You need to be a bit more specific on where Windows is telling you that it can't do the upgrade.Did you run PC Health Check (https://support.microsoft.com/en-us/windows/how-to-check-if-your-device-meets-windows-11-system-requ...) in the VM before trying the upgrade? It'll tell you what's not meeting Windows 11 pre-requisites.
In general, the Windows 11 upgrader will fail if:
- You do not have UEFI secure boot enabled. Make sure that's enabled for the VM.
- You do not have the VM configured with a TPM device. You need to turn on VM encryption (choose only to encrypt the files needed to support TPM, not complete encryption), then make sure the TPM device is added to the VM.
- You do not have the VM configured with at least a 64GB virtual hard drive
- You do not have 2 vCPUs and 4GB of memory for the VM.
- the Intel CPU is not on Microsoft's list of compatible chips. From what I can tell, the Intel CPUs in that generation of MacBook Pro should be OK
If you've met all of these, check resources on the web about how to force Windows to install on unsupported configurations.
