Hi elessar13,
My guess since its stopping at the drive selection is that its encountering a problem when trying to list the available drives on your system. Unfortunately it looks like the application freezes before it can write an error to the minion0.log.
If you have Java8 installed on your mac we could try and run Minion from command line and see if we get any better errors?
Open up your terminal window and type the following:
If it says you are running 1.8.xxxx you should be good. Now type the following in the terminal:
Code:
java -jar /Applications/Minion.app/Contents/Java/Minion-jfx.jar
Please copy and paste your terminal log here when it freezes.
