Since Make Demos is downloaded directly, macOS may require a quick permission step. Run this command in Terminal after installation:
xattr -rd com.apple.quarantine /Applications/MakeDemos.appThen go to System Preferences → Security & Privacy to grant "screen recording" and "accessibility" permissions.
Download the .AppImage file, make it executable, and run:
chmod +x MakeDemos-Linux-*.AppImage./MakeDemos-Linux-*.AppImageYou may need to grant screen recording permissions depending on your desktop environment.
