I then configured the MP 640 for WiFi using the Canon IJ Network Tool and after configuring the printer was able to print over WiFi. I also tried using the MP Navigator 3.0 which gave the same problem (could see the device but not use it. There was also a scan tab present but when I clicked on that the program that opened was apparently unable to connect to the scanner. So now I have bought the MP 640 I said I would (a bit more expensive 25 Euros) and attached it using USB to my MBP (running Sierra 10.12.4) and saw when I opened Printers and Scanners saw that it had been automatically configured and I was able to print to it. BTW Still do not see the Device under FotoLader (Image Capture). I am planning to buy an MP640 2nd hand soon as they are being dumped due to not working under Sierra (which I very much doubt). Perhaps I will see some strange behaviour in future but for now it is working just fine.
The Canon site however says that for the MP640 El Capitein is the last supported version that they have downloads and for the MP600R its Mountain Lion.
BTW there is a summary of Sierra supported printers ( ) on in which the MP600R is listed under "Niet meer beschikbaar als software updates" (Software updates no longer available) but the MP640 is listed as supported with (driver ?) version 13.7.1.0. When I accepted the new Printer was configured and I am now also able to scan via WiFi. With that selected clicked on Wijzigen (Change/Modify) at which point, and this is easy to miss, a small window opens asking if you want to allow the incoming connection.
After the update Fotolader (Image Capture) still did not see any devices so I went back into Navigator and clicked on Voorkeuren (Preferences) where I saw the USB printer which I could scan from and the old MP600R (WiFi). As it did not see any devices either and Sierra 10.12.4 was pending I went ahead and installed it, thinking it can't hurt and might help. Tried to scan using the MP Navigator 3.0 but when it didn't see the new device I thought I would try the Fotolader (which is apparently the Dutch name for Image Capture). I configured the printer on USB first and after test printing configured it for WiFi Using the Canon IJ Network Tool which worked fine too. RationalPlan Project Viewer is a free project scheduling software viewer, the perfect solution for anyone (from project stakeholders to team workers) to view your projects in detail.I just purchased a 2nd hand MP600R for 10 Euros (predecessor of the MP640R) as my old one died and with all the stories going around I was concerned that it would not work as I had upgraded my MBP from Yosemite (under which the old MP600R worked fine) to Sierra 10.12.2.
Runs on: Mac OS X, Mac OS X 10.4, Mac OS X 10.5 RationalPlan Project Viewer for Mac v. It helps you to view both 2D and 3D models on MAC. There are different viewing options to help you clearly view DWG files.
Here you can choose to open DWG, DXF, DWF, and DWT files. ZWCAD Viewer is a good freeware that can be used to view DWG files on MAC for free. A cross-platform 3D model viewer FBX® Review software is a stand-alone tool that lets users view 3D models and animations across many platforms without using a 3D authoring tool.
I can't find anything on DWF Composer for Mac OS X either. I called the Autodesk store and they no nothing of it. Is there a DWF viewer for Mac OS X? There was a press release posted on the Autodesk website announcing DWF 6 for Mac OS X, but I can't find info anywhere.
