When you quit applications on Mac, it takes time to release wired memory. You can quit such programs to free up RAM on Mac. What you can interfere with are the kernel-level drivers and apps such as antiviruses, or virtual machines. Users have little to do with wired memory, given that this portion of memory mainly relates to the kernel, which is essential for system operations. How to clear wired memory on MacĮven if the high macOS wired memory doesn't affect the normal operation of the Mac, you may want to clear high macOS wired memory to reclaim more available RAM for applications. Green memory pressure means the RAM is used efficiently. It is accurately measured by examining the amount of free memory available, the swap rate, and the amount of wired and cached memory. Instead, the memory pressure on the left side is the indicator of the memory health of your Mac. But you don't need to worry about the high macOS wried memory as long as the Mac function well. Given that the wired memory cannot be paged out to a hard disk and takes up the limited RAM, the higher the wired memory, the less free RAM for other applications. As some user applications modify the macOS kernel and increase wired memory on Mac, hence too many running applications/programs could lead to a high macOS wired memory. This part of memory is created by the system operations. To the right, it shows how the used memory allocates, including app memory, wired memory, and compressed.įor a MacBook with 8GB of RAM, the wired memory usually occupies around 2GB.Read the chart on the bottom, and find Memory Used, it tells the amount of the used RAM.Choose the Memory tab on the top of Activity Monitor.In Finder, choose Applications > Utilities > Activity Monitor, and launch this utility.Understand what macOS wired memory is now? Share it with more people! Unlike other inactive memory which could be cached to the hard disk to release more RAM for other programs, so-called swap memory, the wired memory cannot be moved to your hard drive from RAM given that apps or system needs immediate access to it. Thus, it varies depending on the apps you are using. Although user applications don't directly work with it, some send requests to kernel drivers such as virtual machines like Parallel desktop and VMWare, tapping into the wired memory. It stores data for virtual memory objects, virtual memory and I/O buffer caches, various drivers, etc. The wired memory on Mac, also called resident memory, is reserved for the macOS kernel and its data structure. In this post, we will learn more about macOS wired memory. The RAM, the physical memory, consists of several parts, and wired memory is one of them. RAM(Random Access Memory) is a mechanism used by modern computers to store data of running programs, it is directly accessed by the processor to deliver fast and smooth performance on your devices.
