Magnify

Magnify is a lightweight macOS video conferencing tool that turns a draggable screen region into a clean full-screen live zoom view for demos, calls, and screen shares. The problem is that Cmd+Opt+8, Cmd+Opt+=, and Cmd+Opt+- do not show the same effect in live conferencing, so I built Magnify to make that zoom effect visible to the audience.

Edit mode

Presentation mode

Install

make install
open /Applications/Magnify.app

Grant Screen Recording permission when macOS prompts for it.

Release

make release-archives

That writes dist/Magnify.app, dist/Magnify.zip, and dist/Magnify.dmg. For public distribution without Gatekeeper warnings, set SIGNING_IDENTITY and optionally NOTARY_PROFILE before running the release target.

Use

• Cmd+Opt+E: show or hide the edit pane
• Drag and resize the pane to choose the region you want to present
• Cmd+Opt+M: toggle presentation mode
• Opt+8: toggle cursor zoom mode
• Opt+=: zoom in the cursor zoom mode
• Opt+-: zoom out the cursor zoom mode
