Why Your Mac is Slow/Lagging

Before introducing the ways to speed up your Monterey system, let's take a look at why your Mac is slow or lagging. In fact, many reasons can cause your computer to run slowly. Here are some of the possible factors:

  • Not enough disk space.
  • Resource-hogging processes.
  • Desktop filled with icons.
  • Too many startup items.
  • Incompatible Apps.

8 Proven Ways to Speed up macOS Monterey

Now that we know what factors may cause your Mac to slow down, the next thing we need to do is optimize your Mac based on these possible factors to improve the running speed of your macOS Monterey. 

Free up Storage Space

Insufficient storage space is the most critical factor that causes macOS to be slow. When you are surfing the Internet, watching streaming videos, playing games on your Mac, various caches, logs, junks, and more will be created on your Mac. Over time, these files will take up more and more storage space.

To free up disk space, you can clean up your Mac storage manually or automatically. The manual method is tedious and risky, so that we won't introduce it in detail here. The automatic way is fast, safe, and convenient, and all you need is to download BuhoCleaner, one of the best Mac cleaning utilities. Simple and easy to use, BuhoCleaner allows you to clear cache junks, uninstall unwanted apps, delete app leftovers, find and delete large and duplicate files, and manage startup items without any hassle. Not only that, with the BuhoCleaner Menu widget in the menu bar, you can monitor your Mac performance in real-time and free up RAM with one click.

Reduce Desktop Clutter

Every icon on your Mac desktop is an active window, which means they take up your Mac's memory. So if you want your Mac to run smoothly, then you'd better not put too many files on your desktop.

Restart Mac Regularly

Although Mac's hardware and operating system are designed to work for long periods without rebooting, the longer you run them, the more fragmented your computer's memory becomes and the more problems can occur. Rebooting Mac regularly solves these problems and allows the operating system to upgrade the software automatically. 


Above, we mentioned eight ways to speed up macOS Monterey. Actually, you can also try many other ways, such as resetting PRAM and SMC, adding more RAM, upgrading Mac hardware, re-indexing Spotlight, and more.

All in all, as long as you have enough free disk space, you won't have trouble with slow macOS performance. To free up more space easily and quickly, try BuhoCleaner, which can handle all kinds of cleanup tasks. Make sure you have it downloaded to your Mac. If not, download it from here.
