MP Navigator and High Sierra

[Mike12]

After installing macOS 10.13.1 (High Sierra) MP Navigator EX 4.0 has ceased to work.

I have a pixma MG5320 printer and I have tried all the different scanning software options stated previously for MP Navigator.  None of them have worked.  All I get is folder with a read me text, I do not get any upgrades, even going down to Maverick.  I am able to scan directly from the printer using a USB memory stick which is cumbersome but is the only work around I have figured out.  Does anyone have any idea about my model printer.  Thank you.

I have seen those Readme files you are talking about and if you look up at the top of the folder you will see the application file. I missed it a few times myself, but then noticed it up there in the top center of that window. Hope that works for ya.

Thanks McFountain
It worked for me too.
I have a scanner that would not work at High Sierra.
The scanner is old but works great, it is a CanoScan 9000F.

I can now use it again!

A month ago I bought a Canoscan 9000F Mark II and indeed, it's a very good scanner, even for diapositives or negatives. It would be strange that Canon wouldn't support a scanner that I bought a month ago.
The problem here is the software MP Navigator X that causes problems under High Sierra. Strange that we have to go back to an earlier system to get this program work.
There is also a twain driver which allows you to scan from within Photoshop, Acrobat and other twain-compatible apps. This way of use don't give any problem.

I also tried some of the suggestions in this thread. I have a Pixma MG5350 and suffered the same issues, until I got a fix that worked for me.

I have two iMacs, both running High Sierra 10.13.2, but got different symptoms on each machine, when trying to open MP Navigator. When searching for MP Navigator 3.1.5, I installed this TWAIN driver (more in desperation than hope):

This didn't work with MP 3.1.5, so I re-installed MP 5.0.4, and MP Navigator finally opened up, but I still had trouble finding the device.

I tried deleting and re-installing the printer/scanner in System Preferences (don't select the default, search for a new printer) - on my old iMac the printer options were "Bonjour Multifunction" or "Canon IJ Net" - I selected the latter which worked. (I've had issues with Bonjour before). On my other, newer iMac "Bonjour Multifunction" worked.

A lot of trial and error, but hopefully this may be able to help someone else!

I installed High Sierra and the scanning function of MP Navigator no longer works on my Canon MX420 printer.  Are there any driver downloads or patches that I can access to fix this?

Thanks.

There are 12 pages of discussion, many giving work arounds for your problem. I got my MC 870 to work by installing MP NAv 3.1.5. Read the many pages before your post for directions on how to find this and load it.

Canon still hasn't fixed the problem and seems to not care. Don't buy Canon until they get the message that support counts.

I read all the 12 pages and tried some of the work arounds but they did not work for my .MX420. Thanks for trying, Canon certainly hasn’t,

Disappointing Canon.  Ill remember this the next time I need to purchase an electronic device.

MP560 with mac high sierra.

I managed to get my MP990 fully functional with High Sierra.

The trick was to install the MP Navigatro 3.1.5 version mentioned earlier and rename it in the program folder from "3.1" to "3.0".

After that initiating the scan from the printer worked again as before.

IMHO Canon uses a simple mapping from the printer model (i.e. MP990 in my case) to the MP Navigator Release number (here 3.0). So maybe this works for other printer models as well.
