Frequently Asked Questions

macZoomConductor supports Safari (via native App Extension), Google Chrome (Manifest V3), and Mozilla Firefox. Brave, Microsoft Edge, Arc, and other Chromium-based browsers are also fully compatible via the Chrome extension.

macZoomConductor tracks window positions across displays using native macOS Accessibility (AX) and Quartz APIs. When a browser window moves from your built-in Retina screen to an external 4K monitor, macZoomConductor applies your configured monitor baseline zoom (e.g. 125%) while respecting individual tab overrides and site exceptions.

Yes! Window names are persisted in local atomic settings storage and matched against session metadata. When you restore windows through macZoomConductor or reopen your session, custom names re-attach automatically.

Unlike Electron apps or scripts that constantly poll the system every 500ms, macZoomConductor uses a 100% event-driven architecture with native stdio messaging and UNIX domain sockets. When nothing is changing on screen, zero CPU cycles are consumed, keeping your MacBook cool and preserving battery life.

Each license (Annual, Monthly, or Lifetime) permits installation on up to 3 personal Mac computers for a single user.
