MacworldIf your Mac is a few years old then you may well find that its not as quick on its feet as it used to be it may take a long time to start up properly, or to open and launch apps, or you may find that youre getting warnings about running out of disk space when you try to install new apps and software. Its relatively rare for your Macs physical hardware such as its internal hard-drive or solid-state drive to actually malfunction, but you may sometimes find that your drive is simply stuffed to the gills with old apps and files that are clogging up your system and slowing everything down.Storage SettingsApple does provide some help for these problems, and the macOS includes a number of built-in options that can help if you need to reclaim some of your Macs storage. In Ventura (13.0) and later versions of the macOS you can go to the Apple Menu to open the System Settings panel, select General and then select Storage. For older versions of the macOS you need to open the Apple Menu, select About This Mac, and then select Storage.The Storage settings panel gives you a break-down of how much storage your Macs drive has, how much has been used, and even the amount of space taken up by different types of files. You can see how much space is taken up by all your personal and work-related documents, your Photos and Music libraries, as well as Mail messages and other types of files. I was surprised to find that my MacBook had a whopping 30GB of files sitting in the Trash (Bin), so I could grab back 30GB of storage just by remembering to empty the Trash more often. Fortunately, the Storage Settings panel does include a number of options for managing your Macs storage including an option to empty the Trash automatically once a month. Theres also an Optimize Storage feature that deletes films and TV shows that youve already watched on Apple TV, and you can also save space by moving a lot of your files off your Mac up into iCloud Drive, although, of course, youll need to sign up for an iCloud+ subscription if you need more than the 5GB of online storage that Apple provides for free. (We have details of Apples iCloud storage plans here).PROMOTIONCleanMyMac X | Look inside your macOSFind hidden junk and free up the unseen System storage.

Its not difficult to delete old files and documents that you dont need anymore although sometimes the hard part is simply remembering where you left them all in the first place. Its also easy to delete old apps, simply by dragging them from the Applications folder into the Bin. However, most apps also leave bits of data and other files floating around on your Macs drive as well, and these can still take up a lot of space even after youve deleted the main app itself.Theres also one other set of files that take up a lot of space that Apple really doesnt want you to touch at all. That, of course, is the macOS the Mac operating system itself. The macOS mainly lives in the System folder on your Macs hard drive, but it can also create lots of data files during daily use that can be found in various other locations on your Mac. Looking at the Storage Settings panel on my MacBook tells me that the macOS itself only takes up about 10GB of storage but theres another 20GB of system data files also stored on my Mac as well. I could probably save several gigabytes of storage space by deleting some of these files. However, Apple doesnt encourage you to mess with these system files yourself as there is a real possibility that you could accidentally delete something important and possibly even stop your Mac from working properly at all.What does CleanMyMac X do?CleanMyMacRead our reviewPrice When Reviewed:39,99 Best Prices Today:39.99 at MacPawThis is where a tool such as CleanMy Mac can come in handy. CleanMyMac was developed by MacPaw specifically to clear out old System files, unused apps and documents that might be slowing your Mac down. It also includes additional tools to remove malware and fine-tune your Macs performance. Its worth mentioning that the current version 5.x is called CleanMyMac and runs on macOS 11 (Big Sur) or later, but the previous version 4.x was called CleanMyMac X, and can still be downloaded for use on older versions of the macOS.You can buy CleanMyMac directly from the MacPaw website, with several options available. You can either buy it for a one-time fee of $119.95/101.95 or pay an annual subscription of $39.95/30.95. There are also multi-user licenses available, as well as student discounts and volume licenses for business users. MacPaw states that CleanMyMac has been notarized and approved by Apple, so it should be safe to download from the web. Theres also a version available from the Mac App Store as well, but that version of the program lacks a few features that are available in the full version that you buy directly from MacPaw, as Apple prefers to avoid features that delve too deeply into the macOS itself.CleanMyMac X is one of our favorite Mac cleaner apps that were reviewed and compared in our roundup of the best Mac cleaner apps.How to use CleanMyMac1.Smart ScanFoundryCleanMyMac provides a wide range of different tools, but theyre organized into five main categories, which are listed in the sidebar on the left-hand side of the apps main window. These categories are Cleanup, Protection, Performance, Applications and My Clutter (the icons for each category arent