Perhaps someone can direct me to some definitive solutions.
I have not been able to get any version of Toast newer than version 11 to work on
any Mac newer than 2012.
Two cases in particular
Macbook Pro 2012 w/optical drive, and Macbook Pro Retina 15" 2014 w/ USB OWC external optical drive attached
anything newer than Toast 11 either freezes outright on start up or starts up then does not "respond" requiring a force quit
I have seen a few sites with this issue discussed, but with no workable solutions, for me anyway ...
thanks for any advice .
