How can I grant mi­cro­phone ac­cess?

Mac Format - - GENIUS TIPS - by Pa u l Y o u n g

QI have a game that in­cludes a voice chat fea­ture. Since up­grad­ing to Mo­jave, that fea­ture doesn’t work. I had ex­pected it to show a di­a­log ask­ing to use the mic, but that never ap­peared. How do I add the game to the list in Sys­tem Prefs?

AMo­jave’s new pri­vacy pro­tec­tion puts strict lim­its on what apps and users can do. It stops apps ac­cess­ing mics or cam­eras with­out first ob­tain­ing your con­sent us­ing a stan­dard di­a­log; if you agree to that, macOS adds the app to the re­spec­tive list in the Pri­vacy tab of Sys­tem Pref­er­ences’ Se­cu­rity & Pri­vacy pane.

Although you’d nor­mally add apps your­self to the Full Disk Ac­cess or Ac­ces­si­bil­ity lists in that pane, you can’t do so un­der Mi­cro­phone. An app has to re­quest that it­self in or­der for you to be in­vited to give con­sent. The rules for how apps must do this are quite com­plex, and de­pend on which ver­sion of Ap­ple’s de­vel­op­ment sys­tem was used to build them.

First, check for an up­date to the app, or whether sup­port in­for­ma­tion on the game’s web­site has been pub­lished ex­plain­ing how to ad­dress this in Mo­jave. If you’re us­ing the lat­est re­lease and there’s no ad­vice, con­tact the game’s de­vel­oper and point out the prob­lem. Un­til they ad­dress it in their app, it won’t be able to ac­cess the mi­cro­phone. Only the de­vel­oper can fix this.

You can’t make changes to the app it­self to in­flu­ence its be­hav­iour for ac­cess­ing hard­ware. Do­ing so would change its con­tents, break­ing its code sig­na­ture. Gate­keeper then wouldn’t al­low you to run that app.

When first run on Mo­jave, apps like GarageBand prompt you to con­sent to them us­ing the mic or cam­era.
