macOS Tahoe, Windows 11, which operating systems for 4D 20 and 21?

As Apple and Microsoft continue to evolve their platforms, we make sure 4D stays perfectly aligned.

With each new OS release, our teams rigorously test and certify 4D to ensure you can upgrade your environment with confidence, whether you’re running macOS or Windows.

Our latest compatibility matrix below summarizes the situation as of November 2025 for both shipped and upcoming 4D versions.

🖥️ On the macOS side

After Sonoma and Sequoia, macOS 26 Tahoe is now available.

The first 4D releases to be certified with macOS 26 Tahoe are 4D 20.8 LTS and the upcoming 4D 21 LTS. If you’re using 4D 20 R10 however, it is compatible with macOS 26 Tahoe.

🪟 On the Windows side

Windows 10 support has ended on October 14, 2025. Thus we won’t certify new 4D releases on Windows 10 from now on.
