# Now there should be an ISO called Catalina.iso in the `out` folder | |
# Upload the resulted ISO to vSphere datastore (upload to an ESXi host) | |
# Create a new VM as Guest OS set to `Other:Apple macOS 10.14 64-bit`. Don't start a VM | |
# Then compatibility should set to `ESXi 6.7 update 2 and later` and Guest OS to `Windows 10 64-bit` | |
# Start the VM, make sure that CDROM with datastore ISO (Catalina.iso) is connected | |
# Disable the Network boot option in vSphere BIOS menu. Restart VM | |
# Installer should start. You should choose Disk Utility, and initialize the VMware Virtual SATA Hard Drive Media | |
# (since keyboard ain't work - using existing `Untitled` name) | |
# Wait util installer completes. VM will not boot. Shutdown VM, change Guest OS profile back to `Other:Apple macOS 10.14 64-bit` | |
# Once Catalina is installed, download the latest VMware tools and install it. | |
# It took two reboots for me to completion (will require to unblock security extension) | |
