OS X GRAPHICAL CLIENT SOFTWARE
Folding in the aqua interface! New! Version 4.00!: See the Release Notes if you're upgrading

Installation Instructions: 1) Go to the download page and click on the Download link for the Mac OS graphical client (you may have to do a "Save link as" if just clicking brings up a browser screen showing garbage).
2) This will put a file called "FAH4-GUI.dmg" on your Desktop. If it doesn't mount automatically, double click on the file to mount the disk image FAH4-GUI and open that. Copy Folding@home to your Desktop. You may now trash the disk image.
3) Double click on the Folding@home icon to start the application. The first time you run it, the Preferences window will pop open. You can fill in your Identity (so that you can track your work on the statistics web page). The application will automatically download the scientific core (takes a few minutes). Then, it will get to work. You can view the protein by choosing Display Protein from the Folding@home menu.
Auto Start: If you want, you can have Folding@home start up automatically each time you start Mac OS X.
For OS 10.0 - 10.2 users: Just open the System Preferences, click Login (it's listed in the first row), click the Login Items tab that appears, click the Add button, select Folding@home, and click Open. Now, Folding@home will start up every time you login without you having to do anything.
For OS 10.3 users: Just open the System Preferences, click Accounts (it's listed in the System row), click the Startup Items tab that appears , click the [+], select the Folding@home application "fah4" from the file dialog, and click Add.
