Then boot your VM, go to Disk Utility and format the disk to your preferred format. Well, I’m using ESXi 6.5…….Ĭhoose the size, click ‘ok’ and it will be created. This is documented in a tech note here, but is supposed to be fixed in ESXi 5.2 and above. And there seems to be nothing you can do to fix this. Disk Utility will report that the ‘Physical’ disk is the new size, and that the ‘Logical’ disk is the old size. You say yes and everything looks like it’s gone well- it claims the extra space, but never uses it. You then delete the free space and Disk Utility will ask you if you want to expand the Mac OS partition. Here’s the problem- you can shut down the VM, use VMWare Fusion (v10.11) to increase the virtual disk size, then boot the VM and Disk Utility will see the extra space. I knew that ESXi could do this, and I knew that Mac OS can do this, but could they do it together? Unfortunately I recently came across a situation where I needed more space for an existing VM. I typically allocate my Mac VM’s 40GB of drive space which is fine for most normal operations.
