I noticed the following issues when I updated Nik Collection 4.1.1 to 4.2.0 on my M1 MacBook Air:
Dialog button too small in localised installer
No Photoshop Plug-Ins!
Installer cannot be ejected after installation
- rebooted the Mac and ran the installer again. This time, Photoshop was recognized, the plugins were installed and seen in Photoshop. Note that I had reinstalled PS from scratch and not used it before launching the Nik installer. Nik seems to look for something else than the photoshop app…
