- Clean before installing. (Mostly to get full logs every time.)
- Clearer error messages.
- Better checking for Xcode/xcodebuild.
- Log extra system info.
- A number of minor bug fixes.
In the manual uninstallation instructions, makes the command for
restarting coreaudiod clearer. If the old command had to fallback to
"sudo killall coreaudiod", it wasn't clear to the user that it had
actually succeeded.
- Move files to the trash instead of deleting them, just in case we
accidentally delete the wrong thing.
- Added some fallback variants of launchctl commands for old versions.
- Check the size of files before deleting them, just to be safe.
- Added license/copyright heading.
BGMXPCHelper's install script now creates a user and group for
BGMXPCHelper to run as. This reduces the risk of BGMXPCHelper being used
for privilege escalation.
The "install" action for BGMXPCHelper now checks the owner/permissions
of the installation directory. It also installs BGMXPCHelper's
launchd.plist and "bootstraps" it.
