What Is an Alias in macOS?
On a Mac, an alias is a special type of file that points to a file or folder. Aliases are similar to shortcuts in Windows and symbolic links in Linux. They’re also dynamic, which means that they will still link to the file or folder, even if you change the original item’s location. An alias can point to a target on your local Mac or on a network machine.
Aliases are handy because you can use them to quickly open a frequently used file or folder without always having to root through folders to find it. When you open an alias by clicking it, the original item opens normally—just as you’d expect it to.
