What is “Show desktop” keyboard shortcut in Mac OS X?
I am using a MacBook Pro with Mac OS X 10.5. Is there a similar function to "show desktop" (shortcut is WIN+D) on a Mac?
It should hide all applications and show a clean desktop.

am using Homebrew to install packages on MacOS Sierra or Mac OS X. I noticed multiple version of bash or curl installed in /usr/local/Cellar/bash/. How can I delete an outdated version of brew packages and only keep the latest version on my system?
First, open the Terminal application. To see if multiple version of curl packages installed, enter:
$ ls /usr/local/Cellar/curl/
OR
$ brew info curl
Sample outputs:
curl: stable 7.51.0 (bottled) [keg-only] Get a file from an HTTP, HTTPS or FTP server https://curl.haxx.se/ /usr/local/Cellar/curl/7.50.3 (367 files, 2.6M) Built from source on 2016-11-02 at 03:13:19 with: --with-nghttp2 /usr/local/Cellar/curl/7.51.0 (368 files, 2.7M) Built from source on 2016-11-08 at 01:10:09 with: --with-nghttp2 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/curl.rb ==> Dependencies Build: pkg-config ? Optional: openssl ?, libidn ?, rtmpdump ?, libssh2 ?, c-ares ?, libmetalink ?, libressl ?, nghttp2 ? ==> Options --with-c-ares Build with C-Ares async DNS support --with-gssapi Build with GSSAPI/Kerberos authentication support. --with-libidn Build with support for Internationalized Domain Names --with-libmetalink Build with libmetalink support. --with-libressl Build with LibreSSL instead of Secure Transport or OpenSSL --with-libssh2 Build with scp and sftp support --with-nghttp2 Build with HTTP/2 support (requires OpenSSL or LibreSSL) --with-openssl Build with OpenSSL instead of Secure Transport --with-rtmpdump Build with RTMP support ==> Caveats This formula is keg-only, which means it was not symlinked into /usr/local. macOS already provides this software and installing another version in parallel can cause all kinds of trouble. Generally there are no consequences of this for you. If you build your own software and it requires this formula, you'll need to add to your build variables: LDFLAGS: -L/usr/local/opt/curl/lib CPPFLAGS: -I/usr/local/opt/curl/include PKG_CONFIG_PATH: /usr/local/opt/curl/lib/pkgconfig |
The cleanup option can remove all installed or specific formulae, remove any older versions from the cellar. Also, old downloads from the Homebrew download-cache are deleted. Simply type the following command to free up disk space and delete outdated older versions:
$ brew cleanup
Sample outputs:
It is recommended that you run cleanup after update to get rid of old packages:
$ brew update && brew upgrade && brew cleanup
At the end you will see the following message on screen:

There are several ways to view your desktop in Mac OS X: the most straight forward approach is to manually minimize all windows to the right side of the dock (Cmd+M), or to hide them behind their app icon on its left side (using the Cmd+H keyboard shortcut). But you then need to manually restore all these windows, which will quickly become tedious. There's a better way!
On older versions of OS X, it's one of the Exposé keys. Starting with OS X 10.7, Exposé has been replaced by Mission Control.
The default is F11. On a MacBook you will have to press fnF11, as the keys are used for controlling volume by default.
Note that F11 will not work if you have a full screen window on screen (like the browser in full-screen mode), you will have to switch to the Desktop mode first (using F3, for example) before using F11.
If that's not the right one, look in your System Preferences to see which one it is.
