Hi everyone, I am trying to open several Garageband files that my friend has sent me. We are both on MacBook Pros, both running Catalina, both running the latest version of Garageband. When he sends me a file (via email or WeTransfer), it arrives zipped up. I unzip it, double-click the file to open. Garageband comes up and gives me a "save" popup menu. I click "save" and then another popup comes up saying "the file couldn't be opened". This has happened every time he has sent me a file back, and I have not been able to open any of his files. When I create a new Garageband file and email it over, he can open/edit it with no problems. Has anyone come across this problem before? It is so strange. Many thanks in advance, guys!
