How do I open lots of Preview windows on macOS Monterey?
I have about 30 pdf files, and I would like to open them all in Preview, one per window. I can bring up Finder, then click on each pdf file. For the first 14-15 files, each click brings up a new window, just as I want. But after that, each click just opens the clicked file inside the last Preview window. Why is this, and how can I get around this limit?
I'm running macOS 12.4 (Monterey) on a MacBook Air. I am logged in as an Admin user, my normal login. For comparison, I tried opening new Finder windows, and got to about 35 before I got bored and stopped. Also, my Preview preferences include "When opening files: Open each file in its own window". I ran "ulimit -a" and the limits there seem very generous. I also ran "open -a Preview *.pdf" on a command line, and got the same result (after closing all of the existing Preview windows). I even logged out as myself, and repeated the same experiment as Guest (not Admin); same result.
