Apple has this weekend launched the second version of OS X after Mountain Lion aimed at developers, taking another step to fulfill the agenda promised a final release this summer and breaking with the classical tradition of renewing the version of OS X every two years. No big news with this update, but Apple advises all developers who download it while reports some details.
Perhaps the most important thing is that OS X will inform you with an alert every time an application tries to access the information of your contacts . In addition, we have a new section in System Preferences where you can see which applications enjoy our permission to roam on our agenda, facilitating the action of removing rights of any of these applications for whatever reason. Another development that will appeal to Safari users: support for browser tabs synchronized by icloud with mobile devices. That is, we can send your open tabs in Safari on OS X to icloud and recover in our iPhone, iPad or another Mac via the cloud.
Remember: this version is still oriented to developers, and is too unstable for use as an everyday operating system . You can download it from the developer section of the Apple website, provided we are discharged from the program one hundred per year.
