problem with DPP after update to MacOS Mojave

[Helene]

I recently updated to MacOS Mojave and encountered a very strange problem in DPP4. I cannot throw images into the trash anymore. I did give the DPP4 application permission to control my computer in the privacy and security settings. I updated DPP to version 4.9.20, but it did not make a difference. All the other features seem to work. Has anybody any idea how to solve this peculiar problem in the software?

I do not have that problem with my installation - DPP 4.9 and Mojave.

Hi John,

Thank you for your reply. It makes the problem even more mysterious 😉 

All the best,

Hélène

Hi Hélène.

Do you have multiple user accounts on your Mac, such that DPP was authorized by the main account but a second user account has different permissions?

Hi John,

No, I haven't. I have tried uninstalling Canon Utilities and DPP completely and reinstalling it (removing all preference files etc. The universal uninstaller from Canon also does not work with Mojave), but the problem remains. I have no idea what is going on here. I am now thinking of going back to High Sierra. Mojave seems to make my system extremely slow as well.

All the best,

Hélène

Hi,

I just wanted to let you know that I solved the problem by completely erasing my harddisk and reinstalling all the software. DPP4 now works normally again and I can put images in the trash again. I am not sure though this is a solution I would recommend...

All the best,

Hélène

I have the same problem.  I contacted Canon and reported the problem, but they said no one else has reported this problem.  I also cantacted Apple and they said it wasn't Apple's problem; it was Canon Software.  Please contact Canon and report this problem.  I also discussed it with Apple and they said if I am having this problem, other people are also having this problem-Apple said Canon has to solve it.  Canon said that version 4.9.20.0 is the most recent version.

What happens if you try to delete the file directly from the folder rather than through DPP?

Hi John,

That works OK, but it is an extra step.  It is much easier to right click on the picture and move to trash.  That's the way it use to work on the latest version before mojave.  Thanks for the input

I wanted to see if it was a problem with the actual file. I had a problem once where something prevented me from moving a file to trash; I forget the solution, but it doesn't matter since thats not your problem.

I understand with the feeling about finger pointing, but I have DPP 4.9.20 and Mojave and don't have that problem (I just verified it). 

That must mean there is a third factor involved.

Maybe if you used an uninstall app and then reinstalled that would clean up something thats hanging around.

Helene above resolved her problem with a clean install of OS, so it would seem its not a DPP problem. What if you tried re-installing Mojave as an update (w/o cleaning disk)
