Microsoft released the first Insider Build of Windows 11 (22000.51) earlier this week. To be receiving this build, you’d need to enroll in the Dev Channel of Windows Insider Program. That was only one of the prerequisites. Amongst the minimum system requirements is TPM 2.0. This is a questionable barrier and most likely imposed by OEMs to promote new hardware sales. It also negatively effects Intel Macs because Apple firmware does not support TPM.

Fortunately, there are ways to trick the Windows 11 installer in to bypassing these system requirements. I tried it on several machines including 2018 Mac mini and 2019 13-in MacBook Pro. Below are the steps I took to successfully getting my Macs upgraded to Windows 11 Insider Preview 10.0.22000.51.
- Complete a Windows 10 install through Boot Camp Assistant and install Boot Camp drivers.
- Enroll in Windows Insider Program and select the Dev Channel then install available updates.
- Create a REG file in Notepad with the output below, double-click to add to values to the registry then restart.
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig] "BypassTPMCheck"=dword:00000001 "BypassSecureBootCheck"=dword:00000001
- Open Windows Updates to check for Windows 11 Insider Preview 10.0.22000.51 and proceed with download.
- When the download stops at 8% with a message that it has encountered TPM 2.0 error 0x8024a205, download the modified appraiserres.dll to replace the one in C:\$WINDOWS.~BT\Sources folder.
- Restart the system and click the [Retry/Fix Issues] button in Windows Updates.
- Windows 11 installer should proceed when the Almost Ready message appears.
rename appraiserres to appraiserRes.dll and it will work.
for those who don’t know how to make a reg file in notepad look it up mostly copy and paste.
I don’t think you’re able to do this if you’ve updated to the latest Windows release. This is the only thing I see inside “Release Preview Channel”

@Jack, We can do a manual REG change to switch to Dev Channel. Open Notepad then save the output below to a .reg file. I did this just now on a 2019 16-in MacBook Pro.
Thanks @itsage, For some reason the .reg file did not work so I opened regedit with admin and changed manually. Anyways, currently downloading Windows 11 Preview through Windows update!
@itsage, Thank you! Do you possibly have some benchmarks from Mac Mini? Superposition maybe
@Susurs, Take a look at my most recent build using the 2018 Mac mini + RX Vega 56 Gaming Box.
Thank’s a lot! : )
Replacing appraiserres.dll doesn’t works for me: everytime when the “Windows 11 Update” window appears it atuomatically replace the file back to the original one, and the TPM 2.0 warning shows again.🙁
IM in the same boat! 🙁
I’m getting the same issue as another commenter. Every time I try to update, it fails and reverts the appraiserres.dll file to its original version. Is it possible to prevent this? I know I am trying to update to a later version of windows 11. Did windows patch this out? I also tried a separate guide not specifically for bootcamp, involving creating a new entry in the registry. https://windowsreport.com/install-windows-11-without-tpm/ If you want to read it. I’m going to try the ISO modification method next but we will see.
Why out of a sudden an AMD Vega eGPU works without error 12 in Windows 11?
@macrix, The host machine is most likely the determining factor. The eGPU and Windows have some impact but not always the main culprit when it comes to error 12.
Curious to see if you had any luck with Windows 11 on a MacBook Pro 13″ 2020 w/ eGPU or is that a no go all the way?
This to determine to see if this setup that I have is somewhat future proof.
@Step, I have not tried Windows 11 with my 2020 13-in Ice Lake MBP. It’s unlikely to work with AMD eGPU. After trying W11 on my 2019 16-in MBP without success, I’m going to wait for progress on that one before proceeding.
I’ll wait it out, once everything is available and out of beta I might give it a try.
Hello,
If I use the modified Windows 11 .iso that bypasses the TPM check, could I use that to update my existing Windows 10 Boot Camp installation on my Macbook Pro or do I need to create a fresh install (as in deleting the existing boot camp install and re-install windows 11 through bootcamp.)
@JazzKnight, Try upgrading from within Windows 10 and see if the installer would let you proceed.
After Installation of Windows 11, it is never advisable to use the Boot Camp’s single installer. Rather, I used individual drivers that were missing selectively. However, it is very unfortunate that Drivers for Apple Internal Keyboard / TrackPad does not work even after the installation. Just the basic operation that were working while installing Windows 11 keeps working. FaceTime HD Camera (Built-in) works but the Device Manager shows ‘drivers missings’. That includes, Apple IR Reciever too, missing drivers. Boot Camp seems to be still behind with Microsoft Visual C++2012 resulting Blue Screen of Death (BSOD) with Code: WDF Violation.

@Ngyamtso Temphel, It sounds like you did a clean Windows 11 ISO install through Boot Camp Assistant rather than Win10 ISO then Win11 upgrade in Boot Camp. My 2019 13-in MacBook Pro and 2019 16-in MacBook Pro are working well going through the two-step Win10 ISO to Win11 upgrade.
Hey there! Last night I installed Windows 11 Pro my favourite way, as a To-Go-Version on an external drive. It’s not only because I am using a, by size, fairly limited 256 GB Apple SSD, but also because I like to disconnect my gaming stuff when I want to concentrate for work. It’s running and my setup does work as it did on Windows 10 Pro before. I even have the slight impression that the graphics driver’s installation wasn’t such a big effort (no need to use Display Driver Uninstaller in Safe Mode e.g.) For the installation I used… Read more »
