Your MacBook Getting Slow? Here Are Simple Fixes

After a long time, your Mac can become slower than usual due to the accumulated cruft clogging up your computer system, such as temporary files, caches, streaming data and so on Apart from the low disk space, lack of RAM can be the second major cause of slowdown problems.

When opening an app on your Mac, its binary will be loaded from the storage into the RAM so that the CPU of your computer can fetch and execute code. Similar to multitasking operating systems, macOS will manage the RAM memory on your behalf you can run more apps at the same time than fitting into it.

The memory management on MacOS works very well, most of the time, and the Activity Monitor app will automatically slow RAM when it’s nearly 100% utilized. The RAM wants to be packed to the gills all the time since loading content from internal storage is much slower than fetching from the RAM.

However, due to some reasons, the memory management on MacOS fails to purge loaded content from the RAM memory. The operating system flushes the system caches, but caches may not be properly emptied in some cases. This will cause your Mac to start stuttering and showing up signs of slowdown performance like longer app loading times and slower multitasking operations. If you are facing the same difficulty, here is how to manually force your MacOS to tidy the RAM and flush the hard disk caches.
