WhatsOpen
WhatsOpen is a utility for macOS that displays which applications and processes are currently running on the system. It provides visibility into active apps, background services, and system processes, helping users monitor resource usage, identify unexpected running applications, and manage their system's activity. It is typically used by power users and system administrators who want a quick overview of what is executing on their Mac.
AI Recommendation
1 suggestionWe could not find reliable public information about WhatsOpen's current development status or whether a native Apple Silicon build exists. The bundle ID suggests it is maintained by AgaSupport. If you rely on this app, we recommend contacting the developer directly to ask whether they ship a native Apple Silicon build and whether they plan to support macOS 28, which is scheduled to remove Rosetta 2 in September 2028. If the developer cannot confirm native support, you should plan to migrate to an alternative process monitor in the coming months. Native alternatives include Activity Monitor (Apple's built-in system utility), iStat Menus (a more feature-rich paid alternative), or htop via Homebrew (a command-line option). Acting sooner rather than later will give you time to evaluate alternatives before Rosetta 2 support ends.
