Mesquite installation for MacOS X

System requirements: Mac OS X 10.6 or higher, with Java 1.6 or higher.

  1. If you have an older version of Mesquite, you may want to delete it (by deleting Mesquite_Folder), so as to avoid getting confused as to what version of Mesquite is starting up. First, however, you may want to take from Mesquite_Folder/mesquite any third party packages (e.g., PDAP, TreeSetViz) before deleting the directory.
  2. Download the latest version of Mesquite from the Mesquite Github repository. For Mac OS X, use the files ending in .dmg. There are two alternatives, one for Java 1.6 (recommended for OS X 10.9, Mavericks, and lower), the other for Java 1.7 and above (recommended for OS X 10.10, Yosemite, and higher).
  3. If the downloaded file doesn't mount into a disk image automatically, double click it to mount. You will see a Mesquite_Folder. Drag this Mesquite_Folder to your hard drive (e.g., your Applications folder). Its contents should be approximately as follows:
    • Mesquite_Folder
      • com/
      • corejava
      • documentation.html
      • edu/
      • examples/
      • images/
      • jars/
      • lesser.txt
      • lib/
      • mesquite/
      • org/
      • OtherWaysToStartMesquite
      • settings/
      • README-Starting Mesquite on Mac OS X.txt
  4. Double click the Mesquite icon to start Mesquite. If you don't have Java installed, you will be asked to install it.
  5. There are other executables to start Mesquite, within the folder OtherWaysToStartMesquite. They give you different options, for example, for amount of memory used. See the file "README-Starting Mesquite on Mac OS X.txt" for instructions.
  6. On Mac OS X 10.9 or below, Mesquite runs best with Java 1.6. On Mac OS X 10.0 or higher, Mesquite runs best on Java 1.7 or higher. To install Java 1.7 or higher, get it from
