Hi - I just wasted almost an entire day trying to fix the same problem. After reading many responses, articles from vmware, etc, I finally stumbled across one that mentioned that the initial resizing of the virtual disk via settings, can be done while holding the option key down. Hadnt seen that anywhere. I had tried to first go from 60 to 90, fail. Showed up the same way yours did. Then to 100, fail. Then 102, fail. Then 105, with the option key held while resizing. Sure enough, go into EaseUS after and the 3 extra GM from 102 to 105 show up as unallocated. So I expanded the 102 to 105, even though the 102 had still shown as a nearly full 60. EaseUS ran, rebooted, and then did the partitioning on reboot. Opened up the VM, sure enough, 105 all set with over 40gb free. FINALLY!
So, try one more resize, slightly larger, with the option key held, THEN do the manual partition extension.
