Starting with macOS Sierra (10.12), any application distributed outside the Mac App Store runs from a randomized path. So the program can't correctly determine its home directory (where the app and all its files are located). What can go wrong:
- SunVox: loss of the previous session, incorrect copy/paste;
- Virtual ANS and other Pixilang-based apps: program can't start at all, and you will just see the Pixilang file selection window.
open Terminal and enter the following command: xattr -r -d com.apple.quarantine /PATH_TO_THE_APP/APP.app
xattr -r -d com.apple.quarantine ~/Desktop/virtual_ans/START_MACOS.app
xattr -r -d com.apple.quarantine ~/Desktop/sunvox/sunvox/macos/SunVox.app
2) move the APP to some other folder (using the Finder only!), then move it back;
try to launch the APP;
if it still doesn’t open:
right click on the app and press Open;
or go to the system settings -> Security & Privacy -> confirm the opening of the APP (usually at the bottom of the window).
where APP is one of the following files: SunVox.app or START_MACOS.app.
