Ben jij lid van Apple’s OS X ontwikkelaar-platform en doe je mee met de betatest van OS X 10.8 Mountain Lion? Dan staat er een download voor je klaar! Apple heeft een derde preview uitgebracht van de Mountain Lion Developer Preview. Hierin zijn vooralsnog geen nieuwe functies gevonden. Er zijn dus vooral bugs aangepakt. In de release notes is desalniettemin nog een waslijst aan onopgeloste bugs te vinden.

Apple kondigde OS X Mountain Lion twee maanden terug aan. De opvolger van 10.7 Lion brengt OS X en iOS dichter bij elkaar door toevoeging van elementen als Game Center en Notification Center. Deze zomer komt Mountain Lion op de markt. Een definitieve lanceerdatum zal waarschijnlijk bekend gemaakt worden tijdens de WorldWide Developer Conference die volgens bronnen in juni gehouden zal worden.
