Prevent app from opening Open File window

Okay, found it. Either disable iCloud Drive or open its options and disable Preview, TextEdit, QuickTime Player etc.

That's because it doesn't know which file you want to view. The only way to prevent this is to open the file and if Preview is not the default, then right-click and from the menu choose Preview. The same is true with TextEdit and many other apps.

Nothing you can do about that Preview open file panel in El Capitan unless you wing it with AppleScript.

Dock : Launchpad : Other : Script Editor.

tell application "Preview" to activate

Click the run > button to see what I mean.

Save as an Application to your Desktop as (e.g. JustPreview).

Substitute Quick Time Player for Preview in the script.

Ok, this script was run 10 times in a row, and every single time, it removed the open panel from the screen. There simply is no means to prevent the open panel in the first place.

Replace instances of Preview with "QuickTime Player" for that application.

tell application "Preview" to activate

tell application "System Events"

delay 1

tell process "Preview" to click button "Done" of window 1

end tell

return

tell a

FWIW, nothing pops up when I open Preview. TextEdit either.

I should say TextEdit opens with a new blank document.

I have "Close windows when quitting an app" and "Ask to keep changes when closing documents" enabled in System Preferences > General. I don't know if that is the difference.

You're welcome.
