Enabling access to my Documents folder in my Security and Privacy settings after upgrading to Mac 10.15 Catalina fixed the issue for me.
However, I strongly feel that this shouldn’t be required. There is no reason Zwift needs to be able to read all of my Documents. My Documents folder contains personal information, and I shouldn’t have to give Zwift access to it. Is there any way a different folder could be used? Downloads could be slightly better (but not much), but a directory that only Zwift has access to would be best. This is a notable security/privacy concern and degrades my trust in Zwift as a user.
Thank you for your consideration!
