I’ve been always annoyed with inability of selecting dialog box on Mac using keyboard like you can in Windows:
Thanks to this rather-old-post there’s actually a way to enable dialog box option selection / cycling using keyboard. Go to System Preferences -> Keyboard and select All Controls under Full Keyboard Access at the bottom:
Keep in mind Return key will always activates the blue button regardless which button has focus. If you want to active the button that has focus (blue border), use spacebar.
Now there’s one less thing for which you shouldn’t take your fingers off keyboard from.
Having GNU Toolchain handy is always a good thing because you’ll never know when you have that urge to “download the source and compile it yourself”. However it took my a while to figure it out the first time I got my macbook air.
A lot of posts and forum threads suggest installing Xcode which come bundled with a set of toolchain, but apparently newer version of Xcode (v 4.4.1 at the time this post is written) no longer installs the binary into the standard location (/usr/bin, /usr/lib and so on) — instead it’s all placed inside /Applications/Xcode.app to fit with newer App Store style packaging. This means you can’t access the toolchain from terminal shell.
Thanks to http://stackoverflow.com/a/9420451/179630, the trick is once you’ve got Xcode installed, go to Xcode > Preferences > Downloads and install the Command Line Tools component.