labelled, but theres a tool tip that appears when you hover your mouse over each icon).Theres also one other option available when you first launch the app, called Smart Care. This allows the app to automatically scan your Mac and make suggestions for all the different types of files that you can delete to save space, as well as other options for boosting your Macs performance. When the app has finished scanning your Mac it displays the results as a set of five tiles, which reflect the five main categories of tools within the program, so lets take a closer look at those now.2.CleanupFoundryTop of the list in the sidebar is the Cleanup category. There are four tools in here, with each tool represented by a tile that shows a quick summary of its results and the files that it has found. One of the most important tools is System Junk, which deals with those mysterious system data files that can be found scattered around various locations on your Macs drive. Fortunately, CleanMyMac knows where to look for these files and, most importantly, it knows how to delete system junk without affecting important files that your Mac needs in order to run properly.Theres a Trash Bins tool that can empty your main Bin, but if you give it permission it can also quickly clear out the trash bins that are included within apps like Photos or Mail too. The app can also locate multiple versions of binaries (programs) and documents that may be taking up extra space.3.Review Your ResultsScreenshotFoundryEach tile within CleanMyMac shows you a quick summary of the files that it has found, and you can quickly delete those files simply by pressing the Clean button. However, theres also a Review button for each tile that lets you delve a little deeper and shows you more details about the individual files that it has found. Ive got quite a few cache files left over from various games, so I can just go ahead and hit the Clean button to get rid of those automatically.4.ProtectionFoundryThe second set of tools within CleanMyMac is designed to protect both your Mac and your privacy. Again, theres a set of tiles that summarise the results for different tools, which include malware protection, temporary files left by Safari and other browsers, and aliases linked to recently opened apps and documents. CleanMyMac can scan your Mac for malware, but its worth stressing that it doesnt provide the same protection as dedicated anti-virus apps such as BitDefender or Norton, so its worth considering alternatives if you really are worried about viruses on your Mac.5.PerformanceFoundryPerformance is the main reason most of us decide to clean up our Macs, so this is a key set of tools. The three tiles here recommend a number of maintenance tasks that can help to keep things running smoothly. They also check for Login items that launch whenever your turn on your Mac, and items that may run in the background without you realizing. As you probably know, there is a similar option for showing Login and Background items in your Macs System Settings, but pressing the Review button in CleanMyMac may provide a little extra detail that may not show up in System Settings such as the fact that I have about 14 different Adobe apps running in the background on my MacBook. Integos Mac Internet Security is our recommendation in our round-up of Mac antivirus apps.6.ApplicationsScreenshotFoundryYou dont need CleanMyMac to tell you when theres an update available for the macOS, of course, but it can provide additional information about various apps that have updates available, or apps that you may have tried to remove in the recent past. Theres a tile that lists App Leftovers, which are files left behind when you delete the main application file itself (with my games library being a big offender here once more). There are also files that are sometimes left behind during the installation of new apps. CleanMyMac can also provide reminders about old applications that havent been used for a while, which you might be able to delete in order to free up some space.7.My ClutterFoundryWe all have lots of old files that we no longer need stored on our Mac drives, but sometimes it can be hard to remember where they all are. CleanMyMac can scan individual folders that you specify in order to locate duplicate files, old downloads that you dont need anymore, or particularly large files that are taking up a lot of space. It can detect duplicate photos too although it will ask for permission to scan your Photos library before doing so. Again, the tiles in CleanMyMac give you a quick summary of the files that its found, and you can press Review to browse through the various files in more detail before deleting them.8.Memory hogs and moreScreenshotFoundryOne feature of CleanMyMac that is sometimes overlooked is the pulldown menu that appears in your Macs main menu bar. This is available even when CleanMyMac itself isnt running, so its a good way of quickly checking to see if there are any problems on your Mac. Again, theres a series of tiles that provide quick summaries for details such as your laptops battery health and running temperature. It can show you the amount of memory and processor power being used by various apps, and lets you quickly shut down any apps that are hogging too much memory. It can even check the speed of your wi-fi network and tell you how much data youve downloaded recently.
