Audacity Forum

I wonder if it's because I recorded the tracks on an earlier macOS and possibly an earlier version of Audacity. But not more than a year old at most. That computer fatally crashed so I'm playing the tracks from a Time Machine backup. I guess I just have to kiss the files goodbye.

They are, that's what confuses me. Thanks though.

Using iMac Catalina and Audacity 2.4.2. When I import my .aup files from my previous Mac there is no audio in the tracks window and of course no sound. Is there a fix for this or are all my older .aup files gone forever? The data folders are intact.
Thanks for any help!
