With all due respect I put greater trust in Apple than this software which is causing problems for Catalina users. I’m a long-long-term user of Nik and haven’t experienced any problems with it running on Mac OS over the last decade…until downloading this current version. BTW, I paid for this after buying the whole package and upgrades over the years. Not happy. Refund?
What Sigi said. Also, my understanding is that, to request a refund, you must go to dxo.com and navigate to customer support (or just go to support.dxo.com).
When it comes to Catalina bugs, I wouldn’t agree that Apple is much better.
Since macOS 10.15.2, I can no longer use Image Capture to download files directly from my camera via a USB cable. Apparently it is a known bug, which we now have to wait for a fix.
For Catalina (or every huge update) the best way is to do a clean install after formating the drive. It works like a charm here on my old iMac 5k from 2014.
