Together with supporting libraries and applications, it forms the X11.app that Apple shipped with OS X versions 10.5 through 10.7. Resize as appropriate in order to see the entire interface.The XQuartz project is an open-source effort to develop a version of the X.Org X Window System that runs on macOS.

Choose rhyolite-MELTS version 1.0.2, 1.1.0 or 1.2.0, or pMELTS mode.

In a terminal window, navigate to the directory where you placed the executable image, and start the program by typing:.

Optionally, download the MELTS input file lts and the pMELTS input file mm3.melts for testing purposes.

Optionally, move the executable image to a convenient directory.

In the terminal window, run the following UNIX command, which ensures that the executable image has the correct permissions:.

If your browser automatically decompresses the zip file, the result is named Melts-rhyolite-public.

If your browser does not automatically decompress zipped files, decompress the executable image: In the terminal window run the UNIX command unzip rhyolite-Melts-Mac-OS-10.12+.zip or unzip rhyolite-Melts-Mac-OS-10.8+.zip.

Make sure that the decompressed file is named Melts-rhyolite-public:.

Open the OS X Terminal utilities application, and navigate to the location of the file rhyolite-Melts-Mac-OS-10.12+.zip or rhyolite-Melts-Mac-OS-10.8+.zip.

(Other MacOS versions) Download the compressed executable image, and save it as rhyolite-Melts-Mac-OS-10.8+.zip.

(Sierra) Download the compressed executable image, and save it as rhyolite-Melts-Mac-OS-10.12+.zip.

Download the compressed executable image of rhyolite-MELTS/pMELTS, and save it to the hard drive:.

Log out and log back into your computer, or restart it.

For other MacOS versions, install XQuartz 2.7.7 or 2.7.8. For Sierra, install XQuartz 2.7.9 or later.

Download XQuartz from and install the application.

If this is the first installation of MELTS, install an X11 server, which ensures that the MELTS executable will launch:.

Verify that your Macintosh runs one of the following:.

Results computed using the rhyolite-MELTS/pMELTS software package should be properly cited. In addition, a number of algorithmic modifications to rhyolite-MELTS make the program less prone to numerical failures.

Consequently, application of rhyolite-MELTS to more mafic systems (or any system that is quartz and alkali-feldspar absent) should yield results identical to those from the orginal MELTS calibration. Rhyolite-MELTS is based on the original MELTS calibration with modifications that should affect only the stability of quartz and alkali-feldspar. This page provides instructions for configuring your Mac OS X system to run a native version of the rhyolite-MELTS (which supersedes MELTS) or pMELTS software package.
