How to Find Your iPhone's IP Address

  Matt Cone       January 6, 2021

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

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.

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.

How to Switch the Control and Command Keys

  Matt Cone       January 3, 2021

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.

  Matt Cone       January 3, 2021

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.
