Ratings and Reviews
Very good idea
Good idea now that the volume bar cannot be selected and dragged to be controlled in Sierra (since it’s gone from vertical to horizontal). The only negative is that clicking the icons at the very top of the desktop is no longer possible… I tend to throw my mouse cursor up to the top and click, but now you have to hit a few pixels down from the top to be detected. Fix that (and maybe use the stock volume control icon instead of the bar used in the app) and I’ll change my review to 5 stars!
Works but missing some features
This app works just fine but there should be an option to set the scrol direction i.e. natural vs reversed. As newer MacBooks have natural scrol direction, so you expect scrolling down on a tackpad should reduce the volume however it increases it. It will be good to have the option. Also sometimes the on-screen notification does not disappear after you finished adjusting the volume. Otherwise app works fine.
With Family Sharing set up, up to six family members can use this app.
