Title: OS 9 with sound on Mac Mini (and perhaps more?)
Post by: jackoverfull on March 21, 2026, 11:24:37 AM

Where did the Mac OS 9 on Mac Mini G4 topic go?! Oh well…

As you know sound is stuck to impossibly low levels…Or so it was, thanks to  matouspikous/    MacLegacyLabs and some IA vibe coding!

Here to download the extension: http://macintoshgarden.org/apps/macmini-audio-fix

Seems to work perfectly on my Mac Mini.
I wonder if it works on other unsupported systems too and on lower OS versions.

For this interested, I suggest checking out the TECHNICAL.txt file in the original GitHub repo that explains the cause and solution:

THANK YOU SO MUCH!

I can confirm that it works on both Mac Mini 10.1 and 10.2. I also tested it on an iMac G4 1GHz (GF4) and it works perfectly.
