beQUIET

"It is a must-have app for all Macs that will be used in school, library, and public places!" As long as beQUIET is running, your Mac's internal speakers are muted. Meanwhile, you may still listen through your headphone jack. Simpto says, beQUIET only mutes your internal speakers in any condition. beQUIET is designed for journalists, teachers, students, and other Macbook users who want to hear the sound but do not want to disturb others, such as in meetings, classrooms, courts, lectures, and theaters. Benefiting from your Mac's high-end hardware design, beQUIET guarantees that your speakers stay quiet and your headphones work no matter if you plug or unplug your headphones! This App is developed due to the request of a teacher who needed his computer lab to be quiet, but still, let the students enjoy the sound with their headphones. features v1.66 - Check the internal speaker's status and mute them in real time; - Saves and sets the speaker's volume automatically before and after running; - Easy-to-use interface; - Animated menu icon; - No need for any additional hardware; - Headphones' mute status and volume can be freely adjusted; - Feature requests are welcome and lifetime free upgrades; v1.66 -> v1.68 - simple password function added for teachers and parents; v1.68 -> v2.15 - add an option to hide the app's desktop interface - change the exit alert's default selection - status menu bar icons modified for better flashing looking - add "feature request" menu - add "more by dragonBTV" menu v2.15 -> v2.28 - add an option to hide the dock icon - add an option to start at login - add an option to bypass password - add an option to remember the password - add an option to bypass the exit alert - more detailed technical support email templet - more detailed feature request email templet - updated more by the dragonBTV panel v2.28 -> v2.40 important upgrade according to the user's feature request: -add a Fully Customizable Global Hotkey to invoke mute internal speaker or not.
