I am trying to use both/either of the two apps on my iMac but cannot get them to work. I am running macOS Big Sur v11. I can use Lightroom/Photoshop but occasionally would like to use these. When I open DPP4 it does not see any tiff files only CR2&3 camera files whilst PSP does not open. Is there a fix? I use Canon cameras and Canon printers so seemed logical to use the proprietary apps. Anyone know of a fix? Thanks.
