How can I maximize a window in Finder without using third-party software? I read this post but none of these tricks seemed to work.

    Many of those tricks are third-party appellations which would work fine. What problem did you have?

Move the mouse to the corner of the window where it becomes a resizing arrow and option double-click to fill the screen.

A double-click on any side or corner will move that side/corner to the edge of the screen. Adding option will affect the opposite side as well.

  • More details: double click on any side to move that side to the edge of the screen, and add option to affect the opposite side as well. Aug 9 '20 at 6:03
  • That is brilliant! All these years and I never knew that! I've added your comment to the answer.

  • I have been using Apple computers since the Lisa, and I found the shortcut a couple of days ago on this page: news.ycombinator.com/item?id=24091707, but the poster didn't really realize what it could do. Aug 9 '20 at 11:35

I bought Moom by Many Tricks to solve the Finder's inconsistent zoom behavior. Get it from their website for a free trial and 60-day money-back guarantee. It's been a great solution for me, not just for the Finder problem, but for all my work on a 30-inch Cinema Display.

  • It's on the App Store as well, no trial of course. BTW, I personally think Moom is the best of it's genre. You should make it the first one you check out.

  • Buy Witch ( manytricks.com/witch ) while you're there. It finally makes Alt+Tab work properly.

  • So there is no way doing this without a third-party application?

  • Don't think so, but Moom is really, really good. One of those apps that should just be integrated into the OS. Sep 21 '11 at 23:33

  1. Launch /Applications/Utilities/AppleScript Editor.app and turn on the preference: General » "Show Script menu in menu bar"

  2. In Terminal, type or copy/paste

    mkdir -p ~/Library/Scripts/Finder

    cd ~/Library/Scripts/Finder

    curl --remote-name http://dl.dropbox.com/u/18414/ase/MaximizeWindow.scpt

  3. Go to Finder, open a new (non maximized) window

  4. In the menu bar, look for the the "Scripts" item, then look for Finder, and then MaximizeWindow

Select that, and Voilà!

p.s. - please note that I am not the original author of that AppleScript. I found it at http://olivierfabre.com/shortcut-to-maximize-the-finder-with-applescript and simply tested it and found it worked really well. It appears to be designed with hard-coded values for the screen-size, but if it can't make the window that big, it simply maximizes it.

p.p.s. - the scripts menu isn't all that convenient, but there are ways to assign keyboard shortcuts to them, etc. If you were not averse to 3rd party solutions, I would immediately recommend FastScripts and mention that it is free for up to 10 scripts :-)
