Remember that this process requires both computers to be on the same network, and the target Mac must be configured to allow remote wake-up in its system preferences.

SSH Access: Connect via SSH and use the `wakeonlan` command to wake the machine

To wake your Mac from sleep remotely using SSH access, you can utilize the `wakeonlan` command, which is a powerful tool for network-based wake-up. Here's a step-by-step guide to achieving this:

First, ensure that SSH access is enabled on your Mac. You can do this by going to System Preferences > Sharing and ticking the box for "Remote Login." This setting allows you to connect to your Mac via SSH from another device. Next, you'll need to know the IP address of the Mac you want to wake. You can find this by checking your network settings or by using the `ifconfig` command in Terminal. Once you have the IP address, you can proceed with the wake-up process.

Open a Terminal window on your local machine and use the SSH command to connect to the remote Mac. The basic syntax is `ssh username@IP_address`, replacing 'username' with your Mac's user name and 'IP_address' with the actual IP. For example, if your username is 'john' and the IP is '192.168.1.100', the command would be `ssh [email protected]`. After entering the correct credentials, you'll be logged into the remote Mac's Terminal.

Now, within the SSH session, you can use the `wakeonlan` command to initiate the wake-up process. The command is `wakeonlan MAC_address`, where 'MAC_address' is the unique MAC address of the target Mac. You can find the MAC address by running the `system_profiler SPHardwareDataType` command in the remote Mac's Terminal. This will display various hardware details, including the MAC address.

For instance, if the MAC address is '00:1A:2B:3C:4D:5E', the command would be `wakeonlan 00:1A:2B:3C:4D:5E`. This command sends a network magic packet to the specified MAC address, which, if the Mac is in sleep mode, will wake it up. Remember to close the SSH session after successfully waking the machine to avoid any unnecessary resource usage.

This method provides a convenient way to remotely wake your Mac, especially in a network environment where multiple machines are connected. It's a useful technique for system administrators or users who need to manage multiple Macs without physical access.

Network Wake: Configure your router to send a magic packet on a specific network

To wake your Mac from sleep remotely using a network-based method, you can configure your router to send a special packet known as a "magic packet" on a specific network. This technique is particularly useful for network-connected devices that don't have built-in wake-on-LAN (WOL) capabilities. Here's a step-by-step guide to setting this up:

Step 1: Identify Your Network and MAC Address

Start by identifying the network you want to use for remote wake-up and the MAC address of the Mac computer you intend to wake. The MAC address is a unique identifier for your computer's network interface card. You can find it in the system preferences or by using the 'network setup' utility on your Mac.

Step 2: Access Your Router's Configuration

Log in to your router's web interface. This can usually be done by entering the router's IP address into a web browser's address bar. Default IP addresses for routers vary, so consult your router's manual or search online for its specific IP address. Once logged in, navigate to the advanced settings or LAN configuration section.

Step 3: Enable Magic Packet Functionality

Look for a setting related to WOL or magic packet. This setting might be under a tab labeled 'Advanced', 'Network', or 'LAN'. Enable the option to send magic packets on the network. You might also need to specify the network interface your router uses to connect to the target Mac.

Step 4: Configure the Network Interface

Identify the network interface your router uses to connect to the Mac. This could be a specific Ethernet port or a wireless network interface. Ensure that the magic packet setting is configured to use this interface. You may also need to set a specific MAC address filter to allow only the target Mac's address to wake the device.

Step 5: Test the Configuration

After making these changes, test the setup by sending a magic packet from another device on the same network. You can use online tools or software that can send magic packets to test the functionality. If successful, your Mac should wake from sleep when you send a magic packet from the configured network.

Remember that the success of this method depends on the network configuration and the compatibility of the target Mac's hardware. Some older or less advanced hardware might not support WOL, so it's essential to check the specifications of your devices before relying solely on this method.

Third-Party Software: Tools like Wake On LAN can wake Macs over a network

This technology allows you to power on a computer remotely over a network, making it an ideal solution for managing multiple Macs in a network environment.

Wake On LAN is a protocol that enables network administrators and users to wake up computers, including Macs, from a sleep state using a network packet. This is particularly useful for IT professionals and system administrators who need to manage and maintain a fleet of Macs in an office or data center. By sending a specific network packet, you can trigger the selected Mac to wake up and resume its operations.

To use WOL with your Mac, you'll need to install a compatible software application that supports this feature. There are several options available, both free and paid, that can facilitate this process. For example, tools like WakeMeOnLAN or Wake-On-LAN-Tools provide user-friendly interfaces to manage and control remote wake-up functions. These applications often require you to install a small agent on the target Mac, which then listens for the wake signal on the network.

When setting up WOL, you'll typically need to configure the network settings on both the computer you're trying to wake and the device sending the wake signal. This includes enabling the appropriate network interfaces and ensuring that the target Mac's hardware supports WOL. It's important to note that not all Mac models have this capability, so checking your computer's specifications is essential.

Once the software and network configurations are in place, you can remotely wake your Mac by sending a specific packet to the target computer's MAC address. This process is straightforward and can be automated, allowing for efficient management of multiple devices. Wake On LAN is a powerful tool for IT professionals, offering a convenient way to manage and maintain remote Macs without physical access.
