When I was going through the security settings on my Mac - something I don’t do on a daily basis - I noticed that PDF Expert had privileges for Input Monitoring (as the only application on my machine btw). After reading what this meant, I removed the privilege. And so far without any impact it seems.
Does anybody knows why PDF Expert should/would have this setting enabled? Especially the part “even while using other apps” worries me a bit. Or at least makes me suspicious.
