OT: Is there a kind of F5 on Mac?

[Colin Holgate]

That’s different. Relaunching Finder would be the same as relaunching the Windows explorer window. What’s being asked is how to you get a Finder window to reconsider the list of files it’s showing. That should never be needed, but sometimes it does seem slow to react to changes of files on a server.

I just found this page:

http://hints.macworld.com/article.php?story=2009091413423819

(you may have to answer a survey question to read the whole page)

On that page is shown this AppleScript, and a link to an app that uses that script:

tell application "Finder"
  tell front window
    update every item with necessity
  end tell
end tell

I didn’t test it as a script, but I have the app installed. Can’t be sure if it’s doing anything. Here’s a discussion page, that includes a link to download the app:

One thing to note, you install the app by dragging it first to Applications, then command-dragging it to the Finder window tool bar area.
