How to speed up your Mac

These tips and tricks will get your Mac running like it should

None of us like to see the spinning beach ball of death. Here’s a quick guide for how to speed up your Mac, without shelling out a fortune for additional RAM or a faster hard drive.

Apple’s operating system is good about optimizing itself, but that doesn’t mean there’s nothing you can do to speed up a slow system. Let’s dive in!

Update your Mac’s software

First things first — make sure your Mac is up-to-date. The latest security patches are essential to keeping your Mac running well, and Apple is pretty good about optimizing new releases for better performance. Click the Apple icon in the upper-left corner of you display and select App Store to head to the App Store.


Next, select Updates in the left-hand column and click the Update All button. If you’re using a MacBook, plug it in before doing this. The process will update MacOS and most of your apps, ensuring they take advantage of the most recent security patches and optimizations.

Use the Optimize function

Mac Optimize Storage

Ever since MacOS Sierra, Apple’s operating system has had an option called Optimize Storage that can help clear space and improve speed.  First, click the Apple icon in the top-left corner of the screen and go to About this Mac. From here, choose the Storage tab and then select Manage.

This will give you a number of useful tools, including ways to store all files in iCloud and spot clutter you can get rid of (keep the window open when trying out our other tips). However, the most useful one for you right now is the Optimize Storage option. This allows you to do handy things like remove watched TV shows, only download recent attachments, and so on. Try out this tool if you consume a lot of media on your Mac!

Do a quick malware scan

The whole “Macs don’t get viruses” thing is a myth. While it’s true that MacOS has certain security advantages because the vast majority of malware targets Windows users, Macs are still prone to the occasional intruder. In fact, when we asked the experts they all recommended getting an antivirus app for your Mac. Thankfully, there are tons of free options designed to keep you safe, from around-the-clock scanners to one-time tools.

If you don’t know what to pick, Malwarebytes for Mac offers a free one-time scan that catches and removes the most common malware found on the platform. It’s also quick at doing so.

Disable login items

If your Mac takes forever to start up, there’s a good chance you’ve got way too many apps loading up with your system. Disabling these login items will not only speed up the booting process, but potentially free up system resources and speed up your system as a whole.

To begin, open System Preferences, which you can find by clicking the Apple icon in the left-hand side of the menu bar. Once there, click Users & Groups and select the Login Items tab to see a list of apps that start up when your Mac does.


If you see any that you don’t need, select them in the list and click the minus button at the bottom of the screen.

Disable transparency

The splash visual effects of MacOS have been in place ever since Yosemite, but some of them aren’t on the side of speed. Transparency is the biggest culprit. Everything is transparent now, which is why the menu bar takes on some of the colors from your wallpaper, among other things. While El Captain really reduced the impact of these effects on performance, there’s still a pretty big productivity gain to be had by turning them off, even on the most recent update.

The option to do so exists, but is slightly hidden. Head to System Preferences and select Accessibility. Under Display, click Reduce transparency so it’s checked.


User interfaces will stop using the transparency effect once deactivated, and run a lot quicker too.

Clear out your caches

If you regularly use your Mac, odds are it’s building up all sorts of cruft over time. That’s taking up space on your hard drive, and could also be slowing down your apps.

Web browsers, with their backlog of history and massive caches, are famous for this, which is why it’s a good idea to clear your cache from time to time. But they’re not the only apps that build up caches and other files over time, which is why we recommend you check out CCleaner for Mac.


This free app can simultaneously clear out your browsers’ caches and the caches your system builds up over time. Keep in mind that the company also offers a premium version of the software on its site, but the free version is more than adequate for most users.

Uninstall software you don’t use

Freeing up space on your boot drive can increase performance, particularly if your drive is nearly full (this is especially true for older Macs without SSDs). An easy way to save a bunch of space is to delete apps you don’t use anymore. If you’re the kind of person who installs a load of apps and then forgets about them, it’s time for a journey.

Click Go in the menu bar and head to the Applications folder and delete unneeded apps. But don’t just drag your applications to the Trash icon — that will leave behind a bunch of stuff you don’t need. Instead, look into the free application AppCleaner.


Drag any app to this window and you can also delete all related files, including caches and configuration files. Or, if you prefer, you can browse a complete list of your apps and delete them from there.

This is the best way to ensure an application you don’t want anymore isn’t leaving anything behind, so get to it, and clean out that Applications folder. You can also use Activity Monitor to look for software that’s taking up a lot of RAM.

Find and delete unnecessary files

Apps probably aren’t taking up most of the space on your drive. Instead, that honor is likely held by your files. But which ones? The free application Grand Perspective gives you a birds-eye view of your files, with the largest files taking the form of the biggest blocks. Explore this and see if there are any large files you want to delete or move to an external hard drive for long-term storage.


Clean up your desktop

Here’s a quick tip: if your desktop is a cluttered mess of icons, clean it up. Your desktop is a window like any other, so if it’s so overwhelming you can’t find files, it’s also probably slowing down your system. Even putting everything on your desktop into a folder can help, if you’re too overwhelmed to actually sort everything.

Disable the Dashboard

If you’re running an old version of MacOS, you can disable the Dashboard. It was fun back in 2005, but these days a collection of widgets that take up the entire screen just amounts to unnecessary clutter. Head to System Preferences, then click the Mission Control icon and turn off the Dashboard.


Note that the Dashboard is automatically disabled in MacOS Mojave and has been removed completely in MacOS Catalina, so you don’t have to worry about it if you’re on the latest version of MacOS.

Actually close apps

This is kind of Mac 101, but don’t be embarrassed if you don’t know this (lots of people don’t). When you hit the red “X” circle in the upper-left corner, it doesn’t close the app, it just closes its main window. The app itself is actually still running — you can tell because a glowing dot still rests beneath the application in the dock.


To properly close an app, right-click the icon and select Quit. Alternatively, you can close apps using the keyboard shortcut Command+Q, which shuts down any app. Having too many apps open can seriously slow down your system, so make closing apps a priority.

Run OnyX if things are still slow

Did none of these tips work? Let’s get out the big guns, then. OnyX is a free app that runs all sorts of Mac-centric optimizations. Download the appropriate version for your system, then install it and start it up. This is a power user’s tool, and probably shouldn’t be used by anyone who isn’t comfortable with that.


First, Onyx will verify your hard drive, which is already useful. Assuming everything is fine, head to the Maintenance tab, then the Scripts section.

From here, you can force the regular Mac maintenance script to run. After that, head to Rebuilding to force MacOS to rebuild a number of different caches — this can potentially solve slowdowns. The Cleaning section can also help, but largely overlaps with CCleaner as outlined above. As for the other configuration tools, feel free to explore, but for the most part, they aren’t meant to help with performance.
