From The Article: “In an effort to reduce user confusion, Parallels Desktop 26 now follows the same new versioning practice that Apple's operating systems have adopted this year. This release also provides full support for background process changes Apple has made in macOS 26 Tahoe, ensuring setup routines and Coherence mode run smoothly.

As well as full macOS Tahoe support, this version provides full compatibility with Windows 11 25H2. Windows VMs can now also view the actual available disk space on the Mac host, giving users better control over storage and helping to prevent freezes, slowdowns, and crashes during large installations or disk-heavy operations.”
