Resetting an Apple ID password can be annoying, though it’s made much easier if you have access to a device that you are already signed into. Without another device though, the process of resetting an Apple ID account login can be frustrating, but a Recovery Key makes this situation easier.
Apple ID Recovery Key serves as an additional way of authenticating your Apple account, and it can be used if you forget your password and lose access to another trusted device. Using a recovery key eliminates the need to visit Apple’s website to jump through hoops like verifying payment method details and answering security questions for a password reset. The ability to generate a recovery key from the Mac requires macOS Big Sur or macOS Monterey.
If you have a Mac, it’s pretty easy to generate and use a recovery key.
• Open “System Preferences” on the Mac (from Apple menu or Dock).
• This will open a new window on your Mac. Click on the Apple ID option located at the top-right corner.
• Now, click on “Password & Security” from the left pane. In this section, you’ll find the Recovery Key option below Trusted phone numbers. Click on “Turn on” next to the Recovery key option to continue.
• When you’re prompted to confirm your action, click on “Use recovery key” to proceed.
• Next, you’ll be asked to enter your Mac user password. Type in the password and click “OK”.
• If you have an iPhone, you’ll also be prompted the enter the passcode you use to unlock your iPhone.
• Now, your unique recovery key will be shown to you on the screen. Make sure to write it down in a safe place that you’re able to easily access. Once you’re done, click on “Continue”.
• Next, you’ll be asked to enter your 28-character recovery key to verify that you’ve noted it down. Click on “Done” after typing it in.
• The feature is now turned on. If you want to change the recovery key for any reason, you can click on “Create new key”. You also have the option to turn this feature off at any time.
From now on, you’ll have just two ways to reset the password for your Apple account. You can either reset the password from a device that you’re already logged into, whether it’s your Mac, iPhone, or iPad, or you can use the recovery key instead. The latter could prove to be invaluable if you don’t have access to another trusted device, or if you only have one Apple device.
Note that when you disable and re-enable the Recovery Key feature, a completely new key will be generated for your account. If you lost your current recovery key somehow, you can replace the key with a new one on your Mac from the same menu using the “Create new key” option.
If you're having persistent networking issues on a Mac, like constantly dropping from a Wi-Fi network, inability to join networks, inappropriately sluggish internet connections that only impact the particular Mac, or other networking related issues, it may be helpful to reset the network settings.
The easiest way to reset Wi-Fi settings is to delete Wi-Fi related configuration files. Please note that by resetting network settings you will need to re-add and re-join any networks and enter the passwords again.
• Disable Wi-Fi by pulling down the Wi-Fi menu and choosing to toggle the Wi-Fi switch Off
• Go to the Finder, pull down the "Go" menu, choose "Go to Folder..." and enter the following path:
/Library/Preferences/SystemConfiguration/
the click the "Go" button
• Select and delete the following files from this folder:
com.apple.airport.preferences.plist
com.apple.network.identification.plist
com.apple.wifi.message-tracer.plist
com.apple.network.eapolclient.configuration.plist
NetworkInterfaces.plist
preferences.plist
• Restart the Mac by going to the Apple () menu and choosing "Restart..."
• When the Mac boots back up, enable Wi-Fi again by going to the Wi-Fi menu and toggling it back On
• Select the network you wish to join
This approach will often resolve many wireless networking issues encountered on the Mac, but if you're still experiencing any Wi-Fi networking issues, you might want to reset the router and the modem itself, which typically involves unplugging those devices from power source for 10-15 seconds and then plugging them back in again, then waiting a few minutes for those to rejoin the appropriate networks.
If you need to quickly offer help to another Mac user you know, there's no quicker way to remotely provide assistance than via Apple's own Messages. Here's how to take control of another person's Mac on their behalf, and how to allow others to do the same to your desktop.
As part of the Messages app in macOS, it is possible to establish a remote desktop session where you have control of a Mac across the Internet or someone else has control over your Mac desktop. What's more, as well as being simple to get going, it also doesn't require any real installation of extensions or other components.
What does Messages' screen sharing feature do? When a screen share is initiated, the screen from the Mac being controlled will be streamed as a live video feed to the other participant, the Mac that will be used for control. This will allow the user on the controlling Mac to see what is on the desktop of the Mac being controlled. At the same time, a FaceTime Audio call is started between the two users, providing two-way audio. This enables the users to speak to each other, such as advising on what they are doing for the other user or additional instructions. The feature doesn't automatically enable the ability to remote control the other person's display by default, but the option is presented. If control isn't provided by one party to the other, the screen is shared but it is not remotely controllable.
To share your screen with another user:
• Open Messages on your Mac.
• Select the conversation with the person you want to share the screen with. If no prior conversation exists, send a message to them.
• In the main menu, select Conversations then Invite to Share My Screen. The sharing and audio call will begin automatically once the remote user accepts the invitation.
To request another user shares their screen:
• Open Messages on your Mac.
• Select the conversation with the person you want to share the screen with. If no prior conversation exists, send a message to them.
• In the main menu, select Conversations then Ask to Share Screen. The sharing and audio call will begin automatically once the invitation is accepted.
