Look at the dock Figure H : Everything with a dot below it is an actually open application, but not all of the dotted items have an active window: Clicking on the red X doesn't quit an application in macOS, and those left running can eat away at resources.

Computers create temporary caches for lots of reasons, mainly to store certain app states, remember your browsing history and passwords, create temp backups of documents you're working on, and more. These files can get huge, and macOS doesn't have any good option for clearing caches out in a centralized location: You either have to know how to do it in a particular app or go about it this way.
The directory that appears is all the caches apps have created on your behalf. You can delete older ones, ones that belong to apps you no longer have, or anything else you're sure isn't important. Just know that doing this is taking matters into your own hands and changes you make could have an impact on important data.
There are two elements of a Mac's memory that can wear with age, but a quick reset can handle problems with both. Both have the same reset steps and are covered in detail by Apple.

If you're facing a problem with your startup disk, you'll need to run First Aid from Recovery Mode — we'll cover this in just a moment. It's straightforward to run a check on your Mac with Disk Utility. You'll quickly be able to identify if any of your disks have issues. Once complete, you'll see a drop-down showing the status; click this to explore.
Disk Utility will try to repair what it can and warn you about errors it found that it can't fix. Although this method checks all disks, we can't repair a broken startup disk from here; for that, we need to run First Aid from Recovery Mode. Quick Tip: If you suspect your Mac disk is failing, CleanMyMac X has many easy-to-use maintenance tools that can help keep your drive running smoothly.
I'll talk you through some of the features later in the article. Or you download the free version now —it's notarized by Apple and completely safe for your Mac. Although Disk Utility checks your startup volume as well, it can't fix any errors if those are found. Running First Aid from Recovery Mode is necessary for repairing your startup disk. So, let's jump straight in:. When you see an Apple logo or spinning globe, release the keys.
Select your startup disk from the sidebar, then click the arrow to view all the containers and volumes. Apple recommends repairing volumes first, then containers, and then the startup disks last. So, from the sidebar, select the last volume listed, then click First Aid at the top, and then Run, working your way up the list for each volume, container, and finally, the disk itself.
This could take a while, so don't be alarmed if it's not over in a couple of minutes; Disk Utility will run its checks and try and repair errors for you.
