I don't really know if there is a good way to get up to speed with the OS, other than just using it. Familiarity will come with experience; At least I've always found that the best way to get familiarized with a new OS (or any software) is to acknowledge that I will probably not be as effective during the inevitable period of adjustment, and try to perform tasks that I knew how to perform with the preceding tool. Here is a short list of various software on my mac I find very useful: - AppCleaner (http://www.freemacsoft.net/appcleaner/ http://www.freemacsoft.net/appcleaner/): Removes files and preferences associated with applications you wish to uninstall. - Amethyst (https://github.com/ianyh/Amethyst https://github.com/ianyh/Amethyst): The only fully functional dynamic tiling window manager I've found that works well under OS X. - f.lux (https://justgetflux.com https://justgetflux.com): Change display color temperature according to time of day. - Moom (http://manytricks.com/moom/ http://manytricks.com/moom/) [or Divvy/SizeUp/...]: Manage, move and resize window with keyboard. - Menumate (http://zipzapmac.com/menumate http://zipzapmac.com/menumate): Trigger menu bar with hotkey. - Shortcat (https://shortcatapp.com https://shortcatapp.com): Goto anything on the screen via keyboard, sort of a fuzzy finder for the UI, - iTerm2 (http://iterm2.com http://iterm2.com): Alternative terminal emulator. - MAMP (http://www.mamp.info/en/ http://www.mamp.info/en/ Apache, MySQL and PHP stack. - Coda (https://panic.com/coda/ https://panic.com/coda/): Very nice editor, particularly for frontend webdev, as it includes page preview functionality, as well as some other tools. Alternatively, your editor of choice. - Cakebrew (https://www.cakebrew.com https://www.cakebrew.com): GUI for homebrew. You should also check out brew cask (http://caskroom.io http://caskroom.io), which enables you to install binaries via homebrew. P.S. As your question is very broad indeed, I think you might get more responses if you asked a few narrower questions or described some specific problem.
