Alternatively, with the option enabled click the Pair button and ensure that the system is paired to only one remote-control device. Screenshot by Topher Kessler Modern Mac systems do not include an infra-red sensor, but for a while Apple included these for controlling Front Row and other applications using the included remote control.
If the system senses infra-red activity, it may wake from sleep, so if you do not use the remote control, you might benefit from disabling the infrared sensor in the Security system preferences. If you do use the remote, then it may be helpful to ensure that it is paired with the system.
By default your Mac will not be paired with a specific remote, which allows it to be controlled by any remote device.
If you pair it with your remote, then it will only respond to your specified remote and ignore other infrared activity. Disable wake on network access The wake on network access options can be disabled in the Energy Saver preferences. Screenshot by Topher Kessler Apple has made extensive use of the common Wake on LAN WOL feature in network interfaces that can start up a system remotely using a special network packet called a "magic packet.
This feature is used by Apple for a number of its sharing services, including Bonjour-enabled service like iTunes sharing, Printer and File sharing, and even for Internet-based access such as Back to My Mac. Apple uses the service with its Airport Base Station or Time Capsule devices, which act as a "Bonjour Sleep Proxy" that registers the device and allows it to be accessed when it is asleep.
What Happens When You Leave Macs Idle for a Longer Period of Time?
When you try networking with the device when it is sleeping, the proxy will issue the magic packet to wake it up and allow you to access it. Even if you do not have a sleep proxy on your network, the Mac may still be woken if a magic packet is sent to it, and it will also periodically wake briefly in an attempt to register with a sleep proxy. This behavior is historically enabled on Ethernet devices, but on newer Macs you can use the Airport connection for this option as well.
If you need to do this, you had better make sure your Mac is running in your home network and nobody could use your Mac without permission except you.https://guecompnkilinro.tk
