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.
