> [!IMPORTANT]
> Murmure requires the Microsoft Visual C++ Redistributable to work on Windows. This package is present on most computers, but if you encounter the error message The code execution cannot proceed because MSVCP140.dll was not found. Reinstalling the program may fix this problem., download and install the package from the official page or use this direct download link: https://aka.ms/vc14/vc_redist.x64.exe
> ⚠️ Antivirus Notice : Some users reported that Kaspersky may block Murmure. If needed, please add Murmure as an exclusion in your antivirus settings.
Make it executable: chmod +x Murmure_amd64.AppImage
Run the AppImage.
> [!IMPORTANT]
> Murmure currently has limited support on Wayland-based distributions (except Fedora, which can fall back to X11 for some apps).
This appears to be related to Wayland’s sandbox restrictions for AppImages, the global shortcut to start recording will not work in this environment.
No workaround is available yet. See #28

> 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.
