Thanks for the heads up. I’ll probably sit out this round of Nik Collection upgrades. I paid last time but still don’t find the plugins particularly useful. I prefer to just do the work in PhotoLab which does work and with far fewer apologies (no hardware acceleration on Mac, very poor performance on images over 40MP are PhotoLab’s principal sins). I’m on 4K screens and am not going to set up a low resolution environment just to use Nik Collection. I’m still tempted to do some work in Silver eFx as the work from others I’ve seen processed there is extremely impressive.
Just for your information. The 4K/HiDPI-Scaling issues persist in Nik Collection 5: https://forum.dxo.com/t/nik-collection-5-hidpi-problem-with-4k-monitors-still-not-fixed/