Once sharing is enabled, a new window appears called Screen Sharing, which will host the call and show the sharing user's desktop. There are also some options within the window that can be used. Clicking the mouse pointer icon in the menu will send a request to the sharer to enable remote control of the Mac. Clicking on the remote display will highlight elements on the shared Mac, which can be useful for pointing out elements of an app's interface without taking control. When you have control of the remote Mac, you can also control the Clipboard, which means you can copy and paste text and images between the two computers. This is handy to save you from retyping a URL into a remote browser when you have the link locally. You can even transmit files from the remotely-controlling Mac to the shared Mac by dragging and dropping them onto the window.
To end a screen sharing session:
• For the screen-sharing Mac, click the Sharing icon in the menu bar then End Screen Sharing. Alternately, you can select Pause Screen Sharing if you want to stop for a while.
• The remote controlling Mac can do the same by selecting Screen Sharing in the menu followed by Quit Screen Sharing.
If screen sharing doesn't work, make sure the user of the Mac being shared is signed in to iCloud on that Mac using the same Apple ID that they are using for messages. If they are using different IDs, add both Apple IDs to the same contact within the Contacts app and try again. Also, make sure that they are not limited by Screen Time. If one party is restricted and the initial Messages communication cannot be established, that could prevent Screen Sharing from functioning properly.
Wireless interference can cause Wi-Fi and Bluetooth devices to disconnect or perform poorly. Bluetooth enabled keyboards and mice may not pair or connect consistently, or audio from Bluetooth enabled earphones or speakers may be choppy, but you can take steps to reduce or overcome it.
Any of these symptoms could be caused by interference affecting the Wi-Fi or Bluetooth signal:
• Device doesn't connect or stay connected
• Connection is slow and signal strength is low
• Bluetooth audio skips, stutters, cuts off, or has static or buzzing
• Pointer movement is erratic or jumpy
These general steps can help achieve a cleaner, stronger wireless signal:
• Bring your Wi-Fi device and Wi-Fi router closer together. Bring the Bluetooth devices that are connecting to each other closer together.
• Avoid using your wireless devices near common sources of interference, such as power cables, microwave ovens, fluorescent lights, wireless video cameras, and cordless phones.
• Reduce the number of active devices that use the same wireless frequency band. Both Bluetooth and Wi-Fi devices use the 2.4 GHz band, but many Wi-Fi devices can use the 5 GHz band instead. If your Wi-Fi router supports both bands, it might help to connect more of your Wi-Fi devices to the 5GHz band. Some dual-band routers manage this for you automatically.
• Configure your Wi-Fi router to use a different Wi-Fi channel, or have it scan for the channel with the least interference. Most routers perform this scan automatically on startup or when reset.
If you're using USB 3 devices with your computer, you can limit their potential to interfere with nearby wireless devices:
• Use a high-quality, shielded USB cable with each USB 3 device.
• Move your USB 3 devices—including any USB hubs—farther away from your wireless devices.
• Connect USB 3 devices to the ports farthest from your computer's Wi-Fi antenna. For example, if your computer has ports on the back, prefer the USB ports closest to the middle. If your computer has ports on the side, prefer the USB ports closest to the front.
• Turn off any USB 3 devices that aren't in use.
Avoid physical obstructions in the path of your wireless signal. For example, a metal surface between your Bluetooth mouse and computer could cause the mouse to perform poorly, and a metal-reinforced concrete floor between your Wi-Fi router and Wi-Fi device could cause poor Wi-Fi performance.
• Low interference potential: wood, glass, and many synthetic materials
• Medium interference potential: water, bricks, marble
• High interference potential: plaster, concrete, bulletproof glass
• Very high interference potential: metal
There is a whole jungle of apps out there that show you the status of your computer in the menu bar, on your desktop or in the Dock, but did you know that the best tool of them all comes with macOS?
Activity Monitor is an application that allows you to monitor exactly what is going on with your computer at all times by showing you how much memory, cpu, network and disk space is currently being used. It can also show you which application is using the resources and it allows you to quickly kill a process that is going haywire or has stopped responding.
The handiest feature of all is that it can show the status in the Dock so that you can quickly see if something has gone wrong and prevent crashes. Open up Activity Monitor (in Utilities inside Applications), then select the type of information you want from the View, Dock Icon menu. To make the most of this we’d recommend setting Activity Monitor to automatically launch when you log in. This is done by right clicking the icon in the Dock and choosing Options, Open at Login.
Keeping Activity Monitor in the Dock also has all sorts of unexpected benefits, for example it is very handy if you feel that your computer is getting slow. Most Macs that are kept in good shape can live for many years and still be as fast as the day they were purchased. The key to this? Keep an eye on the memory usage.
If all the memory is being used up soon after booting up your computer macOS will start using the hard drive to give you more memory than what is physically available (this is called swapping). The catch is, swap memory is much much slower than real RAM memory so you will notice this by feeling that the computer gets much slower. The solution? Use Cocktail to purge inactive memory (System > Memory), try cleaning up the applications that run in the background or install more memory.
Activity Monitor can also help you debug other problems. Battery life is directly dependent on how much load there is on the processor so if the battery in your laptop doesn’t last as long as you expect, have a look at how the processor is being used. Generally, to get anywhere near Apple’s specified battery life you should be around 10-20% usage so if the processor is averaging more than that some process is draining your battery.
