Canon DPP on iMac

I've recently bought a new 21.5 inch iMac with 8GB ram and Nvidia graphics card to process my images, prior to this I've always used Windows PCs.

I'm also a big user of Canon DPP software, but on the iMac I've noticed an odd problem.

After processing say 50 raw files (opening them, editing, saving, applying a recipe, etc. but not batch processing) the software suddenly stops working and tells it has "insufficient memory". I have to quit out of it and restart from where I left off.

I've also tried DPP on a 5k retina iMac and it does the same thing after about 50 images. I'm running the latest version 3.14.47 on both Macs.

Canon support tells me it's a hardware issue, but I'm not so sure it is given the problem appears on two independent computers.

Anyone else had this problem with DPP on a Mac? Used DPP for years on Windows and never seen this problem.

    Hi oneill17,

    EDIT: Sorry, I misread the question, in a rush to go out, so removed the misleading post.

  • (Trev, the OP's question regards DPP not PS.) Oneill, if you google DPP insufficient memory you will see that this seems to be a common problem, particularly if there are a lot of images in one folder (there are recommendations to split the folders with smaller numbers of images in each). I think DPP has some memory leak issues, and there is likely nothing wrong with your Mac.

    Dang, sorry, I was in a hurry, and did not read it properly as I was going out, thought he processed in DPP and went to PS, my mistake, thanks.

    Yes, I'd agree with NikonGuy, it does appear to be a memory leak, can you check like you used to on a PC the performance and see how much memory it's using first up, then once you edit some files, check again.

    I would edit less files at a time, a pain in the arse, but probably best.
  • From what I can tell so far, it seems that after editing around 50 raw files in succession the error pops up. I quit and restart DPP and all is well, I can carry on from where I left off.

    The first couple of shoots I edited on the Mac resulted in around 30 jpgs in the final output, and I didn't get the error during the editing process.

    So I guess a memory leak in the software is the issue as you both say.



  • You may want to look into upgrading to DPP 4. I understand it's a complete re-write of the software. Make sure your camera is a supported model, some of the older ones are not with this version.
  • Problem is I shoot on a 60D and a 6D, and only the 6D is supported at the moment.
