Downloading and installing/upgrading Unity3d on Mac OS X from the command line

If you ever need to install/upgrade Unity3d on a remote mac OS X machine and you only have shell access, here is how you can do it:


$ alias wget="curl -O -L"
$ wget http://download.unity3d.com/download_unity/unity-3.5.0.dmg
$ hdiutil mount unity-3.5.0.dmg

Checksumming Driver Descriptor Map (DDM : 0)…

Checksumming disk image (Apple_HFS : 2)…

/dev/disk3 Apple_partition_scheme
/dev/disk3s1 Apple_partition_map
/dev/disk3s2 Apple_HFS /Volumes/unity
$ sudo installer -pkg /Volumes/unity/Unity.mpkg -target /
Password:
installer: Package name is Unity
installer: Upgrading at base path /
installer: The upgrade was successful.
$ hdiutil unmount /Volumes/unity
"/Volumes/unity" unmounted successfully.


Now this can be improved without manual interaction by using the -plist argument of the hdiutil mount and installer commands.

I will see if there's a way to reuse this to add a proper installer for the Jenkins unity3d plugin. I am not really sure as one often needs to have administrator privileges to use the installer command.
