Just installed Parallels 15 on Catlina Mac with 1TB SSD. Then installed Mojave in virtual system as guest, with default settings (which created a virtual machine roughly 64GB). I now need to increase the guest HDD ("Running out of space" dialog in guest system), but when I shut down the guest, follow directions to increase the virtual machine size, and reboot the guest, this has not changed the virtual machine size (from it's perspective). The host does indicate that the guest size has changed... I could only find references in the forums to guest windows systems with this issues, so the windows fixes aren't applicable (I am guessing). Any suggestions? Thanks
