Mac OS X MELTS

small logo

Mac OS X version 10.3.6+ or 10.4.5+ required for PPC-based systems
Mac OS X version 10.4.11+ or 10.5.7+ required for Intel-based systems

This page provides instructions for configuring your Mac OS X system to run a native version of the MELTS/pMELTS software package. The most up to date version of MELTS/pMELTS is available for Mac OS X version 10.5.8 (Leopard, intel) or 10.6.1 (Snow Leopard).

For Lion (OS 10.7.x) or Mountain Lion (OS 10.8.x), download a rhyolite-MELTS executable from this link.

These executables are statically linked against the OpenMotif libraries provided by the FINK group. They should run under any Mac OS X server implementation and have been tested with the Apple X11 server.

The Mac OS X version of MELTS/pMELTS is the most up to date release of the code available. Many numerical algorithms have been enhanced and several interface problems have been corrected. The "Compute Redox State" bus error has been fixed. Scroll bars have been added to the popup assimilant dialog box so that users with average sized monitors can access the text boxes at the bottom of the dialog. And, a number of problems associated with reading input files that contain assimilants have been corrected; negative concentrations of solid components in assimilant phases can now be entered from the interface.

Download and Configuration of MELTS/pMELTS

  • Verify that the Apple X11 server application is installed in the Utilities sub folder of the Applications folder. It should have been installed with OS X 10.3, 10.4, 10.5, 10.6 or along with a 10.2.x to 10.3 upgrade. If it is not, go to the Apple web site and download the application.
  • Optionally, go to the FINK web site, and follow the instructions to download and install the Grace graphics package. Grace is utilized by MELTS/pMELTS to display graphical output. Without Grace, the graphics window will not display when invoked from the MELTS/pMELTS user interface. The FINK installation procedure involves a number of steps, and if this procedure seems like too much trouble and you would rather not deal with FINK, just ignore the Grace installation for now as MELTS/pMELTS will function without it (sans graphics).
  • For 10.3.6 or later versions of Mac OS X running on PPC-based systems-> Download the compressed executable image of MELTS/pMELTS from this link and save the file as Melts-public.gz to the hard drive.
  • For 10.4.5 or later versions of Mac OS X running on PPC-based systems-> Download the compressed executable image of MELTS/pMELTS from this link and save the file as Melts-public.gz to the hard drive.
  • For 10.4.11 or later versions of Mac OS X running on EITHER Intel- or PPC-based systems-> Download the compressed executable image of MELTS/pMELTS from this link and save the file as Melts-public.gz to the hard drive. This version will not run on Snow Leopard (10.6.x).
  • For a 10.5.7 version of Mac OS X running on an Intel-based system-> Download the compressed executable image of MELTS/pMELTS from this link and save the file as Melts-public.gz to the hard drive. This version will have interface problems on Snow Leopard (10.6.x).
  • For a 10.5.8 or later Leopard version of Mac OS X running on Intel-based systems-> Download the compressed executable image of MELTS/pMELTS from this link and save the file as Melts-public.gz to the hard drive. This version will have interface problems on Snow Leopard (10.6.x).
  • For a Snow Leopard (10.6.1) compatible version of Mac OS X-> Download the compressed executable image of MELTS/pMELTS from this link and save the file as Melts-public.gz to the hard drive.
  • Open the OS X Terminal utilities application and navigate the directory tree to the location where the file Melts-public.gz is located.
  • If your browser automatically decompresses gzipped files (e.g. Safari) this step may not be required. But, if it does not, in the terminal window run the Unix command gzip -d Melts-public.gz to decompress the executable image.
  • In the terminal window run the Unix command chmod 755 Melts-public to ensure that the executable image has the correct permissions.
  • Optionally move the executable image to a convenient directory.
  • Optionally, download the MELTS input file morb.melts and the pMELTS input file mm3.melts for testing purposes.
  • Start the X server: double-click the X11 icon.
  • In a terminal window created by the X server, navigate to the directory where you have placed the MELTS/pMELTS executable and start the program by typing ./Melts-public. You will be asked to choose MELTS or pMELTS mode and the interface should display on your monitor. Resize as appropriate in order to see the entire interface.
