Virtual DJ, developed by Atomix Productions, has long been the industry standard for entry-level to professional DJ software. Version 8.5 marked a significant milestone. The "Pro Infinity" moniker was a game-changer: instead of paying for major upgrades (e.g., moving from 8.5 to 9), an Infinity license granted lifetime updates. However, for many Mac users, version 8.5 itself—not the later updates—became the preferred version due to its compatibility with macOS Sierra, High Sierra, and even early versions of Mojave.
