I have a mac (I know many people don’t think its the best for gaming) and I want to download the Biomes O’ Plenty mod. I have forge for 1.8 and 1.6.4 so it would have to be compatible for one of the 2 versions. I have tried to download the version for 1.6.4 (as I can’t find it for 1.8) onto my mac but whenever I click on the download it says “The Java JAR file “BiomesOPlenty-universal-1.6.4-220.127.116.114.jar” could not be launched. Check the Console for possible error messages.” Am I doing something wrong? Please help as this is my first mod download so I have no idea what I’m doing. Thanks.
