Looking for a diagnostic opinion
I am using a Late 2015, 27 iMac, 4GHz I7, 16GB RAM, SSD.
I had the motherboard replaced some time ago, not sure if that is relevant.
The problem, (s), The Auto masking function in Capture one 21 will only partially work and some time ago I was getting blocky artifacts and delays in rendering when working with Topaz Denoise AI 60 MB Tiff files in Capture one.
When I Quit Capture one from the Dropdown Menu I regularly get a message that "Capture One quit unexpectedly, do I want to report it?" not a routine shutdown.
What I find strange is that when I was using Lightroom I used to get a similar message.
I have a 2018 Quad core 2.3 MacBook pro with Capture One installed and everything runs without a problem including C One Automask etc.
I would have thought that an iMac of my vintage should still be able to handle what I am asking unless I have a graphics system problem in the making.
Would anyone have an idea as to what might be going on?
