Picked up a used Line X3 Live, struggled to figure out which app allows sharing / downloads of patches (not linked to on the X3 Live Mac downloads page, nor does Monkey list it), eventually found mention of Custom Tone and Line6 Edit, and managed to download and install Line6 Edit.
However, it will not run on my system and keeps throwing the following error dialog.
"To open "Line 6 Edit," you need a Java SE 6 runtime. Would you like to install one now? Not Now / Install"
However, I currently have Java 7 installed from Oracle which supersedes 6 which was managed by Apple and is no longer offered on the latest Mac OS X versions.
