Selector EX. I can scan using image capture but not using Navigator EX. Any ideas anyone? I tried removing all the Canon software, rebooting and re-installing, but it still doesn't work.

Just wanted to say that downloading the new ScanGear does fix the issue of a grey preview. It is available here (for the MP980) and is under the 'Drivers' section, called 'MP 980 series Scanner Driver'

I removed all my Canon softare, installed the driver then MP Navigator EX and all works as it used to.

Thanks web-bert that has worked for me ...

I am using the Canon 5600F scanner and it the mp navigator ex doesn't work with lion. Any suggestions on a fix?

I have MP Navigator EX 2.1 and it works fine with Lion. I had trouble at first but sorry to say, I can't remember how I got it to work. But it does work!

My MP Navigator crashed every time after I updated it from Canon. I use an MX310.

I solved this problem.

Go to System Preferences:Print and Scan, choose your Canon printer, on Scan Button, choose "Open Image Capture", and that worked. I'm scanning with Open Image Capture instead of MP Navigator.
