Oct 22, 2019 Your trusted Apple devices are available to review under Apple ID on Mac. For each, you'll find a link to Find My on the web. There's also a button to use to remove Apple Pay from the device (s), when applicable. You can also remove the devices from the same location.
Open a Mac app from an unidentified developer. If you try to open an app that isn’t registered with Apple by an identified developer, you get a warning dialog. This doesn’t necessarily mean that something’s wrong with the app. For example, some apps were written before developer ID registration began. How to find the MAC address in Mac OS. Go to Utilities (Finder Utilities OR command + shift + u) and start the Terminal app. Type this in the Terminal: networksetup -listallhardwareports You will be a list of all the network interfaces with their MAC addresses (Ethernet Address).

Identifying MAC Addresses
Objective:
2.1 Identify a MAC (Media Access Control) address and its parts.
This chapter many times refers to MAC addresses and how certain devices use them. However, it has not yet discussed why MAC addresses exist, how they are assigned, and what they consist of. Let’s do that now.
A MAC address is a 6-byte hexadecimal address that allows a NIC to be uniquely identified on the network. The MAC address forms the basis of network communication, regardless of the protocol used to achieve network connection. Because the MAC address is so fundamental to network communication, mechanisms are in place to ensure that there is no possibility of duplicate addresses being used.
Identify For Mac Computers
To combat the possibility of duplicate MAC addresses being assigned, the Institute of Electrical and Electronics Engineers (IEEE) took over the assignment of MAC addresses. But rather than be burdened with assigning individual addresses, the IEEE instead decided to assign each manufacturer an ID and then let the manufacturer further allocate IDs. The result is that in a MAC address, the first three bytes define the manufacturer, and the last three are assigned by the manufacturer.
For example, consider the MAC address of the computer on which this book is being written: 00:D0:59:09:07:51. The first three bytes (00:D0:59) identify the manufacturer of the card; because only this manufacturer can use this address, it is known as the OrganizationalUniqueIdentifier(OUI). The last three bytes (09:07:51) are then referred to as the Universal LAN MAC address: They make this interface unique. You can find a complete listing of organizational MAC address assignments at http://standards.ieee.org/regauth/oui/oui.txt.
You can discover the MAC address of the NIC in various ways, depending on what system or platform you are working on. Table 3.4 defines various platforms and the method you can use to view the MAC address of an interface.
Table 3.4 Methods of Viewing the MAC Addresses of NICs
Platform | Method |
Windows 95/98/Me | Run the winipcfg utility |
Windows 2000/2003/XP | Run ipconfig /all from a command prompt |
Linux/some Unix | Run the ifconfig -a command |
Novell NetWare | Run the config command |
Cisco router | Run the sh int <interface name> command |
Figure 3.28 shows the ipconfig /all command run on a Windows 2000 system. The MAC address is defined on the Physical Address line of the output.

The new Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app on iOS, iPadOS, and now macOS. Find My can help you locate your devices and your friends and family. And now it can help you find your devices even when they’re offline.
Locate your devices easily.
You take your devices everywhere. Which means you might leave them anywhere. Whether they’re in a conference room or under a sofa pillow, chances are they won’t be lost for long. The Find My app helps you locate not only your iPhone, but also your iPad, iPod touch, Mac, Apple Watch, or AirPods.
See all your devices on a map.
Is your iPad at home or back at the office? Use the map to get a full picture of where your devices are — and where a missing one might be. Some devices can also mark their location when the battery is critically low, to help you find them even if they run out of power.
Play a sound to
find your device.
When you can’t find something but think it’s nearby or around others who might hear it, you can play a sound to pinpoint its location. Your AirPods have a specifically designed sound that can project across a room — and even farther.
Put it in Lost Mode.
If your device goes missing, put it in Lost Mode to lock it immediately and start tracking its location. You can also display a message with a contact number on your device’s Lock screen, so whoever finds it can call you without accessing the rest of its information.
Erase it with ease.
Worried that your device has fallen into the wrong hands? You may want to erase it remotely to delete your personal data and restore your iPhone, iPad, iPod touch, Mac, or Apple Watch to its factory settings. If you retrieve it, you can restore it from your iCloud backup.
Locked down. Automatically.
Activation Lock is designed to prevent anyone else from using or selling your device.* When you enable Find My on your device, Activation Lock is turned on automatically. Your Apple ID and password will then be required before anyone can erase your device or reactivate it.
Find your devices.
Even when they’re offline.
Find My can help you locate a missing device — even if it’s offline and sleeping — by sending out Bluetooth signals that can be detected by Apple devices in use nearby. These devices then relay the detected location of your device to iCloud so you can locate it in the Find My app. It’s all anonymous and encrypted end-to-end so no one, including Apple, knows the identity of any reporting device.

Keep up with the
people in your life.
Invite friends and family members to share their locations. So you can keep in touch with one another, coordinate around an event, or know when a family member has arrived home safely.
Put your friends and family on the map.
When you share your location with friends, you’re all in the loop. Find each other more quickly and stay connected with ease. Share your location for an hour, a day, or indefinitely as you see fit.
Get notifications
based on location.
You can set up notifications for when friends and family leave or arrive at a place — making meetups a cinch. And so no one’s privacy is compromised, they’ll be notified when you set one up. You can also use parental controls to set up alerts and notifications, so you know when your child has arrived at a friend’s house or departed from school.

Your location data
stays private.
Just like every Apple product, Find My is designed to keep you in control of your data. Apple receives location information only when you actively locate your device, mark it as lost, or enable Send Last Location. Location data is retained for a maximum of 24 hours and is fully encrypted on Apple’s servers. And when Find My is used to locate an offline device, everyone’s information is protected with advanced end-to-end encryption so that no one, including Apple, knows the location or identity of any of the participating users or devices.
