How to speed up a sluggish Mac
If you're just looking to speed up your Mac, there are other alternatives to defragging. The easiest tip to a speedy Mac is to close apps that you aren't using - they're usually noticeable by a dot underneath their icon on your Dock. To quit an application you're not using, simply right click the icon and click quit.
Targeting those pesky apps that start up when you turn your Mac on can also combat a sluggish system - if you don't need them, you can stop them from opening. Simply open your System Preferences, head to Users and Groups and select Login Items. From there you can see a list of all applications that open on startup and by deselecting them, you'll stop them from opening.
Another important tip is to try to leave at least 10 percent of your overall HDD space free to keep your Mac running smoothly. It needs free space to perform background actions. Make sure that once you've deleted your files, you empty the Recycling Bin, as no free space will be added until everything is permanently deleted.
If you're looking for software that can do all of those things for you and more, try iMobie's MacClean, which offers a limited free version available to download here.
