I don't use Macs regularly at all and need port a screensaver from windows to Mac. I've successfully made .app file that runs as expected on OSX.

On windows I can just rename an .exe to .scr and install/run it. Is there a process in OSX to do something similar with my .app file?

  • Please provide more info. What have you done so far "successfully"? To partly answer your question: sometimes OS X will respond desirably to renaming file extensions. Depends on what you're trying to do. Did you make a .app file with automator or Xcode? Documentation on screen savers developer.apple.com/library/mac/search/?q=make+a+screen+saver . Also, if you go here in Finder on your computer HDNAME>SYSTEM>LIBRARY>SCREENSAVERS you can see the (three for me) types of screensavers currently used by OS X and their extensions. – NOTjust -- user4304 Dec 24 '13 at 4:38
  • By the way, technically, a .app is a directory. – SamB Aug 4 '14 at 17:39

Why not use the built-in OS X Screen saver functionality? For example http://osxdaily.com/2010/04/30/make-a-screensaver-out-of-your-own-images-in-mac-os-x/

If you wish to write a screensaver app, this article is a good start: http://cocoadevcentral.com/articles/000088.php
