old QT7 allowed conversion (export) from mp3 to mp4
I have 10.8.2 and I saved a copy of QT7 (7.6.6) so I could do conversions such as mp3 tp mp4.
A friend has a system configured like mine. He does NOT have a copy of OT7. He has QT 10.2. We tried to download from Apple the correct app. It won't let us instill a copy on his macine. HELP! Thanks, -bill
