I'm disappointed to see that http://www.globaldelight.com/ are discontinuing support for Boom1 and charging users to upgrade to Boom2. In fact their smallprint suggests they intend to charge for Boom3.

As a software developer, it would be against my conscience to charge multiple times for a simple utility that the operating system should have supplied.

So, I am looking for alternatives. Is there any other way to increase the volume on a MacBook?

PS Is it just my imagination, or has the most recent OSX (El Capitan) increased the maximum volume level? Since Boost stopped working, I haven't really noticed a problem watching movies.

  • The problem that I have found with going past the max is that sounds get more distorted the louder you go. Is getting external speakers or bluetooth speakers/headset outside the realm of possibilities? – Allan Oct 28 '16 at 20:06
  1. Try the open source VLC

It can boost the audio by upto 200%. The equaliser let's you boost even further.

  1. You can boost audio in iTunes too. Select the song and press Cmd+I

You can boost audio by another 100% and use equaliser too.

Soundflower and Loopback both offer functionalities similar to what you had in Boom, and the ability to boost the volume, which is what you requested. https://rogueamoeba.com/freebies/soundflower/
