This guide shows you how to configure macOS Tahoe for maximum performance using only built-in system settings. No third-party tools required—just macOS features that make your Mac faster and more responsive.

1. Reduce Visual Effects

Less animation and transparency means your Mac uses fewer resources for graphics.

  1. Click the Apple menu → System Settings.
  2. Go to Accessibility → Display.
  3. Turn on Reduce transparency to simplify window borders and menus.
  4. Turn on Reduce motion to limit system animations and scrolling effects.

Your Mac will look simpler but respond faster, especially on older hardware.

2. Configure Energy Saver

Battery settings can limit performance. Plug in your Mac and adjust settings for maximum power.

  1. Click the Apple menu → System Settings.
  2. Go to Battery or Energy Saver.
  3. If using a laptop, click Battery tab and adjust settings; then click Power Adapter tab.
  4. Turn off Low Power Mode when plugged in.
  5. Optionally disable Automatically adjust brightness if you prefer consistent display performance.

When plugged in, macOS can run the CPU and GPU at full speed without power-saving throttling.

3. Storage Optimization

macOS has built-in storage management that keeps your system running smoothly.

  1. Click the Apple menu → System Settings.
  2. Go to General → Storage.
  3. Turn on Optimize Storage to automatically delete seen movies, empty Trash after 30 days, and clear mail attachments.

4. Adjust Display Settings

Scaling and resolution affect how much processing your Mac needs for graphics.

  1. Click the Apple menu → System Settings.
  2. Go to Displays.
  3. Click Resolution and choose More Space option for better performance.
  4. If using multiple monitors, consider extending rather than mirroring to reduce GPU load.

5. Increase Keyboard and Mouse Speed

Faster input response makes your Mac feel more responsive.

  1. Click the Apple menu → System Settings.
  2. Go to Keyboard → Keyboard Speed.
  3. Drag the Key repeat slider all the way to the right for fastest repeat rate.
  4. Go to Accessibility → Pointer Control → Trackpad Speed (or Mouse Speed).
  5. Drag the Tracking speed slider to increase cursor movement speed.

6. Safari Performance

The default browser has built-in settings that improve performance.

  1. Open Safari.
  2. Go to Settings → Privacy.
  3. Turn on Prevent cross-site tracking and Block all cookies.
  4. Go to Advanced and enable Show Develop menu in menu bar.
  5. From the Develop menu, select Empty Caches regularly.
