Parallels Desktop, the virtualization software for macOS, has support for a virtual TPM 2.0 module per version 17.1, allowing it to run Windows 11 again. Microsoft introduced that requirement a month ago.
Parallels announced support for Windows 11 back in August, stating that the use of a virtual TPM chip enabled the running of the new OS. In the meantime, however, Microsoft tightened its TPM requirements for VMs, which until then were somewhat looser than the requirements for physical systems. The minimum with regard to a TPM has been equalized: one must always have version 2.0, which means that VMs no longer work after an update. Parallels version 17.1 will allow the VMs to work again.
Parallels Desktop 17.1 also supports M1 hardware, macOS Monterey as guest and host, drag & drop between host and guest, better gaming performance in both 2d and DirectX11 games, and support for BitLocker and Secure Boot. In addition, Desktop can put the guest OS into battery saver mode if the host OS’s battery charge gets too low, and has better support for USB devices and improved disk space management, especially in virtual machines.
Parallels Desktop 17 is available in three versions. A new subscription of the standard edition costs 80 euros per year, a one-time purchase costs 100 euros. An upgrade to the new edition costs 50 euros. Parallel Desktop for the Mac Pro costs $100 a year or $50 a year as an upgrade from the standard edition. The business version of Parallels Desktop 17 costs 100 euros per year.
