I ran into the issue detailed here: https://www.kvraudio.com/forum/viewtopic.php?p=8520150#p8520150
I'm trying to understand.
One Kontakt specific issue I've isolated is that the help here says:
Browse for Files: This option will ask you to locate each missing file manually, one at a time, via a file selection dialog. During this process, the name of the currently searched file will be displayed in the title bar of the selection dialog window. (bold/italic my emphasis)
Note, however, in the screenshot, no such display is shown!?
Also, note that the Missing Content file indicates, e.g., "<<<Shreddage3_Stratus_0.nkx>>>", however, in the Mac search window, I see no way to open/select that container.
