When I installed Mojave I ended up with two virtual hard disks. One which I call Culber (64GB) and one which I call Stamets (6GB). Stamets seems to just have the Mojave install app, and 72 MB free space. Culver sats ut gas a caooacut if 68 GB, with ~3 GB free, and I am getting "Your disk is almost full" messages. I went in to settings and changed Culber to 96 GB. But when I boot into Mojave it does not show the 96 GB, and I still get the Disk Full message. So... (1) How do I resize Culber and (2) Is Stamets necessary?
