ScreenCap 2.2.0

ScreenCap 2.2.0 improves long-recording output reliability and the opened-image editing workflow.

Improvements

• Long recordings use bounded writer backpressure, explicit overflow handling and final QuickTime
  movie validation, so incomplete video is reported instead of being silently accepted.
• Video saving keeps valid timestamps and handles AVFoundation's metadata-only boundary samples
  without rejecting an otherwise playable movie.
• Images opened from Finder start at 100% scale, centre when possible, and can be panned with a
  trackpad gesture or mouse wheel from any annotation tool.
• Opened-image panning follows macOS's Natural scrolling preference.
• Saving an opened image without confirmation prefers the source folder and adds _ScreenCap
  before the extension, with a Save Panel fallback when that folder is unavailable.
• Extending an opened image's edge expands the scrollable canvas and fills only the new area with
  the current primary colour.

Pay attention to the following before the installation

⚠️ macOS will block the first launch — this is expected

This build is not notarized by Apple (that needs a paid Apple Developer account), so
macOS says "Apple could not verify ScreenCap is free of malware" and offers only Done
and Move to Bin.

Press Done, then open System Settings → Privacy & Security, scroll to Security,
and press Open Anyway next to the ScreenCap line. Once only.

On macOS 15 and newer the old right-click → Open trick no longer works. From the terminal,
xattr -d com.apple.quarantine /Applications/ScreenCap.app does the same. Building from
source avoids the warning entirely.

Install

Download the disk image, open it, drag ScreenCap.app onto Applications.

Then allow it past Gatekeeper — see the notice above.

On the first launch, if access is missing, macOS asks for Screen Recording. It is the
permission macOS requires for anything that reads the screen, including a single still frame.
