I’m using the “Systran Dashboard Translator” to translate any sentences.

It’s free.
When I bought my Macbook pro, it was already in it.

I also have the translation software I bought
but
“S.D. Translator” is more than enough.

It’s really easy to use.

First,
Copy the sentence.
Second,
Push the “F12” key.
Last,
Paste the sentence into the “S.D. Translator”

Since it works well in my machine,
Macbook pro is the comfortable dictionary.
