Just echo what others are saying; after upgrading to macOS Big Sur none of my Canson and Hahnemühle profiles are visible in the soft proof adjustment. This is a major issue for me and others that are printing for their businesses.
I did the below troubleshooting which unfortunately didn't resolve the issue, hopefully it might help the Affinity team tho;
- Removed and reinstalled Affinity Photo (from the AppStore).
- Removed and reinstalled using trail download from Affinity Photo site.
- Checked permissions on /Library/ColorSync/Profile which was all OK.
- Tested an already existing second login account on my Mac.
- Removed and re-added icc profiles.
- As a test I downloaded new icc profiles.
- Created a brand new admin account.
- Safe boot.
