When I started the app on my Mac (BigSur), it asked me to give permission to my Documents folder. It surprised me and denied it.
After that I could log in, but the application doesn’t start.
I deleted the app, I deleted the Zwift folder in the Document folder and I deleted the Zwift folder in the Application Support Folder. I gave the app permission to the Document folder, but still it doesn’t start.
Still I don’t get it how the app knows my login credentials even after reinstall. After the reinstall I see that I’m already logged in, but if I click on “Let’s Go”, nothing happens.
Sorry to hear that Zwift isn’t launching on your Mac, and that’s a tough one.
This article from Apple Support has the appropriate instructions for how to allow read/write access to specific folders on BigSur. Zwift needs this access to both the Documents and Downloads folders on MacOS. Without that access, the app won’t function.
Also, make sure you’ve made the appropriate exclusions for the Documents and Downloads folders in any file sync apps you may use (e.g. GoogleDrive, Dropbox, etc…), and in any firewall apps you’ve installed (e.g. your antivirus).
If you have a VPN or proxy, turn it off as it can block your connection to our servers.
If none of that helps, please send us a support request, and include all of the log files from your Mac. Our tech support team is happy to work with you on this. You can reach us here.

Find the Zwift app and use the checkboxes.
Reinstalling Zwift is a waste of time and bandwidth. Also, don’t mess with the file permissions, as suggested further up. That’s a terrible idea unless you know what you’re doing (and in that case you wouldn’t use the GUI anyway) and completely unrelated to this issue.
Your credentials should be stored in the keychain. Besides Application Support, there should also be a Zwift related directory in ~/Library/Caches that you’d have to delete if you really wanted a completely fresh start Don’t delete the Caches directory itself, as, unsuprisingly, has been suggested by support on this forum in the past.
(I haven’t used Zwift on a MacBook in years, so I’m a bit fuzzy about the exact directory paths.)
