We have seen some cases where BreakTweaker encounters a permissions issue due to the default preset save location not having read/write access. Below are some steps to work around this issue in BreakTweaker.
1. Go to Macintosh HD > Library > Application support > iZotope > BreakTweaker
2. In the BreakTweaker folder find the BreakTweaker Library
3. Click and drag this folder to the location below:
Macintosh HD > Documents > iZotope
4. Open BreakTweaker in your host and click on the gear icon to open preferences for BreakTweaker. Under library, location click the “set” button and change the location to Documents > iZotope > BreakTweaker Library, then press OK.
Once completed you should be able to save your BreakTweaker presets to this new location.
