WEKA FOR MAC FOR MAC OS
Click here to download a disk image for Mac OS that contains a Mac application including Azul's 64-bit OpenJDK Java VM 11 JVM (weka-3-9-4-azul-zulu-osx.dmg 143 MB) #Old versions All old versions of Weka are available from the Sourceforge. Launching via the Program Menu or shortcuts will automatically use the included JVM to run Weka. On December 13, we replaced weka-3-8-3-oracle-jvm.dmg and weka-3-9-3-oracle-jvm.dmg on SourceForge with a new.dmg compatible with older versions of OS X, based on the HFS+ file system. We have identified the issue with the WEKA 3.8.3 and WEKA 3.9.3 applications for the Mac that, for many users, caused them to fail to start up via double-clicking.
