Geneious

Running Geneious in 64 bit on Mac OS

  1. Make sure you have the latest version of Java by opening "Software Update" in the Apple menu.
  2. In your Applications folder go in to Utilities/Java and open "Java Preferences"
  3. In the Java Preferences drag the Java application version around so that a 64-bit version is at the top (see screenshot)
  4. Close the Java Preferences then go to your Geneious app.
  5. Control-Click on Geneious and choose "Show Package Contents"
  6. In the folder that is opened go in to the "Contents" folder and double click on "Info.plist"
  7. In the Plist Editor click the arrow next to "Root" to open it then open "Java" in the same way
  8. Double click on the value next to "VMOptions" to edit it and add " -d64" on the end (see screenshot)
  9. Save and close the Info.plist then run Geneious.

You should now be able to allocate larger amounts of memory to Geneious on the General tab in Tools -> Preferences.
