Over time, your Mac probably accumulates a lot of cruft. Old applications you no longer use, data you have no use for, a desktop full of icons (only four of which you actually ever use)…you know what I mean. With so many people working from home lately, the problem has only gotten worse.
Now is as good a time as any to tidy up your Mac, freeing up storage space and probably CPU cycles and RAM in the process. Here are a few tips to make quick work of your Mac “spring cleaning.”
They are two distinct entities. Deleting files off disk won't (typically) affect the RAM usage of the machine. RAM is used by running applications, so the easiest way to free up RAM is to quit applications that you're not using. The older PRAM used a small dedicated battery to keep the RAM power up at all times, even when the Mac was disconnected from power. The newer NVRAM uses a type of RAM similar to the flash-based storage used in SSDs to store the parameter information without the need for a battery to keep it safe.
Optimize Storage
Open the Storage Management app, either by using Spotlight (Command-space) or by clicking the Apple logo in the upper left of the menu bar, choosing About This Mac, clicking the Storage tab, then Manage.
In the Recommendations tab you’ll see a number of useful options, like Store in iCloud and Empty Trash Automatically. The Optimize Storage solution will get rid of things like old TV shows you’ve already watched and old email attachments when you’re low on storage space.
Take a look at your Applications and Documents
While you’re in the Storage Management app, click on the Applications tab in the left column. You can see all your installed applications here and sort them by size, easily deleting apps you haven’t used in ages.
Then, click on Documents in the left tab. There are several sections here, like Large Files and Unsupported Apps, that are worth perusing. Big library files (for apps like Lightroom or Final Cut Pro) are likely to show up here, and you might not want to mess with them. But you may have old large files and documents, or apps that no longer even work on your version of macOS, that you can safely remove.
How To Clean Up Ram On Mac Hard Drive
Get your desktop under control
If your desktop is littered with icons, you should probably tidy things up a bit. Right-click (two-finger tap on a trackpad) any open space and choose Clean Up to get things arranged neatly, or Clean Up By to sort them as well. Consider the Use Stacks feature to automatically stack-up files of the same type into a single icon. Just click on that icon to open the stack. This can really tidy up your desktop!
