Things to be aware of
Remember that you must adjust security settings as described in https://zwifthacks.com/zwiftmap-for-macos-is-here/ when you install the application.
Default security setting on macOS complain that Zwiftmaps is from an unknown developer (the app isn’t signed with an Apple-recognized/trusted certificate). Requires going into System Preferences -> Security & Privacy -> click “Open Anyway”
Chat and ride/run data are disabled
Your user probably have insufficient access rights to enable capture of network traffic. You can enable it with the following command in Terminal (it will give your user read access to the network devices /dev/bpf*):
sudo chmod o+r /dev/bpf*
You must also activate Network capture features under Settings in ZwiftMap.
This should hopefully be enough to let ZwiftMap capture network traffic (from next time you start it).
Crash when you start or exit ZwiftMap
If you get a crash window where you can choose to send an error report it is most likely because you have activated Network capture features under Settings in ZwiftMap but not changed the permissions for /dev/bpf* as described above. It is known to provoke program crashes.
