Murmure should ask for permissions to access your microphone and accessibility.
Restart Murmure for the permissions to take effect.
> [!IMPORTANT]
> Updating Murmure on macOS from 1.6.0: If you experience issues with Murmure and the shortcuts are not working, please do this exactly in this order, (and "Remove" means not only un-toggling but really removing completely Murmure from the list) :
Remove Murmure from System Settings → Privacy & Security → Accessibility.
Remove Murmure from System Settings → Privacy & Security → Input monitoring.
Install the last version
Launch Murmure.
Re-grant the Accessibility
Re-grant the Input monitoring permission
Restart Murmure.
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.
MacOS - Intel (Official)
Download Murmure_x86_64_darwin.dmg from the release page
Drag Murmure to the Applications folder, then open it from there.
Murmure should ask for permissions to access your microphone and accessibility.
Restart Murmure for the permissions to take effect.
The same upgrade note from 1.6.0 applies. See the MacOS section above.
CLI Import (1.8.0)
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.
fix(macos): Reopen the main window when the Dock icon is clicked, closing the window only hides it so the click did nothing and the menu bar entry was the only way back to the UI (thank you @linkermaxx) https://github.com/Kieirra/murmure/pull/439
fix(audio): Restore the output streams that were recreated or started while dictating, browsers drop and recreate their stream when tabs change so the restore missed them and the audio server kept the lowered level for the whole application, which made every new tab start at that level
fix(transcription): Turn the hesitation sounds cleanup into an option, off by default, the list is stripped whatever the language so it also deletes real words such as the German "um" https://github.com/Kieirra/murmure/issues/445
fix(macos): Explain in the Show in Dock setting that keeping the Dock icon hides the recording overlay over full-screen apps, macOS ties that switch to the activation policy and a Regular app cannot join the Space owned by another full-screen app whatever the window asks for https://github.com/Kieirra/murmure/issues/437
fix(overlay): Set the collection behavior on the recording overlay at creation time on macOS, only the window level is set today so following Spaces works by default rather than by design https://github.com/Kieirra/murmure/issues/437
feat(cli): Add a --quit flag to close Murmure completely from the command line, the tray menu is the only way today so tiling WM users have no keyboard path https://github.com/Kieirra/murmure/issues/429
feat(overlay): Keep the overlay on screen after a dictation with the transcription and a copy button, plus a thin bar showing the time left before it hides, so you see what was written when the paste landed nowhere and you can read the result of a command without pasting it, no focus detection needed so it works on the three platforms https://github.com/Kieirra/murmure/discussions/443
feat(settings): Add an automatic insert option next to the text insertion mode, to keep an insertion method (Ctrl+V, Ctrl+Shift+V, Direct) while turning off the automatic insertion of the transcript https://github.com/Kieirra/murmure/issues/449
fix(api): Remove the experimental tag and consolidate the API
fix(api): Implement LLM Connect service
Backlog
feat(updater): Opt-in setting to subscribe to beta (pre-release) updates
(under consideration) feat(draft): Draft Mode to review and edit a transcription before writing (medical use case)
(under consideration) fix(packaging): Authenticode-sign the inner murmure.exe on Windows, not only the installers, so the app runs under Smart App Control (needs a second SignPath submission before bundling) https://github.com/Kieirra/murmure/issues/428
