In a way, we can denied list or allowed list certain computers based on their MAC address. It helps in preventing unwanted access to the network. It helps in listing a set of allowed devices that you need on your Wi-Fi and the list of denied devices that you donвЂ™t want on your Wi-Fi. In this, each address is assigned a 48-bit address which is used to determine whether we can access a network or not.

MAC filtering is a security method based on access control. Each adapter has a distinct label known as a MAC address which recognizes and authenticates the computer. A wired adapter allows us to set up a connection to a modem or router via Ethernet in a computer whereas a wireless adapter identifies and connects to remote hot spots.

To reset the SMC on a portable Mac without a removable battery, complete these steps instead:Дў. Reconnect the battery and MagSafe power adapter.Д§. Press and hold the power button for 5 seconds.Д¦. Disconnect the MagSafe power adapter from the computer, if it's connected.Д¤. To reset the SMC on a portable Mac with a removable battery, complete the following steps:Дў. A computer that supports target display mode switches into or out of target display mode at unexpected times. A computer that supports target display mode does not switch into or out of target display mode as expected. The computer is running unusually slowly although it is not experiencing abnormally high CPU utilization. The MagSafe power adaptor LED doesn't appear to indicate the correct activity. The battery does not appear to be charging properly. The computer sleeps or shuts down unexpectedly. A portable Mac doesn't appear to respond properly when you close or open the lid. The computer doesn't respond to the power button when pressed. The display backlight doesn't respond correctly to ambient light changes on Mac computers that have this feature. Battery indicator lights, if present, appear to behave incorrectly (on portables that use non-removable batteries). The Status Indicator Light (SIL) appears to behave incorrectly (on Mac computers that have an SIL). The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature). The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated. The System Management Controller (SMC) on a Mac can sometimes cause unusual system behavior, such as:

Reset the System Management Controller (SMC) Hold the keys down until the computer restarts and you hear the startup sound for the second time. You must press this key combination before the gray screen appears.ДҐ. Press and hold the Command-Option-P-R keys. You will need to hold these keys down simultaneously in stepД¤. Locate the following keys on the keyboard: Command, Option, P, and R. To reset the PRAM and NVRAM, weвЂ™ll do the following for Intel-based Macs:Дў.
