During many years, using different versions of MacOS ( Yosemite, El Capitan, Sierra, High Sierra, Mojave, Big Sur ) I got this error message upon trying to launch Preview ( and sometimes Safari ):
The application Preview is not open anymore.
I am not yet able to reproduce this bug ( otherwise I would have submitted a useful bug report ).
In the case I am working on now, the error is true: Preview is not open anymore. Neither ps nor Activity Monitor find it.
If I try to start the application with:
open /Applications/Preview.app I get a slightly more intelligent error message:
LSOpenURLsWithRole() failed with error -600 for the file /Applications/Preview.app.
But it appears that in fact this function is deprecated ( from the developer official documentation ).
I am actually working with opensnoop and dtruss to get which process is seeing this application not present and why this could block it starting again.
How may I further debug this blocking error of MacOS?
