I've Googled for this a little bit, and I wasn't able to find an obvious answer, so is it possible to hide the Finder sidebar completely? So that it never comes back until I tell it to? The same goes for the toolbar.

Thanks for any help you can provide. :)

Extra info:

  • I am using OS X Mountain Lion on this Mac.

Hide it just for a certain window? Or for all future windows? Or for all windows created in the past as well? – GEdgar Oct 13 '12 at 21:42
I would like to hide it for absolutely everything, no matter the day it is, or was, open. – greduan Oct 13 '12 at 21:43

defaults write ShowSidebar -bool false; killall Finder

ShowToolbar -bool false didn't seem to work.

Thanks for the answer. :) So this would make it automatically never appear again? – greduan Mar 21 '13 at 13:24
Yeah, but it doesn't seem to affect some special folders like trash. – user495470 Mar 21 '13 at 13:39
I see. Thanks again! – greduan Mar 21 '13 at 13:45

Open Finder, both options are in the View menu.

View -> Hide Sidebar

For the Status bar,

View -> Hide Status Bar

I've tried that, but it appears again by re-opening the folder. lol BTW, I don't want to hide the sidebar. – greduan Oct 13 '12 at 22:27
ahh, odd functionality. creating an new window in Finder using cmd+N opens a new window with the Sidebar hidden, but opening a new window by double clicking opens a new window with the sidebar... odd – Stu Wilson Oct 13 '12 at 22:30

Use FinderMinder. In preferences check Run AppleScript, click edit and add this line

set toolbar visible to false

New Finder windows in Mountain Lion appear to behave as in previous versions:

Create a new Finder window in any manner--Command-N, click on Finder in dock, etc. Adjust this window as to screen location, size, view style--everything customizable. Close the window -- and all future new Finder windows will be exactly as you have set.
