The other problem is that these files may take up a lot of space from your Mac. However, if you are into jobs like video editing, software testing or development, the junk file can slow down your Mac. Now, if you use your Mac for simple tasks like web browsing or checking email, this won’t be a problem. Just like Windows, macOS also generates temporary/junk files over time. It took me, however, a few months to understand why Macs also need cleaning and performance-boosting. Of course, that didn’t last long.Īs I started using my Mac for resource-intensive tasks and more apps, it started becoming somewhat slow. However, I had this false idea that Mac devices don’t need cleaning or maintenance as such. Like many of you, I shifted from Windows to macOS to get superior performance and smooth experience.
