Check “Cached Files” to know how much RAM is free but ready to use. The “Swap Used” tells if your Mac uses disk space as extra memory. High swap use means low free RAM. Use this data to understand your Mac’s memory health.
Check Ram Via Terminal Commands
Checking your Mac’s RAM using Terminal commands is quick and clear. The Terminal lets you see detailed system info without extra apps. This method works on all Mac models and macOS versions. It helps you find exact memory size and other RAM details.
