It looks as if VMWare has made some great headway into getting the 2013 model MacPro to work with ESXi 6.5. The install process went straight forward just as noted in VMWare KB: 2149537 – Installing ESXi 6.5 on Apple MacPro 6.1 fails, that was post three days ago. Here are the additional steps, past a basic installation, as aforementioned, that got the installation going. See the original article posted by VMWare’s William Lam over at VirtuallyGhetto.
Select the install media
Press “Shift+O” as soon as the first screens pops up.
Add the boot parameter “prefervmklinux=True”, hit enter and continue through the installation as normal and then restart.

Once the host has restarted, login and enable shell.
Enter the shell there at the DCUI by pressing ALT+F1.

esxcli system settings kernel set -s preferVmklinux -v FALSE
esxcli system module set – -enabled=false –m vmw_ahci
