over the past few days I have been able to install an older driver, the most recent driver, and GearBox. But half the time when I'm trying to install I see an exclamation point over my hard drive when it asks to select a volume. Right now I have Gearbox installed but no driver and any driver I attempt to install doesn't let me because I can't select the volume. Any idea how I can get it to allow me to select the volume? I'm using a mac with Sierra.
