Hello AlbertS,

The installation of Band-in-a-Box shouldn't have any affect on how other applications on your computer are running as long as you have sufficient hard drive space to run the program comfortably.

However, if you are experiencing issues with Band-in-a-Box on a Sierra OS, you may want to ensure you are running the latest build 146 which you can download and install from here: http://www.pgmusic.com/support_macintoshupdates.htm#2016_146
