System 7 Sounds on Mac OS X

Updated on July 24 2020

Sounds in Finder
Mac OS 7 (1991) stored sounds in the resource fork of files or applications. Back then you could use ResEdit to access them.
File Juicer extracts sound resources into one sound per file, and you could listen to the extracted sounds in Finder (until about 2012). Finder's "Column View" was the most convenient if you had many sounds.


  • Mac OS 10.4 to macOS 10.13. Catalina no longer runs 32 bit apps.
  • File Juicer 4.36 - the last 32 bit version of File Juicer
  • If the file stores the resources in the data fork, make sure it has the extension .rsrc so File Juicer can identify it

File Juicer 4.36 also creates a QuickTime 7 version of the same sound, without reencoding to preserve the quality. QuickTime 7 is not compatible with macOS Catalina

You may find QuickTime 7 here: QuickTime 7 search on You will need it to play the old .mov files as QuickTime can't handle them today.

Convert the Old .mov Sounds With File Juicer 4.36

Make sure the AIFF box is checked in File Juicer's preferences. Then drop in the .mov files extracted from the files you originally had the sound in. Like text files made by SimpleText.

Convert and Organize Sounds with iTunes (2010ish)

Sounds in the resource format (of type 'sfil') used before Mac OS X are no longer the most convenient format. To convert the sounds to AIFF, which has much better support by MacOS X (Mail, Alert Sounds etc), you can switch iTunes import preference to AIFF, drag the QuickTime version of the sounds (made by File Juicer 4) into your library and convert them in this way.
Importing in iTunes After the import you can drag the sounds back out to the Desktop or into your Library > Sounds folder, where Mac OS X will recognize them as system sounds.

Remember to switch the import setting back to your regular setting after converting the sounds!

Converting Sounds to AIFF with Automator (2010ish)

If you have Mac OS X 10.4 "Tiger" you can use this iTunes Import As AIFF "droplet" application to import into iTunes without the need to adjusting your preferences. It imports the sounds into an Album called "AIFF Imports" so you can easyly find the imported sounds in one place.

You can open the "iTunes Import As AIFF" application with Automator to see how it works, and change the Album title if you desire.
