I would like to know how do I install the brazilian keyboard into macbook air, keyboard with accents (Portuguese Language), I tried so many times how to put into it (Macbook Air). So, thanks for now! I'm waiting for it.

System Preferences > Keyboard > Input Sources

Then add the Brazillian keyboard on the left.

After you go to system preferences/keyboard/input sources as suggested by sberman, click on the + button and scroll down to Portuguese and select that. Over at the right you will see the choices Brazilian, Brazilian abnt, Portuguese. You might want to add all three to see which you like best.

The "Brazilian" layout is pretty useless. It is identical to the US layout and the only way to make accents is via the option key shortcuts: option + n, then o gives you õ.

The Brazilian abnt and Portuguese layouts have dead keys for adding accents over at the right edge of the keyboard. But these may not match what is printed on your keys.

You may prefer to stay with the US layout. On that you can get accented letters by just holding down the base letter and selecting what you want from the popup menu that appears. Or you can use the option key shortcuts.

Another option is the layout called US International PC, which has accent deadkeys on ~, ', etc.

Which ever layout you want to use, you must select it in the "flag" menu at the top right of the screen.

To see which key does what for any layout, use the Keyboard Viewer:

I realize this reply might be two years too late, but I find it's impossible to install the Brazilian keys. It's best to memorize the following pasted below. If you want to make the tilde, for example, you would press control, then n, then remove both fingers from both keys and type the vowel you wish to accent. Same goes for the other accents.

[Option n] = tilde (til) e.g.: não

[Option `] = grave accent (crase) e.g. Fui à escola. (I went to the school)

[Option e] = acute (acento agudo) e.g.: café

[Option i] = circumflex (acento circunflexo) e.g.: você

[Option c] = cedilla (cê cedilha) e.g. força (strength)

You really should not have any problem doing that. You just go to system prefs/keyboard/input sources and use the + and add buttons to add the Brazilian ABNT2 keyboard. Then select it in the "flag" menu at the top right of the screen. Then you can make all the accents without using option keys.
