Hi @Scott_L1
Welcome to Zwift Forums!
Catalina OS restricts permissions on certain folders. After downloading the new OS, the Zwift app should ask for permission to access the Documents folder. If this prompt was bypassed, the game can’t run properly, and will shut down or crash.
What might be helpful to eliminate variables is to do a fresh install of Zwift on the Mac. To do this, follow these steps below:
Please note : This process will delete all personal bests and any custom workouts, which are stored locally on your computer, unless you back them up first.
To back up your personal bests:
- Open the Finder.
- Open your Documents folder.
- Open your Zwift folder.
- Copy the “cp” folder.
- Paste it on your desktop, or other folder location other than your Zwift folder, so you can find it later.
To back up your custom workouts:
- Open the Finder.
- Open your Documents folder.
- Open your Zwift folder.
- Copy the “Workouts” folder.
- Paste it on your desktop, or other folder location other than your Zwift folder, so you can find it later.
Once you have backed up any files you’d like to save, follow the instructions below to re-download and then freshly install the Zwift app. Doing so will clear away your old install and download the latest version of Zwift onto your Mac. - Open up Finder.
- Select “Applications” from left side menu.
- Locate Zwift app and drag to trash.
- Download the installer from Zwift.com/download and run it.
- Move your backed-up files back to the respective folders they were in before the re-install.
Please give this a shot and let us know if it worked.
