I cannot access the Nik plugins with Photoshop 22.3 either, while PS 22.2 works as expected.
According to DPREVIEW, PS 22.3 has a few limitations…
Meanwhile, I’ve tried a few things and can report that I have the Nik plugins back at work.
Here is how I did it on my iMac (Intel, macOS Mojave):
- Quit out of PS
- Select the plugin folder located at /Library/Application\ Support/Adobe/Plug-Ins
- Press command-I
- Click on the padlock and enter the necessary credentials
- Propagate the rights to all objects (see screenshot)
- Close the Info window and start PS
CAVEAT: Can’t say whether this hack impairs upgradeability of the Nik…
UPDATE: Does not work on MacBook Air M1. Workaround: Open with Rosetta.
