![]() This is by design-as a rule of thumb, the RAM wants to be packed to the gills all the time because loading content from storage is slower than fetching from the RAM. MacOS’s memory management works pretty well-most of the time, the Activity Monitor app shows the RAM as being nearly 100 percent utilized. Like all multitasking operating systems, macOS dynamically manages the RAM on your behalf so that you’re able to run more apps at the same time than fit into it. When you open an app, its binary gets loaded from storage into the RAM so that the CPU can fetch and execute code. If you’re having issues with certain apps, it may also be time to clear your cache.Over time, your Mac can start performing slower than usual due to the accumulated cruft clogging up the system, including temporary files, various caches, streaming data and so forth.Īside from low disk space, the RAM (or lack of it) is the second major cause of slowdowns. There are a few different types of cached data: user or app data that saves information for certain apps system cache, which your operating system uses to save process information and browser cache, which saves your web browsing activity.Ĭonvenient, right? But it’s important to clear this cached information every now and then to keep your data safe and free up disk space, which helps your operating system run more smoothly. That way, your computer doesn’t have to spend time downloading all of that information again - it can just pull it from the cache. When you visit that same site in the future, your browser simply (and quickly) loads data from the folder it's already created. When you visit a website, for example, your browser will download data like images, scripts, and login credentials and save it all in a cached folder. This is called caching, which, as Apple (Opens in a new tab) puts it, “helps reduce internet data usage and speed up software installation on Mac computers, iOS and iPadOS devices, and Apple TV.” Many of your daily computer activities - like opening programs, logging onto email, and navigating websites - are saved as temporary files within your computer. ![]()
