Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.

To make room for more storage, it automatically saves files, photos, movies, and email attachments to the cloud.Įach file stays right where you last saved it, and downloads when you open it. Optimized Storage in macOS Sierra and later can save space by storing your content in the cloud and making it available on demand. Starting with macOS Sierra, Apple offered an elegant space-clearing solution feature, Optimized Storage. As you keep installing and using more apps, you have to face space crunch on your MacBook, iMac, or iMac Pro.Īnd, this is why we have to take a few steps to clean your Mac and optimize it for performance. Of course, this isn’t ideal for your Mac storage, either. 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.
