To download the latest version of the MacOS edition of Praat, click once on the following disk image file:
After downloading, your web browser might open the .dmg file directly; you will then see the program Praat or Praat.app. If your browser did not open the .dmg file, then you should double-click the .dmg file in the Downloads window (or in the Downloads folder in your home directory); after double-clicking you may see the program Praat or Praat.app directly, or you may see a disk icon called Praat6040, which when you open it will show you the program Praat or Praat.app. To install Praat, just drag the program Praat or Praat.app to your Applications folder (or anywhere else).
To start up the Praat program, just double-click it. If you use Praat for the first time, choose Intro from the Help menu.

To protect you against harmful software, MacOS enforces increasingly severe security measures, initially trusting only apps that you downloaded from the App Store. This is a good thing, but it does make it increasingly difficult to start up reliable applications that you download from outside the App Store, such as Praat. Your Mac can throw a variety of messages to you:
If you want to see good-quality phonetic characters on your screen and in your clipboard, you have to install the Charis SIL and/or the Doulos SIL font. These fonts were created by the Summer Institute of Linguistics. To install them, first download the archives:
Then unpack the .zip files, if your web browser has not already done that. This will give you folders called CharisSIL4 and DoulosSIL4. When you open these folders, you will see TrueType fonts such as CharisSILR.ttf, CharisSILB.ttf, CharisSILI.ttf, CharisSILBI.ttf, and DoulosSILR.ttf. Drag these five fonts to the /Library/Fonts folder in the top folder on your hard disk, if you have write access to that folder. Alternatively, you could put the fonts in the Library/Fonts folder in your home folder, although other users of your computer cannot use them in that case.
Sounds are recorded into a buffer whose size you can set with "Sound recording preferences".
The best way to produce pictures is to use the clipboard or "Save as PDF file..." in the Picture window. Both the clipboard and "Save as PDF file..." produce PDF pictures. Most word-processing programs newer than 2006 accept such PDF pictures, at least on the Mac; if you use Microsoft Word 2008 or later, make sure to save your document as a .docx file, because if you save it as a .doc file, Word will convert the inserted PDF pictures into mediocre bitmaps.
To run Praat from a terminal window, write a Praat script and specify that script on the command line, optionally with arguments, e.g.:
/Applications/Praat.app/Contents/MacOS/Praat --run playsinewave.praat 377 0.9
For details see Calling from the command line in the Scripting manual.
