I'm running an older system mac 10.13.6 It states clearly on their website that a lot of their software is compatible with 10.13+ Doesn't tell you Opus doesn't work though. But I can install Play. However after installing play (Which I had to do manually because the install center only downloaded it and didn't install) It only seems to install the plugin and not the standalone. So before i take advantage of any Back Friday deals I need to make sure everything is going to install and work properly. Can anyone help on why the standalone 'Play' app is not installing? Anyone else had any problems like this?
