Step 1

Go to System Settings > Accessibility > Zoom and toggle on "Use keyboard shortcuts to zoom" — this activates Command + Option + = / - as the baseline zoom controls across the whole screen.

Step 2

In the same panel, switch the zoom style to Picture-in-Picture if a floating magnifier lens is more useful than blowing up the entire screen — handy for referencing small details without losing context.

Step 3

Open Swish and use its two-finger gesture system to trigger zoom actions from the trackpad — faster and more natural than reaching for a three-key combination mid-workflow.

Step 4

Open BetterTouchTool, select your preferred input device — trackpad, Magic Mouse, or keyboard — add a trigger, and map it directly to the Accessibility Zoom toggle or magnification level of your choice.

Step 5

Turn on Vivid to double the display brightness when working with zoomed-in content — especially useful on MacBook screens in bright environments where magnified details can look washed out.
