How to Make an Alias (Shortcut) on a Mac

  January 7, 2021

If you’ve ever wished you could have a single folder in two different places at once, you should consider creating an alias, which is known as a shortcut on Windows-based operating systems. An alias looks like a folder, but when you double click it, you open the actual folder it points to. It’s literally a shortcut to a different directory on your Mac. Many people create aliases for their most commonly used folders, such as Documents or Applications, and move those aliases to the Desktop.

How to Find Your iPhone's IP Address

  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

  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.
