Advertisements I occasionally use KMTTG to transfer stuff from my Tivo to my Macbook pro- which means my expertise level is pretty low. I get it to work, but don't know it in depth. I have a Tivo bolt running TE3. I tried to launch it today and it said I need to download Java Developer Kit. So I found that (I believe possibly at Oracle). Did the download jdk-13.0.2_osx-x64_bin.dmg. Then tried to launch again, but this is what I am now getting a pop up box saying this... The Java JAR file "kmttg.jar" could not be launched. Check the Console for possible error messages. Any insight or suggestions?
