Java 1.5 comes preinstalled on Mac OS X 10.4 or later, so you won't need to install it yourself.
Python, which the Skeinforge toolpath generator uses to do its magic, is preinstalled on Mac OS X. However, if Python is giving you trouble, you can download and install version 2.7.2 from Python.org.
Copy to Applications
- Mount the .dmg file.
- Create a new subdirectory in Applications to contain ReplicatorG and all its parts. Call it replicatorg.
- Select all the contents of the mounted .dmg file and copy them into you new replicatorg folder in Applications.
Note: If you try to run ReplicatorG directly from the mounted disk image, it will complain about running from a read-only directory and exit. Likewise, if you copy only the ReplicatorG.app file from the image and not the rest of the image contents, you will not be able to run the application.
There is a /drivers folder in the replicatorg folder you installed. It contains a driver for the FTDI USB->Serial converter used with Arduino and Sanguino boards. If you have already installed Arduino, you can skip this step. Otherwise, please install it.
You can run the ReplicatorG application by double clicking the ReplicatorG icon.
