- Global Hotkey:
⌘⇧2to start capture from anywhere - Region Selection: Click and drag to select — screenshot is captured when you release the mouse button
- Annotations: Draw rectangles (
R), arrows (A), text (T), with customizable colors — or select/move them (S) - Auto-save & clipboard: Copies to clipboard and saves to a configurable location (default
~/Pictures/ScreenGrab/) - Preview thumbnail: macOS-style thumbnail after capture — click to reveal in Finder
brew install domsleee/tap/screengrabNote
ScreenGrab is ad-hoc signed and not notarized with Apple (same approach as AeroSpace). The Homebrew cask automatically strips the quarantine attribute during install so macOS Gatekeeper won't block it. If you download the zip manually from GitHub Releases, you'll need to run xattr -d com.apple.quarantine /Applications/ScreenGrab.app before launching.
xcode-select --install # if needed
git clone https://github.com/domsleee/ScreenGrab.git
cd ScreenGrab
bash scripts/install.sh # builds and copies ScreenGrab.app to /ApplicationsLaunch ScreenGrab — it runs in the background with a menu bar icon. Click the icon to start a capture, open settings, or quit.
macOS will prompt for Screen Recording permission on first launch (System Settings → Privacy & Security → Screen & System Audio Recording).
