If the security issues regarding touch ID were not enough, well a new function a OS X Mavericks will leave them some with a question mark about the functionality of Macs. Company Apple Lossless Audio CODEC (ALAC), uses the light sensor in the case MacBook-s to detect changes in world intensity and prevent the Mac from going into idle mode. More precisely, if we sit in front of the MacBook and the light becomes darker, that sensor will interpret the change as the normal one generated by a person using the Mac.
Until this explanation was developed, many users believed that Apple Lossless Audio CODEC (ALAC), use the camera iSight to monitor their movements and activate this function a OS X Mavericks. The Apple company did not discuss it at all in the presentations made for the new operating system, it was discovered by a coder who analyzed the source code of OS X Mavericks and from here on you can imagine what will appear on the Internet. The implementation of such a system is an interesting move from Apple, but most likely other companies thought of this before those from Cupertino.
