Java 6

Some MIT applications require Java 6. If you are having a problem with an MIT application, try downgrading to Java 6:

  • Windows: Downgrade to Java 6 Release 43
  • Mac: Downgrade to Java 6
    • Run the shell script to enable Java 6 on your Macintosh: Shell script for 10.7 and 10.8
      Note: The fix will be overwritten daily, by Apple's XProtect anti-malware software. Run the script each day in order to enable Java 6 on your Macintosh.
  • Linux: Check your distribution.
