Apple macOS 10.15 guest operating system option not available during VM creation

Products

• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

Symptoms:
No selection for macOS 10.15 is available in vSphere during the process of creating or editing a virtual machine. This affects VMs with a virtual hardware version below 17.

Environment

VMware vSphere ESXi 6.7
VMware vCenter Server 6.7.x

Resolution

• To resolve this issue on vSphere 6.7 Update 3, which supports virtual hardware version up to 15, select Apple macOS 10.14 (64-bit) as the Guest OS instead. 
• To resolve this issue in versions of vSphere later than 6.7 Update 3, use virtual hardware version 17 or greater.

Note:

• The VMware Compatibility Guide - Guest OS is the authority on supported configurations of third-party hardware and software, including Guest Operating Systems, certified with vSphere/ESXi releases. In the VMware Compatibility Guide, you will find that support for macOS 10.15 was introduced with vSphere/ESXi 6.7 Update 3.
• The best practice VM configuration is to use the Guest OS selection that best matches the operating system running in the VM. However, an exact match may not be available for a specific operating system. Typically this is a result of cases where a new operating system was released after a particular vSphere release already became generally available. In such cases, the result of successful certification testing for new operating system releases is published in the VMware Compatibility Guide along with links to KB articles containing information with any related special guidance, including the use of an alternate guest operating system selections where an exact match is not available.
