This morning, I attempted to run parallels compressor to reduce the size of my .hdd file. After manually running the compressor tool, it said it could not run due to the presence to snapshots. So, I opened the snapshot manager and selected the single snapshot I have and clicked delete. I sat here and watched it for over 30 minutes before using activity monitor to kill parallels. My VM was running at the time. After restarting parallels, but before restarting the VM, I again went into snapshot manager and tried to delete the snapshot. Once again, I'm sitting here for ~15 minutes. How long should this process take???? Is there a manual way to remove snapshots besides using the snapshot manager?
