 These are self-contained — no .NET SDK required. Extract the zip and run.
 
+**macOS note:** macOS may block the app because it isn't signed with an Apple Developer certificate. If you see a warning that the app "can't be opened," run this after extracting:
+
+```bash
+xattr -cr PerformanceStudio.app
