Screen Magnifier for macOS
About ScreenZoomer
ScreenZoomer is a native macOS screen magnifier for people with low vision and anyone who needs to enlarge screen content in real time. It magnifies up to 20×, can optionally follow the mouse pointer or the keyboard focus, and can invert colors for better contrast. It is operated through a compact floating panel and configurable keyboard shortcuts.
Available on the Mac App Store: apps.apple.com/app/id6761250606

FAQ
1. Permissions
Q: What permissions does ScreenZoomer need?
A: ScreenZoomer only requests a permission when a feature actually needs it.
Screen Recording is required when magnification is enabled. This lets ScreenZoomer capture the screen content that should be magnified.
Accessibility is only required for Follow Keyboard Focus and Vector Text Sharpness. Follow Keyboard Focus uses the position of the active text caret so the magnified view stays near the typing position. Vector Text Sharpness can read visible text and render it more sharply within the magnified area.
2. How to zoom
Q: How do I start zooming?
A: Open the control panel and turn on the Magnification toggle. Alternatively, you can use the configured keyboard shortcut. Adjust the zoom factor with the slider (1× to 20×) or the +/− buttons. Keyboard shortcuts can be customized in the app.
3. Keyboard shortcut not working
Q: My keyboard shortcut doesn’t work anymore.
A: First check the keyboard shortcut settings in ScreenZoomer. Some combinations are reserved by macOS or other apps. In that case, choose a different combination and restart ScreenZoomer if the change does not take effect immediately.
4. Free trial and subscription
Q: How does the free trial work?
A: ScreenZoomer starts a 7-day free trial automatically the first time you launch it. No credit card or sign-in is required to start. During the trial, the features of the Mac App Store version are available. Before the trial ends, pick a monthly or yearly subscription inside the app (click Subscription… in the menu-bar icon or tap the trial banner at the top of the control panel). You can cancel any time in System Settings → your Apple-ID → Subscriptions.
5. Restore a purchase
Q: I bought a subscription but my new Mac doesn’t see it.
A: Open the subscription panel inside ScreenZoomer (Subscription… in the menu-bar icon) and tap Restore Purchases. Make sure the new Mac is signed in with the same Apple-ID that originally bought the subscription. Subscriptions are tied to the Apple-ID, not to the device.
6. Zoom feels slow or laggy
Q: The magnified image feels slow or laggy.
A: First make sure Screen Recording is allowed for ScreenZoomer. Without this permission, magnification cannot work correctly. With external displays, ScreenZoomer magnifies the screen where the mouse pointer is. If many apps are running at once, closing some can free up GPU and memory resources.
7. Contact support
Q: How do I contact support?
