## Troubleshooting tips
If you are installing Linphone on a Mac, you must give permission to Linphone to use the microphone after installation. Failure to do so will cause the microphone to not work at all in Linphone, but work in all other applications.
To do so, first close Linphone entirely. Click on Settings, then Security. From the list of peripherals on the left side, select the microphone. If the lock icon on the bottom of the window is locked, click it to access the settings that are disabled. Linphone should be checked. Close the windows and retest.
