I'm a past Parallels user (and VMware and VirtualBox) evaluating Parallels 14 for possible migration from VirtualBox. It seems fine for my needs (and a lot faster), except that I can't mount any virtual disks on my Mac. I don't need to mount the hdd when the guest isn't running, so didn't try that, but when I try to open my Windows 10 VM by opening the pvm file or the hdd inside it with the Mounter app, nothing happens. I don't know where to look for an error log. I tried installing the Toolbox, but that didn't have anything that helped. Right now, I'm at a loss as to how to proceed, and I don't even know how to submit a support request without Twitter or FaceBook or some other social media tool that I don't use. Thanks in advance for any suggestions.
