How to Output Stereo Audio in Mono

  Matt Cone       January 5, 2021

Recently I replaced my aging Bose QC25 headphones with a pair of AirPods Pro headphones. Both products are a major upgrade from the stock earbuds that ship with iPhones, but the high-quality audio output also means that you can hear every imperfection in the music. For example, older tracks that were recorded in mono sometimes have output that is only audible in one channel, which means that you can only hear the music in one ear.

How to Force Quit Mac Apps

  Matt Cone       January 4, 2021

Under normal circumstances, you can quit applications on your Mac by pressing the Command and Q keys or selecting Quit from the application’s menu. But sometimes an application is frozen and just won’t quit. When that happens, you can force quit the application on your Mac to completely close it. Here’s how to force quit Mac apps: From the Apple menu, select Force Quit. The window shown below appears.

How to Change Your Mac's DNS Servers

  Matt Cone       January 4, 2021

Your Mac uses something called the Domain Name System (DNS) to access websites. It’s a system invisible to you, the user, and most people don’t even know it exists. But if the DNS servers you’re using are slow or unavailable, websites will load slowly or won’t load at all. That’s why it’s important to learn about DNS and consider changing your DNS servers. In this tutorial, we’ll show you everything you need to know about DNS to speed up surfing and ward off potential problems.

How to Switch the Control and Command Keys

One of the most subtle differences between a Mac and a PC is also one of the biggest: the functionality of the control key on the keyboard. When you buy a Mac, you’ll need to start using the command key instead of the control key. For example, instead of pressing Control-S to save and Control-C to copy like you did in Windows, you’ll have to press Command-S and Command-C to do the same thing in macOS.

Your Mac contains thousands of hidden files and folders that you’ll probably never need to access. We explained how to access all hidden files and folders in another tutorial, but there’s an easier way to access one of most important hidden folders on your Mac, called the Library folder. The user’s Library folder, which is different than the root Library folder at the top-level of the hard drive, contains hundreds files that store important preferences and settings for many of the applications on your Mac.

How to Change Your Mac's Startup Disk

  Matt Cone       January 3, 2021

When your Mac turns on, it loads the operating system on the designated startup disk, a hard disk or partition containing the macOS operating system. Normally, the startup disk is set as the hard disk inside of your Mac, but you can use an external hard drive, USB thumb drive, or DVD as your startup disk. Changing Your Mac’s Startup Disk with System Preferences Here’s how to change your Mac’s startup disk:

How to Find Your Mac's MAC Address

  Matt Cone       March 21, 2013

Each of your Mac’s network interfaces — such as the ethernet and Wi-Fi cards — have a permanent, unique serial number called a media access control (MAC) address. Some universities and employers may request your Mac’s MAC addresses to monitor or limit your access to certain networks. MAC addresses can also be used for less nefarious purposes. For example, if your computer is stolen on a university’s campus, the IT department may be able to use its MAC address to trigger an alert when the criminal connects your computer to a university network.

How to Set a Static IP Address in Mac OS X

  Matt Cone       March 15, 2013

When your Mac is connected to a private network in a home or office, it’s probably assigned what’s known as a dynamic IP address. (To check, see How to Find Your Mac’s IP Address.) That’s not a problem for the majority of users - most people don’t care whether their IP addresses changes or not. But dynamic IP addresses won’t work for certain tasks like port forwarding, dynamic DNS, or client-to-client file sharing on the local network.

How to Configure Network Locations in OS X

  Matt Cone       March 14, 2013

Your Mac allows you to save and quickly switch between multiple network configurations, which are referred to as network locations in OS X. This is a useful feature for users who need to set network-specific proxies, DNS servers, or static IP addresses. You can also use network locations to specify settings for specific network interfaces, such as an Ethernet card, Wi-Fi or Bluetooth connection, and even VPN. Once you’ve created and saved different network locations, you can switch between them by using the Apple menu or System Preferences.

How to Find Your Mac's IP Address

  Matt Cone       March 11, 2013

Your Mac is assigned something called an IP address when it connects to a network. Other devices that are connected to the same network can use this unique identifier to transfer information to and from your Mac. If this sounds confusing, it might help to think of an IP address as your Mac’s home mailing address. Just like physical mail, which is routed to your home via a unique address, digital information is routed to your Mac using an IP address.
