Apple operating systems are constructed using a Linux file system hierarchy, which means that traditional UNIX system directories hide certain files and directories. Unlike Applications or Documents or Downloads, some files and folders are hidden by default by the Mac operating system macOS.
MacOS hides these for good reason. When buildings are constructed, wiring and plumbing is hidden behind walls. As a general rule, exposing anything that could have a serious negative impact on a building if it was accidentally damaged or tampered with is considered a good idea. The same is true of usr and var and other folders and directories. Within the usr is user-land programs and data is contained, such as user binaries, their documentation, libraries, header files, and other read-only programs and associated data.
Generally speaking, because these folders and directories are behind the scenes, most users - even Mac power users - don't need to know about them or gain access. Another way to make sure everything is working smoothly under the hood is to download a Mac performance improvement app, such as CleanMyMac X. It can take a quick look at what is taking up too much space on your hard drive, with its Space Lens feature. Once CleanMyMac X has analysed your files and directories, including those that are hidden from view, you can delete what it recommends and regain the space you need for your Mac to run smoothly and quickly.
With the Space Lens tool, you can also access the usr folder and see how much space it takes on your Mac and what files it includes. First, you have download and install CleanMyMac X and then follow such steps:. However, if you prefer the manual way of looking behind-the-scenes, here is how you can access the usr folder on a Mac. Only attempt this method if you are comfortable using Terminal.
Remember, using Terminal can make significant changes to your macOS systems and files, so only make changes this way if you consider yourself a Mac power users. This method should temporarily uncover the usr folder. Accessing the usr folder is often only necessary if you are looking for ways to improve the performance or speed of your Mac. Thankfully, there is an easier way. Downloading CleanMyMac X can solve a lot of problems, quickly and safely, without any risk of causing accidental damage.
It comes with a useful Space Lens feature, since one reason a Mac doesn't perform as well as it once did is a result of files taking up too much space, or duplicate files, folders or apps.
