MacOS Support

[Desyncfy]

Can probably be fixed by removing sandbox or changing permissions in it

Notes:

• Most of the functions in the app are built to support MacOS, it's the filesystem permissions stopping us.
• Removing sandbox does not fix it.
• chmod 777 on java does not fix it.
• The specific error is a permissions error when trying to run the copy of Java it saves.
• The main issue is that having a space in the directory breaks everything. This is an upstream issue and hard to fix. This combined with the permissions crap is, to put it lightly: very annoying.
