VMware Fusion: Not Enough Physical Memory

KB ID 0001715 Problem I upgraded to macOS Big Sur this week, and was surprised everything still worked!

VMware: Cannot Resize a VMs Hard Drive?

KB ID 0001704 Problem One of the lads in support messaged me this week, he needed to raise the size of the hard drive on a VM, and the option was greyed out (not available).  Solution Now assuming you actually have the rights to do this, the problem is ‘nearly always’ that the ‘disk’ in question has an active snapshot on it.
