    That's interesting, @mcored, It has to be one of two things. I checked the KB articles again and they don't specify it only works on certain Macs. It does say Parallels must be either
    • Parallels Desktop for Mac Pro Edition
    • Parallels Desktop for Mac Business Edition
    Are you running either of these versions of Parallels?

    Or - if you go to Hardware > +, but a TPM chip isn't there, it means your Windows virtual machine is based on Legacy BIOS. TPM chip will work with UEFI/EFI BIOS only.
    1. If Legacy is set, create a new Windows virtual machine.
    2. When you get to the Name and Location window when creating a machine, enable Customize settings before installation.
    3. In the automatically opened configuration window go to Hardware, click + > select TPM chip > Add.
    4. Close the configuration window and proceed with Windows installation.

    I have UEFI bios mode, but still no TPM chip option

    Thanks for your response.
    I have the latest Pro version. Using Boot Camp, I installed Windows 10 freshly in August 2020 using my brand new iMac 27" (2020).
    When I go to State Information, it does say I have UEFI.
    This is why I'm out of options again.

    I've reach the stage of UEFI - TPM - But alas the cpu on my MBP is not on the list for Windows 11 7657U i7 5.5GHz (2017)

    That should have read 3.5GHz CPU

    To fix This PC Can't Run Windows 11" message you need to turn on TPM as well as the Secure Boot option on your system.
    But first, also confirm if your system meets the minimum system requirements. And if everything seems fine then the motherboard has a TPM 2.0 chip. This component is mostly present on many PC, but you are using an old PC then it might not present. Follow the steps to enable TPM 2.0 to run Windows 11.
    • Reboot and press F1, F2, F10, or F11 to open the Startup Menu
    • Now, click on 'Security Tab'
    • Click on 'TPM device' and a list will available
    • Now select 'Available'
    • Click on save and reboot your PC.
    Hope This PC can't run Windows 11 is resolved but if not then this can be shown mistakenly by Microsoft and get resolved with time.

    I've been able to get W11 up and running on a VM DT v16.5 (MBP 13" 2017) ..
    But it was only a very early version of W11

    I just upgraded my standard edition of Parallels to the Pro edition to have the option of adding a virtual TPM Module. This works fine, but how did you manage to not get a warning concerning the processor type and having a DirectX 12 compatible graphics card?

    This is what I was thinking too. We got no hope for Boot Camp installations i.e. native installations, however, we might have luck installing Windows 11 virtually through Parallels Desktop in the future.

    Alright, I deleted the Boot Camp partition and reinstalled Windows through Parallels Desktop. This time I am able to add the TPM module. I guess the problem child was Boot Camp installation.

    On ARM Macs you can run Windows 11 just fine. You dont need a TPM chip as of yet. I have Windows 11 via the Insider Preview as a Windows Update (dev channel).

    I wonder if in the future Parallels will add the ability to switch to UEFI from BIOS via the settings without redoing a VM, as that would make it much easier to enable TPM 2.0 option.

    Also the minimum RAM and minimum storage needed have increased for Windows 11

    TPM emulation is only in the Business and Pro versions of Parallels, not Standard. This will be a problem when Windows 11 finally requires TPM. I'm very curious as to whether Parallels (the company) is planning to extend that feature down to the Standard version, or if those of us with Standard just aren't going to get to have Windows 11, ever.

    By shear luck I seem to have found a way to switch from BIOS to UEFI via the Parallels GUI:
    1. Having run "mbr2gpt /convert" via the Windows Troubleshooting Terminal menu, close the amended VM
    2. With the VM turned off, open the VM Config GUI and select hardware / boot order / advanced
    3. Under Advanced / Boot Flags add "vm.bios.efi=1" and select OK
    4. My "converted" VM now boots and with "msinfo32" I can see BIOS Mode is UEFI
    5. Opening the VM Package Contents on my Mac Pro 5,1, I can edit config.pvr and see that EFI=1 too.
    Unfortunately I'm still stuck as the option to add a Virtual TPM under the hardware config setting is missing. The msinfo32 tool provides the reason under the "Device Encryption Support" entry: "Reasons for failed automatic device encryption: TPM is not usable, PCR7 binding is not supported..."
    PS: according to the Parallels website Parallels V17.1.0 Standard Edition supports "Use a Virtual TPM chip".
    Anyone got any ideas where we go from here?

    JohnS102, you shouldn't add flag "vm.bios.efi=1"
    It's better to edit config.pvs file and set <EfiEnabled>0</EfiEnabled> field, to <EfiEnabled>1</EfiEnabled>
    Another way (I'm not sure it is available for Parallels Standard Edition) is to run in terminal two commands:
    prlctl set <VM_UUID> --bios-type efi64
    prlctl set <VM_UUID> --efi-secure-boot on
    <VM_UUID> can be found, from 'prlctl list -a' output for example.

    Hello, please update to Parallels Desktop for Mac 17.1.0 for resolving the issue. Thanks, Parallels Team.

    Hi, thanks for the suggestion - are you suggesting that adding a BIOS to UEFI flag via the Config GUI might explain the PCR7 bindings problem? The comment from Parallels Staff Member doesn't help as I AM USING Parallels 17.0.1 and I've still got the PCR7 bindings problem!!

    JonhS102, from my POW this thread is not about "PCR7 bindings problem" if it exists.
    Do you get TPM working/accessible for Windows? Does 'tpm.msc' applet see it?

    And I replied in context of
    To add Virtual TPM via GUI in config editor <EfiEnabled>1</EfiEnabled> must be set.
