Frequently asked.

macOS 13.0 (Ventura) and later, on both Apple silicon and Intel. The bundle is compiled for the build machine's architecture, so Intel Macs need the x86_64 build — running arm64 under Rosetta slows capture noticeably.

The build is self-signed rather than notarised with a paid Apple Developer certificate. Right-click the app and choose Open, or use Open Anyway in System Settings → Privacy & Security. One time only.

That usually means the signing identity changed. macOS identifies apps by their signing certificate, so a new ad-hoc signature looks like a different app. Untick MacShot, quit it, tick again and relaunch. Remove duplicate entries if present.

That's macOS's degraded response to a missing permission: wallpaper and menu bar only, at full size, with window content stripped. Grant Screen Recording access and relaunch.

Area drags a box. Full screen selects the whole display. Window grabs one window's own pixels, unobstructed. Smart highlights whatever is under the cursor — a window, or the whole screen over empty desktop — and selects on a single click.

Only Smart capture is enabled by default. Area (⇧⌘X), full screen (⇧⌘F) and window (⇧⌘W) each have a switch in Settings → Shortcuts. All four can be re-recorded.

⌘Z walks back in time and you don't know which mark it will remove. ⌫ deletes the one you clicked. Nothing is auto-selected after drawing, so the selection outline is always something you chose.

No. The whole image shares one downsample base, so repeated strokes stay aligned.

Yes. Press ⇧⌘S during annotation to render the overlay — dimming, selection, handles, strokes, toolbar — without the cursor. It saves to your capture folder without interrupting the current screenshot.

Yes. Use Import in Settings → Watermark, or drag a PNG / JPG / HEIC straight onto the card. Your original is untouched; the output is a new file.

No. Capture, annotation, watermark compositing and PNG encoding all run locally. There is no account system, and no image or usage data is sent anywhere.

~/Library/Application Support/MacShot/config.native.json. Settings → About can reveal it in Finder. Copy that file to move your watermark and annotation setup to another Mac.

Swift and AppKit directly, with no bundled browser engine and no third-party libraries. The previous Electron build was 242 MB with the same features.
