			<ul>
			<li>sudo xattr -rd com.apple.quarantine /Applications/AutoFOCUS3.app</li>
			<li>As our software is a scientific prototype, our product is not signed which causes a problem due to the security restrictions of MacOS</li>
			</ul>
		</li>
		</ul>
	</li>
	<li> On Windows: DSE does not execute and throws exception
		<ul>
