You have to grant apps on your Mac access to certain features or bits of data, such as the microphone or your location. Normally the first time you load up an app it will ask you to do this, but you can change these settings as appropriate. To do so:

Go to System Preferences
Got to Security and Privacy
Click on the Privacy Tab
Click on the padlock at the bottom and enter your password to unlock

You can then clock on any of the options on the side and tick or untick, depending on which apps you want to have access to which features.
