it should work. It's a bit painful but you will not do it again with the next version, it's because 1.6.0 have the same name but is not detected as the same application... so macos is lost.

2. Drag Murmure to the Applications folder, then open it from there.
3. Murmure should ask for permissions to access your microphone and accessibility.
4. Restart Murmure for the permissions to take effect.

The same upgrade note from 1.6.0 applies. See the MacOS section above.

Murmure supports importing a .murmure configuration file via the command line (murmure import config.murmure), useful for mass deployment or sharing settings across machines. A --strategy merge option is available to keep existing settings. See the CLI documentation for details.
